RESUMEN
BACKGROUND: Preoperative dental screening before cardiac valve surgery is widely accepted but its required scope remains unclear. This study evaluates two preoperative dental screening (PDS) approaches, a focused approach (FocA) and a comprehensive approach (CompA), to compare postsurgical 90-day mortality. METHODS: Retrospective cohort analysis was performed on all patients who underwent valve surgery at Brigham and Women's Hospital with FocA and Massachusetts General Hospital with CompA of PDS approach from January 2009 to December 2016. Patients with intravenous drug abuse and systemic infections were excluded. Univariate, multivariable, and subgroup analysis was performed. RESULTS: A total of 1835 patients were included in the study. With FocA 96% of patients (1097/1143) received dental clearance in a single encounter with 3.3% receiving radiographs and undergoing dental extractions. With CompA 35.5% of patients (245/692) received dental clearance in a single encounter, 94.2% received radiographs, and 21.8% underwent dental extractions. There was no significant difference in 90-day mortality when comparing both PDS approach (10% vs 8.4%, P = .257). This remained unchanged in a multivariable model after adjusting for risk factors (odds ratio:1.32 [95%CI:0.91-1.93] [P = .14]). Reoperation due to infection was less in FocA (0.5%) vs CompA (2.6) (P < .001) and postoperative septicemia was increased in the FocA (1.7%) cohort when compared to the CompA (0.7%) (P < .001) patients. CONCLUSIONS: There was no difference in post valve surgery 90-day mortality between patients who underwent a FocA vs CompA of PDS.

BACKGROUND: Patients with underlying interstitial lung disease (ILD) who undergo cardiac surgery are at high risk of postoperative pulmonary complications. It remains unclear if transcatheter aortic valve replacement (TAVR) offers any benefit over surgical aortic valve replacement (SAVR) in ILD patients with severe aortic stenosis. METHODS: All adult patients with a diagnosis of ILD who underwent either a TAVR or isolated SAVR between January 2002 and December 2017 were retrospectively reviewed. Operative mortality, 30-day readmissions, and adjusted 1-year survival were compared between the two cohorts. RESULTS: The overall cohort included 52 TAVR and 74 SAVR patients. While TAVR patients were significantly older (77.2 vs 72.9 years) with higher Society of Thoracic Surgeons predicted risk of mortality (STS-PROM) scores compared with SAVR patients (6.29 vs 4.49; all P < .02), operative mortality was similar (5.8% vs 4.1%; P = .45). Rates of postoperative stroke, permanent pacemaker implantation, reintubation, and 30-day readmissions did not differ between the two groups (all P > .46). However, TAVR was associated with significantly shorter hospital and intensive care unit (ICU) length of stay, shorter ventilation times, and less requirement for ICU admission (all P < .05). Thirty-day readmissions and adjusted 1-year survival were also similar between the two groups (hazard ratio for TAVR vs SAVR = 1.34; 95% CI: 0.7-2.6). CONCLUSIONS: Among ILD patients with symptomatic aortic stenosis, TAVR was associated with comparable operative and risk-adjusted 1-year survival to SAVR. TAVR patients also had shorter ventilator times, ICU and hospital stay despite being at higher risk. Together, our findings suggest that TAVR may be a better option in this unique cohort.

BACKGROUND: Opioid dependence has become a major health care issue. Pain management of invasive surgical procedures with opioids may potentially contribute to this epidemic. We sought to determine the association of opioid-prescribing patterns with chronic opioid use. METHODS: We retrospectively reviewed all patients undergoing isolated coronary artery bypass graft (CABG) procedures during 2016 at a single institution. Prescribing patterns and medication usage were compared between opioid-naïve and opioid-exposed patients (patients with reported opioid use within 30 days prior to surgery). Chronic opioid dependence was defined as opioid usage beyond 90 days after discharge. RESULTS: We included 284 opioid-naïve and 46 opioid-exposed patients. Although overall prescribing patterns were similar between groups, a higher proportion of opioid-exposed patients were prescribed a total dose >150 mg of oxycodone per discharge prescription (15.2% vs 4.9%; P = 0.024), and had a higher proportion of refills within 30 days (28.3% vs 10.9%; relative risk [RR] 3.2 [95% confidence interval (CI): 1.5-6.8]; all P < 0.05). The incidence of chronic opioid dependence was higher among opioid-exposed patients compared to opioid-naïve patients (21.7% vs 3.2%; RR 8.5 [95%CI: 3.2-22.3]; P = 0.001). CONCLUSIONS: Ongoing opioid use 3 months after CABG is present in 21.7% of opioid-exposed patients and 3.2% of opioid-naïve patients. These preliminary findings highlight the burden of prescribing patterns on the overall opioid epidemic and the need to develop alternative pain management strategies.

BACKGROUND: A lower rate of permanent pacemaker (PPM) has been linked to a target aortic implantation height (AIH) >0.70, following transcatheter aortic valve replacement (TAVR) with the SAPIEN 3 valve. Based on clinical experience, it was hypothesized that a higher AIH (≥0.85) would lower the rate of PPM implantation. METHODS: A total of 127 patients (66 females, 61 males; mean age 82 ± 8 years) underwent TAVR with the SAPIEN 3 valve between May 2015 and July 2016. AIH was defined as the proportion of the valve frame above the aortic annulus in the post-deployment aortogram. A target AIH (≥0.70) was achieved in 113 patients (89%). Cases were stratified into a High Implantation (HI) group (AIH ≥0.85; 33 patients) or a Standard Implantation (SI) group (AIH <0.85; 94 patients). RESULTS: The mean Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) score of all patients was 6.4 ± 3.5%. Preoperative right bundle branch block (RBBB) was prevalent in 13% of SI patients, and in 18% of HI patients (p = 0.56). There were no significant differences in operative mortality (3.2% versus 0%), median length of stay (2 days versus 3 days) and incidence of moderate-to-severe paravalvular leak (3.2% versus 0%; all p >0.410) between SI and HI patients, respectively. Likewise, the incidence of new PPM did not differ between the two groups (12% in HI versus 13% in SI; p ≥0.99). The mean AIH was similar for patients with PPM implantation (0.80 ± 0.08) compared to those without (0.78 ± 0.06; p = 0.520). Preoperative RBBB was significantly associated with PPM implantation (odds ratio (OR) 10.1; p = 0.002), and patients who underwent PPM implantation had a higher operative mortality (12.5% versus 1%; p = 0.040). CONCLUSIONS: Among TAVR patients who received the SAPIEN 3 heart valve, a higher AIH (≥0.85) was not associated with a lower rate of PPM implantation or increased operative mortality. Prior RBBB was the only independent risk factor for new PPM implantation. Long-term follow up is crucial in determining the clinical significance of PPM implantation.

BACKGROUND: Coronary endarterectomy and patch angioplasty for the left anterior descending (LAD) artery have been shown to be effective adjunct techniques to surgical revascularization for severe coronary lesions. The objective of this study is to review the short- and long-term results of these two methods in our institution. METHODS: We retrospectively reviewed 166 consecutive patients who underwent internal thoracic artery grafting to the LAD, with either adjunct endarterectomy (95 patients) or patch angioplasty (71 patients) between 2002 and 2014. We compared the early and late outcomes between groups. RESULTS: The endarterectomy patients were older than the patch angioplasty patients (71 vs. 67 years, p = 0.007) and had lower rates of recent myocardial infarction (25% vs. 45%, respectively, p = 0.008). Median pulmonary bypass times and aortic cross clamp times were significantly longer in the endarterectomy group compared with the patch angioplasty group by 47 minutes (p < 0.001) and 42 minutes (p < 0.001), respectively. Median follow-up time was 6.9 years. No significant differences in operative mortality, perioperative myocardial infarction, and long-term survival were found. Freedom from percutaneous coronary intervention at 1 and 5 years was significantly higher in the endarterectomy group compared with the patch angioplasty group (p = 0.002). CONCLUSIONS: Endarterectomy and patch angioplasty are comparable methods to reach complete revascularization for highly selected patients with diffuse atherosclerotic disease in the LAD. Compared with patch angioplasty, complete extraction of the atherosclerotic plaque with an endarterectomy leads to similar short-term outcomes and long-term survival while significantly reducing the need for further interventions in the future.

BACKGROUND: Acute pulmonary embolism (PE) with preserved hemodynamics but right ventricular dysfunction, classified as submassive PE, carries a high risk of mortality. We report the results for patients who did not qualify for medical therapy and required treatment of submassive PE with surgical pulmonary embolectomy and catheter-directed thrombolysis (CDT). METHODS: Between October 1999 and May 2015, 133 submassive PE patients underwent treatment with pulmonary embolectomy (71) and CDT (62). A multidisciplinary PE response team helped to determine the most appropriate treatment strategy on a case-by-case basis. The EkoSonic ultrasound-facilitated thrombolysis system (EKOS) was used for CDT, which was introduced in 2010. RESULTS: The mean age of submassive PE patients was 57.3 years, which included 36.8% females. PE risk factors included previous deep venous thrombosis (46.6%), immobility (36.1%), recent surgery (30.8%), and cancer (22.6%), P < 0.05. The most common indication for advanced treatment was right ventricular strain (42.9%), P = 0.03. The frequency of surgical pulmonary embolectomy remained stable even after incorporating the EKOS procedure into our treatment algorithm, with statistically similar operative mortality. Bleeding was observed in six CDT patients and one pulmonary embolectomy patient (P < 0.05). Follow-up echocardiography was available for 61% of the overall cohort, of whom 76.5% had no residual moderate or severe right ventricular dysfunction. CONCLUSIONS: Pulmonary embolectomy and CDT are important contemporary advanced treatment options for selected high-risk patients with submassive PE, who do not qualify for medical therapy.

BACKGROUND AND AIM OF THE STUDY: The advantages of minimally invasive aortic valve replacement (AVR) are well documented, but whether the benefits extend to subsequent reoperative aortic valve surgery and beyond is unknown. The study aim was to compare in-hospital outcomes and long-term survival following reoperative AVR between patients who had previous undergone either minimally invasive AVR (mini-AVR) or full sternotomy AVR (sAVR). METHODS: All reoperative, isolated AVRs performed between July 1997 and September 2013 at the authors' institution, with or without non-complex aortic surgery, were identified. Patients were excluded if AVR was not isolated, had occurred prior to July 1997, or if the initial AVR was performed before the patient was aged 18 years. All reoperations were performed through a full sternotomy. The main outcomes of interest were operative results and long-term survival. RESULTS: A total of 101 patients was identified, of which 34 had undergone previous mini-AVR and 67 previous sAVR. The time from the previous AVR was similar in both groups (median 7.6 years overall). Of previous valve implants, 57 were bioprostheses and 44 mechanical; structural valve degeneration was the most common indication for surgery (43/101). Mini-AVR and sAVR patients did not differ significantly with regards to patient demographics and preoperative risk factors. A strong trend towards shorter skin-to-skin operative times was observed for mini-AVR (330 min versus 356 min; p = 0.053). Postoperatively, mini-AVR patients had a shorter ventilation time (5.7 h versus 8.4 h; p = 0.005), intensive care unit stay (37 h versus 63 h; p ≤ 0.001) and hospital length of stay (6.5 days versus 8.0 days; p = 0.038). There was one operative mortality in the sAVR, and none in the mini-AVR group. Mid-term survival at one and five years for mini-AVR was 100% (95% CI 100-100) and 100% (95% CI 100-100), and for sAVR was 93.9% (95% CI 88.2-99.7) and 85.0% (95% CI 75.1-94.9), respectively (p = 0.041). CONCLUSION: Mini-AVR confers benefits during subsequent reoperative AVR, with shorter hospital stays and improved long-term survival. These findings suggest that mini-AVR should be considered for patients at risk for aortic valve reoperation, and describes a previously unreported advantage of this well-established technique.

BACKGROUND: Del Nido cardioplegia, a crystalloid-based solution with lidocaine as a key element, is given as a single dose and has been used successfully in congenital cardiac surgery. HYPOTHESIS: We retrospectively compared a lidocaine containing "modified del Nido" solution with our standard whole blood cardioplegia to investigate its safety and efficacy in adult cardiac surgery. METHODS: From June 1, 2013 to December 30, 2013, we used a single dose of lidocaine containing cardioplegia (LC group) in 92 consecutive operations. Propensity matching analysis was undertaken to compare the outcomes of such patients with those who underwent their surgery by the same surgeon using standard whole blood cardioplegia (WB group), n = 396. Propensity score matching yielded 79 pairs of patients. RESULTS: After propensity matching, LC and WB groups were similar in baseline operative characteristics including cross-clamp time (LC: 65 minutes [range 54 to 89] vs. WB: 70 minutes [54 to 86], p = 0.993). Postoperative outcomes were similar including inotropic requirements (30.4% [24/72] vs. 25.3% [20/72], p < 0.60), median ventilation time (4.7 hours vs. 5.3, p < 0.74) and median length of stay was seven days for both groups (p < 0.82). Despite higher median postoperative, 24-hour CK-MB levels LC group (LC:22.3 ng/ml, range [15.6 to 40.3] vs. WB:18.4 ng/ml [13.9 to 28.2], p = 0.040), operative and one-year mortality were comparable among study groups (both p > 0.798). CONCLUSIONS: Lidocaine containing cardioplegia appears to be safe in adults undergoing cardiac procedure when administered for the first 60 minutes of aortic cross clamping. Higher CK-MB levels did not translate into adverse clinical outcomes.

BACKGROUND: Surgical treatment of asymptomatic severe aortic stenosis (AS) has been gaining attention ever since the results of the Early Surgery Versus Conventional Treatment in Very Severe Aortic Stenosis (RECOVERY) and Aortic Valve replacement versus conservative treatment in Asymptomatic seveRe aortic stenosis (AVATAR) trials showed survival benefits with early surgical aortic valve replacement (SAVR). This study analyzed the long-term clinical and echocardiographic outcomes of SAVR in asymptomatic severe AS. METHODS: Between 2002 and 2020, 272 patients with asymptomatic severe AS and a left ventricular ejection fraction ≥50% underwent SAVR with or without concomitant aortic surgery and met the study criteria. The median follow-up was 8.5 years (interquartile range, 6-12.8 years), for a total of 2584 patient-years. The time course of the left ventricular mass index (LVMI) and the average E/E' (ratio of the Doppler-derived E wave to the tissue Doppler-derived E' wave) were assessed using 594 postoperative echocardiograms. The association of preoperative LVMI and average E/E' with survival was assessed using Cox proportional hazards. RESULTS: There was no operative mortality. On longitudinal analyses, LVMI improved in patients who presented with moderate or severe preoperative left ventricular hypertrophy (LVH). However, after the early decline in average E/E', there was a late increase to greater than upper limit normal, particularly in patients with a preoperative average E/E'≥14. Postoperative survival was 100%, 94%, 84%, and 76% at 1, 5, 10, and 15 years, respectively, comparable to age- and sex-matched expected survival on the basis of the US general population. On adjusted Cox survival analysis, only moderate to severe LVH was associated with a survival penalty (hazard ratio], 2.32; 95% CI, 1.02-5.27; P = .045). CONCLUSIONS: In asymptomatic patients with AS, SAVR restores survival and improves LVH, but patients with diastolic dysfunction are left with persistent dysfunction. Presentation with moderate or severe LVH at the time of surgery translated to a survival penalty. This observational study supports early SAVR in this population before development of LVH, although further investigation is needed.

OBJECTIVES: As the application of transcatheter aortic valve replacement (TAVR) expands, the longitudinal implications of periprocedural complications are increasingly relevant. We examine the influence of TAVR complications on midterm survival. METHODS: Patients undergoing transfemoral TAVR at our institution between November 2011 and June 2018 were reviewed. Stroke severity was classified according to the National Institutes of Health stroke score. Kaplan-Meier analysis was used to assess survival, and a Cox proportional hazards model was created to examine independent associations with survival. The median follow-up time was 36 months for a total of 2789 patient-years. RESULTS: Overall, 866 patients were included. The mean age was 80 ± 9.5 years and mean Society of Thoracic Surgeons score was 4.8% ± 2.7%. The mortality rate at 30-days was 2.8% and 11.8% at 1 year. In-hospital left bundle branch block and 30-day permanent pacemaker insertion occurred in 14.8% and 7.9%, respectively. Postprocedural greater-than-mild paravalvular leak was present in 4.4% and stroke occurred in 3.8% at 30-days. Greater-than-mild paravalvular leak was associated with decreased survival at 2 years (P = .02), but not at 5 years. Severe stroke was independently associated with decreased survival at 5 years (hazard ratio, 5.73; 95% confidence interval, 2.29-14.36; P ≤ .001); however, the effect of nonsevere stroke did not reach significance (hazard ratio, 1.69; 95% confidence interval, 0.82-3.47; P = .152). CONCLUSIONS: Severe stroke was independently associated with decreased 5-year survival and initial risks associated with paravalvular leak may be attenuated over the midterm following transfemoral TAVR. Strategies to minimize the incidence of stroke and paravalvular leak must be prioritized to improve longitudinal outcomes after TAVR.

BACKGROUND: Volume-outcome relationships have been described for mitral valve repair at the institution and surgeon level. We aimed to assess whether this relationship is mitigated at high-volume (HV) mitral repair centers between HV and low-volume (LV) surgeons. METHODS: All mitral repair cases at an HV mitral center (mean, 192 annual repairs) from 1992 to 2018 were considered. Cases with concomitant procedures other than tricuspid and atrial fibrillation procedures were excluded. Surgeons who performed ≥25 repairs per year were considered HV. The primary outcome was operative mortality; secondary outcomes were operative complications, long-term mortality, and reoperation. RESULTS: In total, 2653 mitral repairs from 19 surgeons were included. The mean age of the patients in the HV and LV groups was 59.6 years and 61.8 years, respectively (P = .005), with no difference in other baseline characteristics. HV surgeons had significantly shorter median aortic cross-clamp times (80 vs 87 minutes; P < .001) compared with LV surgeons; however, there was no significant difference in operative mortality (0.9% vs 1.6%; P = .19), reoperation, perioperative complications, or length of stay. LV surgeons had higher repair conversion to replacement than HV surgeons did (9.0% vs 3.4%; P < .001). In the risk-adjusted analyses, surgeon volume group did not have an impact on longitudinal survival or reoperation. CONCLUSIONS: At an HV mitral repair institution, LV surgeons appear to have short- and long-term outcomes similar to those of HV surgeons despite increased conversion rates. These findings suggest that institutional volume may mitigate the surgeon volume outcome. However, complex repairs may benefit from referral to HV surgeons, given the lower conversion rate.

Objective: With expanding eligibility criteria, transcatheter aortic valve replacement is being performed on patients with longer life expectancy, and subsequent procedures after index transcatheter aortic valve replacement are inevitable. This study examines the incidence and outcomes of patients undergoing subsequent procedural readmissions after transcatheter aortic valve replacement. Methods: All patients who underwent index transcatheter aortic valve replacement and were discharged alive from January 2012 to December 2019 at a single institution were evaluated. Study end points were mortality and readmission for procedure with more than 1-day hospital stay. Effect on survival was evaluated by treating procedural readmission as a time-dependent variable by Cox proportional hazard model and competing risk analysis. Results: A total of 1092 patients met inclusion criteria with a median follow-up time of 34 months. A total of 218 patients (20.0%) had 244 subsequent procedural readmissions. During the 244 procedural readmissions, there were 260 procedures; 96 (36.9%) were cardiac (most commonly pacemaker implantation, percutaneous coronary interventions, and surgical aortic valve replacements), and 164 (63.1%) were noncardiac (most commonly orthopedic and gastrointestinal procedures). The overall procedural readmission rates were 32%, 39%, and 42%, and all-cause mortality was 27%, 44%, and 54% at 20, 40, and 60 months, respectively. Procedural readmissions were not associated with a survival penalty in any surgical risk group or on Cox regression (hazard ratio, 1.25; 0.91-1.64, P = .17). Conclusions: After transcatheter aortic valve replacement, procedural interventions are seen frequently, with most procedures occurring within the first year after transcatheter aortic valve replacement. However, subsequent procedural readmissions do not appear to have a survival penalty for patients after transcatheter aortic valve replacement. After transcatheter aortic valve replacement with resolution of aortic stenosis, subsequent procedures can and should be pursued if they are needed.
RESUMEN
OBJECTIVE: Transatrial transcatheter mitral valve replacement reduces complexity during mitral valve replacements involving high-risk patients with mitral annular calcification. This study examines trends in transatrial transcatheter mitral valve replacement use and outcomes. METHODS: Patients in the Society of Thoracic Surgeons database from 2014 to 2021 with mitral annular calcification undergoing transatrial transcatheter mitral valve replacement were included. Exclusion criteria were hypertrophic cardiomyopathy, congenital mitral valve disease, ventricular assist device placement, or prior mitral valve surgery. Primary outcomes were operative mortality and major adverse cardiac events compared between the Early (2014-2017, N = 71) and Recent (2018-2021, N = 151) eras. Parsimonious multivariable regression assessed select possible confounders for trends in major adverse cardiac events. RESULTS: Overall, 222 transatrial transcatheter mitral valve replacements at 104 hospitals were identified. Annual volume increased from 6 in 2014 to 43 in 2021. Median hospital volume was 1, maximum hospital volume was 17, and 10 or more replacements were performed at 4 hospitals. Mortality and major adverse cardiac events occurred in 10.4% and 22.5% of patients, respectively. Compared with the Early era patients, Recent era patients were more often elective (79.5% vs 64.8%) and were approached via sternotomy (90.1% vs 80.3%, all P < .05). Despite similar predicted risk of mortality (9.6% ± 11.1% vs 11.0% ± 6.0%; P = .61), Recent patients had reduced mortality (3.3% vs 25.4%, P < .001) and major adverse cardiac events (18.5% vs 31.0%; P = .057). On univariate and multivariable analyses, the Recent surgical era was significantly associated with lower mortality (0.10 [0.04-0.29]; P < .001) and lower major adverse cardiac events (0.48 [0.25-0.94]; P = .032), respectively. There were no preoperative characteristics that were significant confounders for the difference in major adverse cardiac events. CONCLUSIONS: Mortality and major adverse cardiac events after transatrial transcatheter mitral valve replacement have decreased significantly in the contemporary era independent of changes in major patient and operative characteristics. Transatrial transcatheter mitral valve replacement will have a future role in patients with mitral annular calcification.
RESUMEN
BACKGROUND: The rate of chronic opioid use after cardiac surgery is high compared with other surgical specialties; however evidence regarding optimal prescribing is limited. The purpose of this study was to evaluate patterns of opioid consumption after cardiac surgery to guide prescribing practices. METHODS: Consecutive patients undergoing sternotomy-based cardiac operations were considered for enrollment. Patients with opioid use within 3 months of surgery and those discharged to a nonhome facility were excluded. A patient diary and researcher-directed pill count was used to track pain and opioid use for 10 days after discharge. RESULTS: One hundred four patients were included in the final analysis. Of the 63 patients discharged with an opioid, 22 (34.9%) used none and 12 (19.0%) used fewer than half of the pills prescribed. Overall, pain and opioid consumption decreased significantly throughout the discharge period (P < .001). In those who used opioids after discharge, median total consumption was 64 morphine milligram equivalents (interquartile range, 38-128), or the equivalent of 9 oxycodone 5-mg tablets. Patients who used opioids were younger (60.9 vs 70.0, P < .001), but there were no differences based on sex, history of substance use, smoking, or procedure. After risk adjustment the mean pain score ≥ 3 on the day of discharge was predictive of opioid use (odds ratio, 2.9; 95% confidence interval, 1.8-4.8; P < .001). Most patients (88.5%) were satisfied or very satisfied with pain management. CONCLUSIONS: Fewer than half of all patients used opioids after discharge in this study. These data support the need for the development of prescription recommendations after cardiac surgery.

Objectives: The use of bioprosthetic aortic valve replacement (AVR) is inherently associated with a risk of structural valve degeneration (SVD) and the need for aortic valve (AV) reintervention. We sought to evaluate whether AV reintervention, in the form of repeat surgical AVR (SAVR) or valve-in-valve transcatheter aortic valve replacement (ViV-TAVR), negatively affects patients' subsequent long-term survival after index SAVR. Methods: We identified patients who had undergone bioprosthetic SAVR from 2002 to 2017 at our institution. Median longitudinal follow-up after index SAVR was 7.3 years (10.9 years for those with and 7.2 years for those without AV reintervention), and median follow-up after AV reintervention was 1.9 years. Cox regression analyses using AV reintervention (re-SAVR and ViV-TAVR) as a time-varying covariate were used to determine the impact of reintervention on subsequent survival. Results: Of 4167 patients who underwent index SAVR, 139 (3.3%) required AV reintervention for SVD, with re-SAVR being performed in 65 and ViV-TAVR in 74. Median age at the index SAVR was 73 years (interquartile range, 64-79 years), and 2541 (61%) were male. Overall, there were total of 1171 mortalities observed, of which 13 occurred after re-SAVR and 9 after ViV-TAVR. AV reintervention was associated with a greater risk of subsequent mortality compared with those patients who did not require AV reintervention (hazard ratio, 2.53; 95% confidence interval, 1.64-3.88, P < .001). This increased risk of subsequent mortality was more pronounced for those who received their index AVR when <65 years of age (hazard ratio, 5.60; 95% confidence interval, 2.57-12.22, P < .001) versus those ≥65 years (2.06, 1.21-3.52, P = .008). Direct comparison of survival between those who underwent re-SAVR versus ViV-TAVR showed 5-year survival to be comparable (re-SAVR: 74% vs ViV-TAVR: 80%, P = .67). Conclusions: Among patients receiving bioprosthetic AVR, an AV reintervention for SVD is associated with an increased risk of subsequent mortality, regardless of re-SAVR or ViV-TAVR, and this risk is greater among younger patients. These findings should be balanced with individual preferences at index AVR in the context of patients' lifetime management of aortic stenosis.
RESUMEN
OBJECTIVES: Mitral valve repair (MVP) is the gold standard treatment for degenerative mitral regurgitation. With the expansion of transcatheter technologies, this study compares the outcome of MVP in low-risk and non-low-risk patients to serve as a benchmark. METHODS: This retrospective, single-institution study examined all patients who underwent MVP for primary mitral regurgitation from 2005 to 2018. Patients were stratified into 2 risk categories: low-risk [Society of Thoracic Surgeons (STS) Predicted Risk of Mortality (STS-PROM) ≤2%] and non-low risk (STS-PROM > 2% or age > 75), with a subgroup of very low risk (STS-PROM ≤1%, age <75). RESULTS: A total of 1207 patients were included, and 1053 patients were classified as low risk and 154 as non-low risk. The non-low-risk group was significantly older, more likely to be female, and had a higher comorbidity burden than the low-risk group (all P < 0.01). For the low-risk group, the observed-to-expected (O:E) STS mortality ratio was 0.4 and the composite morbidity and mortality ratio was 0.6, whereas for the non-low risk, the O:E mortality was 1.5 and the composite morbidity and mortality was 0.9. When the subgroup of very low-risk group was assessed, the mortality O:E ratio was 0. CONCLUSIONS: The observed composite morbidity and mortality of patients undergoing MVP were persistently lower in low-risk patients, mainly driven by the very low-risk group. The excellent outcome of MVP in low-risk patients should be validated on a national level to determine how transcatheter technologies can be utilized in these patients.

BACKGROUND: Atrial functional mitral regurgitation (FMR) occurs because of left atrial dilatation or atrial fibrillation in heart failure with preserved left ventricular (LV) function, contrary to ventricular FMR, which occurs because of LV dysfunction. Despite pathophysiological differences, current guidelines do not discriminate between these 2 entities. METHODS: From January 2002 to March 2019, all adult patients with ≥3+ mitral regurgitation who underwent mitral valve repair or replacement were identified. Postoperative outcomes and midterm time-to-event rates (survival and reoperation) were compared. RESULTS: Overall, 94 atrial FMR (mean age, 67.6 years) and 84 ventricular FMR (mean age, 64 years) patients met inclusion criteria. Differences in baseline cardiac morphology and function of the atrial FMR and ventricular FMR patients were as follows: concomitant atrial fibrillation (37.2% vs 14.3%), heart failure (42.6% vs 63.1%), LV ejection fraction (60% vs 37%), at least moderate LV dilation (4.8% vs 40.6%), and moderate/severe right heart dysfunction (15.2% vs 5.1%), respectively. Operative mortality was 0% in the atrial FMR versus 1.2% in the ventricular FMR cohort. Actuarial estimates of survival and freedom from reoperation at 5 and 10 years was significantly higher in the atrial FMR cohort versus the ventricular FMR cohort. Ventricular FMR also remained a significant predictor of midterm mortality in our risk-adjusted analysis (adjusted hazard ratio for ventricular FMR, 1.8; 95% confidence interval, 1.001-3.26). CONCLUSIONS: There are important differences in baseline characteristics in terms of cardiac morphology and function among atrial FMR and ventricular FMR patients, which appear to affect in-hospital and midterm outcomes. Because of these discrepancies, early discrimination between these 2 etiologies of FMR might facilitate more tailored approaches to management.

Studies have shown improved outcomes among married patients who underwent cardiovascular surgery; however, this has not been well studied in transcatheter aortic valve implantation (TAVi). We examined the impact of marital status and patient sex on outcomes after TAVi. Patients who underwent TAVi from January 2015 to June 2018 were reviewed and stratified into 3 groups: single, married, and widowed. The impact of marital status and sex on 30-day outcomes was assessed using a stepwise logistic regression analysis. Cumulative survival was estimated using Kaplan-Meier analysis and adjusted survival with multivariable Cox proportional hazards modeling. A total of 785 patients were included: 149 single, 413 married, and 223 widowed. Widowed patients were older (84 vs 79 years) with higher Society of Thoracic Surgeons risk scores (6.79% vs 5.51%, both p ≤0.001) than married patients. Neither marital status nor sex was associated with 30-day mortality or home discharge. However, 1-year survival revealed a differential survival penalty, with married females (p = 0.041) having lower survival and married males (p = 0.007) having higher survival than their single counterparts. This survival penalty persisted in the adjusted analyses (married females hazard ratio [HR] 2.24, p = 0.009; widowed males HR 2.42, p = 0.057). For patients who were readmitted in the first year, adjusted analysis showed widowed status was associated with higher 30-day readmissions (HR 1.91, p = 0.012) in both sexes. In conclusion, these findings suggest that marital status does not impact both sexes equally after TAVi; identifying at-risk patients and targeted interventions, such as adjusting discharge planning to ensure adequate home social support, may help improve outcomes.

BACKGROUND: With wide expansion of transcatheter aortic valve replacement (TAVR) and dissemination of multidisciplinary-based approaches to care, societies are discussing the implementation of a tier system to valve centers. This study explores the impact of tier-based systems of care on surgical aortic valve replacement (SAVR) outcomes at institutions that perform SAVR only. METHODS: Medicare beneficiaries undergoing SAVR procedures from 2012 to 2015 were included. The SAVR hospitals were stratified into either tier A, valve centers with a TAVR program; or tier B, valve centers without a TAVR program. Adjusted survival, assessed by multivariable Cox regression, controlled for program type and patient risk profile. Time-dependent analysis accounted for hospitals that initiated a TAVR program during the study period. RESULTS: Overall, there were 562 tier A and 485 tier B SAVR hospitals. Tier A hospitals had significantly higher comorbidity burden compared with tier B hospitals (all P < .05) but had significantly lower rates of 30-day mortality (3.2% vs 4.1%) and 1-year mortality (8.1% vs 9.4%; both P < .05). After risk stratification, tier B hospitals had significantly worse 30-day mortality compared with tier A hospitals for all patient risk-profiles, except for the low-risk patients (P < .01). These findings persisted in the time-dependent analysis. Adjusted midterm survival was higher in tier A vs tier B hospitals. CONCLUSIONS: Low-risk patients can safely undergo SAVR in both tier level hospitals without compromising outcomes. Establishment of quality of care measures, especially in the SAVR-only hospitals, remains paramount and should be closely integrated when designing tier-based systems for aortic valve replacement care.

OBJECTIVE: To determine the impact of hospital size on national trend estimates of isolated open proximal aortic surgery for benchmarking hospital performance. METHODS: Patients age >18 years who underwent isolated open proximal aortic surgery for aneurysm and dissection from 2002 to 2014 were identified using the National Inpatient Sample. Concomitant valvular, vessel revascularization, re-do procedures, endovascular, and surgery for descending and thoracoabdominal aorta were excluded. Discharges were stratified by hospital size and analyzed using trend, multivariable regression, propensity-score matching analysis. RESULTS: Over a 13-year period, 53,657 isolated open proximal aortic operations were performed nationally. Although the total number of operations/year increased (â¼2.9%/year increase) and overall in-hospital mortality decreased (â¼4%/year; both P < .001 for trend), these did not differ by hospital size (P > .05). Large hospitals treated more sicker and older patients but had shorter length of stay and lower hospital costs (both P < .001). Even after propensity-score matching, large hospital continued to demonstrate superior in-hospital outcomes, although only statistically for major in-hospital cardiac complications compared with non-large hospitals. In our subgroup analysis of dissection versus non-dissection cohort, in-hospital mortality trends decreased only in the non-dissection cohort (P < .01) versus dissection cohort (P = .39), driven primarily by the impact of large hospitals (P < .01). CONCLUSIONS: This study demonstrates increasing volume and improving outcomes of isolated open proximal aortic surgeries nationally over the last decade regardless of hospital bed size. Moreover, the resource allocation of sicker patients to larger hospital resulted shorter length of stay and hospital costs, while maintaining similar operative mortality to small- and medium-sized hospitals.
