RESUMEN
Valve-in-Valve (ViV) Transcatheter aortic valve replacement (TAVR) has been associated with favorable outcomes in patients with degenerated stentless bioprosthesis. However, whether the outcomes after ViV TAVR for failed stentless bioprosthesis differ between balloon-expandable valves (BEV) and self-expanding valves (SEV) remains unknown. Therefore, we retrospectively analyzed 59 consecutive patients who underwent ViV TAVR for failed stentless bioprsothesis with BEV (N= 42) versus SEV (N= 17) in a single-healthcare system between 2013 and 2022. Overall, mean age was 70.8 years and 74.6% were males. Mean transcatheter valve size was 26.3 ±2.2 mm for BEV and 26.4 ±4 mm for SEV (p= 0.93). Mean STS score was 6.0 ±3.6 for BEV and 7.5 ±5.5 for SEV (p= 0.22). Compared with patients who received BEV, those who received SEV had higher rates of device malposition (2.4% vs. 23.5%; p< 0.01), post-deployment balloon dilation (11.9% vs. 35.5%; p= 0.04) and need for a second transcatheter device (2.4% vs. 35.5%; p< 0.01). However, both groups showed similar improvement in aortic valve function at 30-day and 1-year follow-up (incidence of 1-year severe patient-prosthesis mismatch in BEV: 17.6% vs. 14.3% in SEV; p= 0.78). One-year and 3-year mortality did not differ between BEV and SEV (11.9% vs. 11.8% and 25% vs. 30%; respectively; Log rank p= 0.9). In conclusion, performing ViV TAVR for failed stentless bioprsothesis is technically challenging, especially when using SEV, but satisfactory positioning is possible in most cases, with excellent hemodynamic and clinical outcomes with both BEV and SEV.
RESUMEN
BACKGROUND: Perioperative blood transfusion is associated with adverse outcomes and higher costs after coronary artery bypass graft (CABG) surgery. We developed risk assessments for patients' probability of perioperative transfusion and the expected transfusion volume to improve clinical management and resource use. METHODS: Among 1,266,545 consecutive (2008-2016) isolated CABG operations in The Society of Thoracic Surgeons Adult Cardiac Surgery Database, 657,821 (51.9%) received perioperative transfusions of red blood cells (RBC), fresh frozen plasma (FFP), cryoprecipitate, and/or platelets. We developed "full" models to predict perioperative transfusion of any blood product, and of RBC, FFP, or platelets. Using least absolute shrinkage and selection operator model selection, we built a rapid risk score based on 5 variables (age, body surface area, sex, preoperative hematocrit, and use of intra-aortic balloon pump). RESULTS: C statistics for the full model were 0.785, 0.815, 0.707, and 0.699 for any blood product, RBC, FFP, and platelets, respectively. C statistics for rapid risk assessments were 0.752, 0.785, 0.670, and 0.661 for any blood product, RBC, FFP, and platelets, respectively. The observed vs expected risk plots showed strong calibration for full models and risk assessment tools; absolute differences between observed and expected risks of transfusion were <10.8% in each percentile of expected risk. Risk assessment-predicted probabilities of transfusion were strongly and nonlinearly associated (P < .0001) with total units transfused. CONCLUSIONS: These robust and well-calibrated risk assessment tools for perioperative transfusion in CABG can inform surgeons regarding patients' risks and the number of RBC, FFP, and platelets units they can expect to need. This can aid in optimizing outcomes and increasing efficient use of blood products.
RESUMEN
Background: Among patients with bicuspid aortic valves (BAV) who are potential candidates for valve-sparing root replacement (VSRR), the long-term durability of this technique is not well understood. This study aimed to compare the clinical and echocardiographic outcomes of VSRR in those with BAV and tricuspid aortic valve (TAV) morphology. Methods: This was a retrospective analysis of patients who underwent VSRR between 2007 and 2021 at a single center. Kaplan-Meier and log-rank analysis were used to estimate and compare freedom from mortality, progression to >2+ aortic insufficiency (AI), and reoperation between groups (BAV vs TAV). Preoperative and postoperative echocardiographic data were collected and assessed for temporal changes in mixed-effect models. Results: A total ofâ¯185 patients (BAV, n = 52, 28.1%; TAV, n = 133, 71.9%) underwent VSRR. At baseline, BAV patients wereâ¯younger (42.4 ± 11.6 vs 52.3 ± 12.6 years; P < 0.01) and had more severe AI (47.9% vs 27.0%; P = 0.02). Average cardiopulmonary bypass and cross-clamp times were similar. There were no differences in rates of postoperative complications, intensive care unit or hospital days, or 30-day readmission. TAV patients' 1-, 5-, and 8-year survival rates were 99.2% [95% CI 97.8-100], 96.7% [93.5-99.9%], and 92.2% [85.6-99.3%], respectively. Overall, there were no differences between groups regarding freedom from mortality (P = 0.18), reoperation (P = 0.51), or recurrent >2+ AI (P = 0.97).â¯. Conclusions: VSRR can be safely performed on patients with BAV and TAV morphology, yielding similar midterm freedom from mortality, recurrent >2+ AI, and reoperation. This technique should be considered in carefully selected patients with aortic root pathology and BAV anatomy when performed at experienced centers.
RESUMEN
BACKGROUND: Diversity in the physician workforce improves patient care, physician well-being, and innovation. Workforce diversity is dependent on fair compensation that is unbiased by race or ethnicity. The purpose of this study was to determine whether a disparity of representation and salary on the basis of race or ethnicity exists in academic cardiothoracic surgery. METHODS: Study investigators performed a cross-sectional analysis of data collected by the Accreditation Council of Graduate Medical Education (ACGME) and the Association of American Medical Colleges (AAMC) faculty data for US medical school faculty 2021 and 2022. Salary data were not available if an academic rank and race or ethnicity had fewer than 6 cardiothoracic surgeons. Study investigators performed a descriptive analysis of the number of faculty and compared median and mean salaries according to academic rank using a paired t test. RESULTS: Of the 758 academic cardiothoracic surgeons, 64.9% were White, 25.2% were Asian, 3.3% were Black or African American, 4.9% were Hispanic or Latino, and 1.7% were of other race or ethnicity. Cardiothoracic surgeons at the academic rank of professor were 74.6% White, 17.7% Asian, 3.4% Black or African American, 3.9% Hispanic or Latino, and 0.4% other races. Asian faculty earned 89% to 171%, Black or African American faculty earned 59% to 94%, and Hispanic or Latino faculty earned 84% to 165% of the median salary earned by White faculty. Black or African American faculty consistently and significantly (P = .002) earned lower median salaries compared with White faculty at each academic rank measured. CONCLUSIONS: The academic cardiothoracic surgery workforce lacks diversity, especially at the highest academic ranks. Salary equity among races or ethnicities is complex, requiring additional study. However, Black or African American cardiothoracic surgeons experience low representation and salary disparity at every academic rank measured.
RESUMEN
Transcatheter tricuspid valve intervention (TTVI) has recently emerged as a promising alternative to surgery for tricuspid regurgitation (TR). However, a significant proportion of patients fail screening for TTVI, and little is known about their characteristics and natural history. This study sought to investigate causes of screen failure and outcomes of patients declined for TTVI. This was a retrospective single-center study of 32 patients who were ineligible for participation in transcatheter tricuspid valve replacement and tricuspid transcatheter edge-to-edge repair trials. Patients were classified into 2 groups according to the therapy they received: optimized medical therapy (OMT) group or intervention group. The mean age was 82 ± 7.8 years and 68.8% were women. The most common reasons for TTVI exclusion were anatomic/procedural impediment (53.1%), inclusion criteria not met (40.6%), and multivalvular disease (6.3%). Overall, 19 patients (59.4%) did not undergo subsequent tricuspid intervention. The clinical outcomes of these patients who received OMT alone were poor, with a 1-year composite of cardiac death or heart failure readmission of 47.4%. These rates were worse than in patients who subsequently underwent an intervention, albeit not statistically significant (OMT: 47.7% vs 23.1% interventions, p = 0.3), and were significantly more pronounced in the subgroup of patients who were excluded for anatomic/procedural limitations (OMT: 70% vs 14.3% interventions, p = 0.05). In conclusion, patients ineligible for TTVI, particularly, those with anatomic/procedural limitations, and treated medically have poor outcomes. These data underscore the importance of earlier referral and support the need for further transcatheter therapy iterations.

In acute coronary syndromes (ACS), revascularization is the standard of care. However, trials comparing contemporary coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are limited. Optimal revascularization in patients with multivessel coronary artery disease (MV-CAD) presenting with ACS is unclear. This is a multicentered, retrospective observational study from a large hospital system in the United States. We abstracted data in patients with MV-CAD and ACS from 2018 to 2022 who underwent revascularization with PCI, CABG, or medical management (MM). We evaluated multivariate statistics comparing categorical variables and outcomes, including all-cause mortality and myocardial infarction (MI) at 1 year. All logistic and Cox proportional-hazard models were balanced using inverse probability treatment weights accounting for age and gender. There were 295 patients with CABG (median age 66 years [interquartile range 59.7 to 73.1]; 73% male), 1,559 patients with PCI (median age 68.3 years [interquartile range 60 to 76.6]; 69.1% male], and 307 patients with MM (median age 70 years [60.9 to 77.1] 74% male]. Patients revascularized with PCI had greater all-cause mortality at 1 year (14.1% vs 5.1%; hazard ratio 2.4, confidence interval [1.5 to 3.8], p <0.001) and similar mortality to MM (13.4%). CABG also showed a reduced 1-year MI rate compared with PCI (1.7% vs 3.9%; hazard ratio 0.36, confidence interval 0.21 to 0.61, p ≤0.001), with a similar 1-year rate of MI to MM (3.9%). In conclusion, CABG is associated with lower mortality than are PCI and MM, and repeat ACS events at 1 year in patients with ACS and MV-CAD.

Proximal radial artery (PRA) access for cardiac catheterization is safe but can jeopardize subsequent use of the artery because of occlusion. Distal radial artery (DRA) access in the anatomical snuffbox preserves the RA but safety and potential detrimental effects on hand function are unknown. We aimed to assess hand function and complications after DRA and PRA. In this single-center trial, 300 patients were randomly allocated 1:1 to cardiac catheterization through DRA or PRA. The primary end point of change in hand function from baseline to 1 year was a composite of the Quick Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, hand grip test, and thumb-forefinger pinch test. The secondary end points included access feasibility and complications. Of 216 patients with 1-year completed follow-up, 112 were randomly allocated to DRA and 104 to PRA, with balanced demographics and procedural characteristics. Both groups had similar access site bleeding rates (DRA 0% vs PRA 1.4%, p = 0.25). Radial artery occlusion occurred in 1 PRA patient versus 2 in DRA. There was no significant difference in change of hand function, median (interquartile range) hand grip (DRA 0.7 [-3 to 4.5] vs PRA 1.3 [-2 to 4.3] kg, p = 0.57), pinch grip (DRA -0.1 [-1.1 to 1] vs PRA -0.3 [-1 to 0.7] kg, p = 0.66), and Quick DASH (DRA 0 [-6.6 to 2.3] vs PRA 0 [-4.6 to 2.9] points, p = 0.58). The composite of hand function was comparable between PRA and DRA. In conclusion, DRA is a safe strategy for cardiac catheterization, with a low complication rate. Compared with PRA, there is no increased risk of hand dysfunction or radial artery occlusion at 1 year.

Objective: Studies have shown that requiring tracheostomy following cardiac surgery has significant implications on outcomes. This study proposes a risk stratification model to predict the likelihood of requiring a tracheostomy after cardiac surgery. Methods: Patients who underwent cardiac surgery between January 2010 and December 2019 were analyzed. Kaplan-Meier analysis and log-rank test were used to estimate and compare survival between cohorts. A prediction model for the need for postoperative tracheostomy was developed with logistic regression combined with undersampling analysis. Results: A total of 9849 patients underwent cardiac surgery, and 176 (1.8%) required postoperative tracheostomy. Tracheostomy patients were older (mean age 68.4 ± 12.3 vs 65.9 ± 11.2 years; P < 0.01) and more likely female (43.8% vs 28.5%; P < 0.01). Predictors for requiring tracheostomy included hypertension (odds ratio [OR] 1.91; P = 0.05), New York Heart Association III/IV (OR 2.68; P < 0.001), chronic lung disease (OR 3.27; P < 0.001), and history of prior myocardial infarction (OR 3.32; P < 0.001). Three-year Kaplan-Meier survival was worse in patients who received tracheostomy (log-rank P < 0.001). Conclusions: A risk prediction model for requiring tracheostomy after cardiac surgery is proposed in this study. A history of New York Heart Association III/IV, chronic lung disease, and myocardial infarction as well as undergoing valve surgeries were associated with increased risk of requiring a tracheostomy.
RESUMEN
Background: In March 2022, a COVID-19 outbreak disrupted the global supply of iodine contrast media (ICM). Healthcare systems implemented contrast-saving strategies to maintain their remaining ICM supplies. This study sought to determine the impact of contrast shortage on the incidence of contrast-associated acute kidney injury (CA-AKI). Methods: This was a retrospective study of 265 patients undergoing 278 percutaneous coronary interventions (PCI) during 4-month periods prior to (9/1/2021 to 12/31/2021) and during (5/1/2022 to 8/31/2022) contrast shortage at a single center. The primary endpoint was the incidence of CA-AKI between study periods. Results: A total of 148 and 130 PCIs were performed before and during contrast shortage, respectively. The incidence of CA-AKI significantly decreased from 11.5% to 4.6% during contrast shortage (P = 0.04). During the shortage, average contrast volume per PCI was significantly lower (123 ± 62 mL vs 88 ± 46 mL, P < 0.001), while coronary imaging was significantly higher (34.3% vs 50%, P = 0.009) compared to preshortage. All-cause mortality at discharge was comparable between study periods (2.8% vs 3.3%, respectively; P = 0.90). Conclusion: The scarcity of ICM for PCI procedures in this single-center experience was associated with a significant increase in the utilization of intravascular imaging and a significant reduction in CA-AKI.
RESUMEN
Objectives: Deep venous thrombosis (DVT) is a known surgical complication that can lead to pulmonary embolism with subsequent morbidity and mortality. The incidence of DVT following coronary artery bypass grafting is unclear. Prophylaxis regimens vary and some guidelines advocate against use of routine chemoprophylaxis in patients at low-moderate risk for venous thromboembolism. We utilized postoperative lower extremity venous ultrasound to determine the incidence of DVT following coronary artery bypass grafting in patients with low- to moderate-risk of venous thromboembolism receiving aggressive postoperative DVT prophylaxis. Methods: This is a single-center, retrospective study of all patients who underwent coronary artery bypass grafting between April 2022 and January 2023. All patients who completed postoperative venous ultrasound of the bilateral lower extremities were initially included. Patients who underwent concurrent valve or aortic surgery, were at high risk of venous thromboembolism, or were receiving anticoagulation therapy for nonvenous thromboembolism indications were excluded. The primary outcome was in-hospital incidence of DVT. Secondary outcomes were rates of mortality, postoperative bleeding, and thromboembolic events from discharge to 30 days postoperatively and from 30 days to 3 months postoperatively. Results: No DVTs were observed in 211 included patients. In hospital, there were 3 significant bleeding events and 1 stroke. Following discharge there were 3 additional bleeding events, 1 death, 1 transient ischemic attack, and 1 pulmonary embolism. Conclusions: We observed a 0% rate of DVT in low- to moderate-risk patients undergoing isolated coronary artery bypass grafting and receiving a comprehensive DVT prophylaxis regimen. In hospital bleeding and other thromboembolic event rates were 2.84% and 0.47% respectively.
RESUMEN
BACKGROUND: Deep hypothermia has been the standard for hypothermic circulatory arrest (HCA) during aortic arch surgery. However, centers worldwide have shifted toward lesser hypothermia with antegrade cerebral perfusion. This has been supported by retrospective data, but there has yet to be a multicenter, prospective randomized study comparing deep versus moderate hypothermia during HCA. METHODS: This was a randomized single-blind trial (GOT ICE [Cognitive Effects of Body Temperature During Hypothermic Circulatory Arrest]) of patients undergoing arch surgery with HCA plus antegrade cerebral perfusion at 4 US referral aortic centers (August 2016-December 2021). Patients were randomized to 1 of 3 hypothermia groups: DP, deep (≤20.0 °C); LM, low-moderate (20.1-24.0 °C); and HM, high-moderate (24.1-28.0 °C). The primary outcome was composite global cognitive change score between baseline and 4 weeks postoperatively. Analysis followed the intention-to-treat principle to evaluate if: (1) LM noninferior to DP on global cognitive change score; (2) DP superior to HM. The secondary outcomes were domain-specific cognitive change scores, neuroimaging findings, quality of life, and adverse events. RESULTS: A total of 308 patients consented; 282 met inclusion and were randomized. A total of 273 completed surgery, and 251 completed the 4-week follow-up (DP, 85 [34%]; LM, 80 [34%]; HM, 86 [34%]). Mean global cognitive change score from baseline to 4 weeks in the LM group was noninferior to the DP group; likewise, no significant difference was observed between DP and HM. Noninferiority of LM versus DP, and lack of difference between DP and HM, remained for domain-specific cognitive change scores, except structured verbal memory, with noninferiority of LM versus DP not established and structured verbal memory better preserved in DP versus HM (P = 0.036). There were no significant differences in structural or functional magnetic resonance imaging brain imaging between groups postoperatively. Regardless of temperature, patients who underwent HCA demonstrated significant reductions in cerebral gray matter volume, cortical thickness, and regional brain functional connectivity. Thirty-day in-hospital mortality, major morbidity, and quality of life were not different between groups. CONCLUSIONS: This randomized multicenter study evaluating arch surgery HCA temperature strategies found low-moderate hypothermia noninferior to traditional deep hypothermia on global cognitive change 4 weeks after surgery, although in secondary analysis, structured verbal memory was better preserved in the deep group. The verbal memory differences in the low- and high-moderate groups and structural and functional connectivity reductions from baseline merit further investigation and suggest opportunities to further optimize brain perfusion during HCA.

Background Proximal radial artery (pRA) access for cardiac catheterization is safe but can jeopardize subsequent use of the artery because of occlusion. Distal radial artery (dRA) access in the anatomical snuffbox preserves the radial artery, but safety and potential detrimental effects on hand function are unknown. Methods and Results In the DIPRA (Distal Versus Proximal Radial Artery Access for Cardiac Catheterization and Intervention) study, a single-center trial, 300 patients were randomized 1:1 to cardiac catheterization through dRA or pRA. The primary end point of change in hand function from baseline to 30 days was a composite of the QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) questionnaire, hand-grip test, and thumb forefinger pinch test. Secondary end points included access feasibility and complications; 254 of 300 patients completed follow-up at 30 days; of these, 128 were randomized to dRA and 126 to pRA with balanced demographic and procedural characteristics. Both groups had similar rates of access site bleeding (dRA 0% versus pRA 1.4%; P=0.25). Six patients with dRA failed access compared with 2 patients with pRA. Radial artery occlusion occurred in 2 pRA versus none in dRA. There were no significant differences in change in hand function, median hand-grip (dRA 0 [-3.2, 3.3] versus pRA 0.7 [-2.3, 3.3] kg; P=0.21), pinch-grip (dRA -0.3 [-1.2, 0.5] versus pRA 0 [-0.9, 0.9] kg; P=0.09), and QuickDASH (dRA 0 [-4.6, 2.3] versus pRA 0 [-4.6, 2.3] points, P=0.96). There was no significant difference in the composite of hand function between pRA and dRA. Conclusions dRA is a safe strategy for cardiac catheterization with a low complication rate. Compared with pRA, there is no increased risk of hand dysfunction at 30 days. Registration URL: https://www.ClinicalTrials.gov. Unique identifier: NCT04318990.

OBJECTIVES: The Ross procedure is traditionally considered for young adult patients with aortic valve disease. This study compares long-term outcomes of patients undergoing the Ross procedure who are ≥50 and <50-years old. METHODS: Data were collected from 225 patients undergoing Ross procedure at a single centre from 1994 to 2019. Patients were categorized into younger (<50-years old; n = 156) and older (≥50-years old; n = 69) cohorts. Baseline demographics clinical outcomes were compared. RESULTS: The mean age was 36 ± 8.1 and 55 ± 4.2 years in the younger and older cohort, respectively. Both groups were predominantly male (58.5% vs 69.6%; P = 0.59). The younger group had a higher rate of aortic insufficiency (51% vs 26.1%; P < 0.01), and bicuspid aortic valve (81.4% vs 58.0%; P < 0.01). Aortic stenosis was more prevalent in the older cohort (25.6% vs 58.0%; P < 0.01). Operative mortality was acceptable in both groups (1.3% vs 4.3%; P = 0.15). Survival up to 10 years was not statistically different between 2 groups (96.2% vs 91.3% P = 0.16), whereas survival up to 15 years for younger patients was significantly higher (94.9% vs 85.5%; P = 0.03). After non-cardiac related deaths were excluded, survival up to 15 years (98.7% vs 91.3%; P = 0.02) was significantly lower than younger patients. In both groups, survival after the Ross procedure was similar to the age- and sex-matched US population. CONCLUSIONS: Survival up to 10 years after Ross procedure were similar, but up to 15 years was significantly higher in younger patients. The Ross procedure restored patients from both groups to expected survival. Our results suggest that at experienced centres, the Ross procedure is a safe and reasonable option for patients who are 50 years and older.

Introduction: Although a role for percutaneous Impella devices has been established, there is a paucity of data regarding the utility and outcomes of larger surgically implanted Impella devices. Methods: We conducted a retrospective review of all surgical Impella implants at our institution. All Impella 5.0 and Impella 5.5 devices were included. The primary outcome was survival. Secondary outcomes included hemodynamic and end-organ perfusion as well as commonly encountered surgical complications. Results: From 2012 to 2022, 90 surgical Impella devices were implanted. The median age was 63 [53-70] years, the mean creatinine was 2.07 ± 1.22 mg/dL, and the average lactate level was 3.32 ± 2.90 mmol/L. Prior to implantation, 47 patients (52%) were supported with vasoactive agents, while 43 (48%) were also supported with another device. The most common etiology of shock was acute on chronic heart failure (50, 56%), followed by acute myocardial infarction (22, 24%), and postcardiotomy (17, 19%). Overall, 69 patients (77%) survived to device removal, and 57 (65%) survived to hospital discharge. One-year survival was 54%. Neither etiology of heart failure nor device strategy was associated with 30-day or 1-year survival. On multivariable modeling, the number of vasoactive medications prior to device implantation was strongly associated with 30-day mortality (hazard ratio 1.94 [1.27-2.96], P < 0.01). Surgical Impella placement was associated with a significant decreased need for vasoactive infusions (P < 0.01) and decreased acidosis (P = 0.01). Conclusions: Surgical Impella support for patients in acute cardiogenic shock is associated with lower vasoactive medication use, improved hemodynamics, increased end-organ perfusion, and acceptable morbidity and mortality.
RESUMEN
Although left ventricular assist device (LVAD) implant is associated with an increased survival in patients with end-stage heart failure, severe right ventricular failure requiring a right ventricular assist device (RVAD) placement is associated with increased short-term morbidity and mortality. Patients not eligible for transplant have limited options, which may impact decision-making and outcomes at nontransplant centers. We conducted a retrospective review of all LVAD implants at our nontransplant center. Primary stratification was by the need for a postoperative RVAD implant. The primary outcome was survival. The Cox proportional hazards regression modeling was used to further evaluate mortality. From 2017 to 2022, 128 patients underwent a primary LVAD implant and 24 (18.75%) required a perioperative RVAD placement. RVAD implant was associated with increased operative mortality (1.92% vs 33.33%, p <0.01) and decreased 1-year (91.29% vs 60.60%, p <0.01) and 2-year survival (84.05% vs 36.36%, p <0.01). However, in patients who survived their index hospitalization, 1-year (93.00% vs 91.67%, p = 0.78) and 2-year (86.16% vs 55.00%, p = 0.10) mortality were similar. On multivariable analysis, the need for a RVAD was associated with an increased hazard of 1-year (5.60 [1.96 to 16.01], p <0.01) and 2-year (5.17 [2.01 to 13.28], p <0.01) mortality. In conclusion, our series from a nontransplant center suggests that patients who survive the implant have acceptable short-term survival, even if they do not have a transplant option; thus, carefully selected patients with biventricular failure may benefit from an LVAD implant, even if an RVAD is needed.
