RESUMEN
BACKGROUND: In patients with severe aortic stenosis (AS) and concomitant severe coronary artery disease (CAD), the relative merits of a combined percutaneous (transcatheter aortic valve implantation [TAVI] and percutaneous coronary intervention [PCI]] versus surgical approach (surgical aortic valve replacement [SAVR] and coronary artery bypass graft [CABG]) remain unknown. AIMS: To determine the utility of combined percutaneous versus surgical approaches in patients with severe AS and CAD. METHODS: The National Readmission Database (NRD) (2015-2019) was queried to identify all cases of TAVI+PCI and SAVR+CABG. The adjusted odds ratios (aOR) of mortality, stroke, and its composite (major adverse cardiovascular events [MACE]) were calculated using a propensity-score matched (PSM) analysis. RESULTS: A total of 89,314 (5358 TAVI+PCI, 83,956 SAVR+CABG) patients were included in the crude analysis. There was a gradual increase in the utilization of TAVI+PCI from 2016 to 2019 by 2%-4% per year. Using PSM, a subset of 11,361 (5358 TAVI+PCI, 6003 SAVR+CABG) patients with a balanced set of demographics and baseline comorbidities was selected. During index hospitalization, the adjusted odds of MACE (aOR 0.72, 95% confidence interval [CI] 0.62-0.83), and all-cause mortality (aOR 0.68, 95% CI 0.57-0.81) were significantly lower in patients undergoing TAVI+PCI compared with SAVR+CABG. However, patients undergoing TAVI+PCI had a higher incidence of MACE (aOR 1.40, 95% CI 1.05-1.87), and mortality (aOR 1.75, 95% CI 1.22-2.50) at 30-days. The risk of index-admission (aOR 0.82, 95% CI 0.62-1.09) and 30-day (aOR 0.88, 95% CI 0.51-1.51) stroke was similar between the two groups. CONCLUSION: In selected patients with severe AS and concomitant CAD, a combined percutaneous approach (TAVR+PCI) compared with SAVR+CABG may confer a lower risk of MACE and mortality during index admission but a higher incidence of 30-day complications.

BACKGROUND: As cardiovascular computed tomography (CCT) practice evolves, the demand for specialists continues to increase. However, CCT training remains variable globally with limited contemporaneous data to understand this heterogeneity. We sought to understand the role of CCT globally and the training available to underpin its use. METHODS: We performed two consecutive surveys of cardiology and radiology physicians, two years apart, utilizing the Society of Cardiovascular Computed Tomography (SCCT) website, weblinks, social media platforms, and meeting handouts to maximize our response rate. We compared United States (US)-based vs. international responses to understand global similarities and differences in practice and training in the surveys. RESULTS: 235 respondents (37% trainees and 63% educators/non-trainees) initiated the first survey with 174 (74%) completing the core survey, with 205 providing their work location (114 US and 91 international). Eighty-four percent (92/110) of educator respondents stated a need for increased training opportunities to meet growing demand. Dedicated training fellowships are heterogenous, with limited access to structural heart imaging training, despite structural scanning being performed within institutions. The lack of a standardized curriculum was identified as the main obstacle to effective CCT learning, particularly in the US, with web-based learning platforms being the most popular option for improving access to CCT training. 148 trainees initiated the second survey with 107 (72%) completing the core components (51% North America, 49% international). Only 68% said they would be able to meet their required CCT education needs via their training program. Obstacles in obtaining CCT training again included a lack of a developed curriculum (51%), a lack of dedicated training time (35%), and a lack of local faculty expertise (31%). There was regional variability in access to CCT training, and, in contrast to the first survey, most (89%) felt 1:1 live review of cases with trained/expert reader was most useful for improving CCT training alongside formal curriculum/live lectures (72%). CONCLUSIONS: There is a need to expand dedicated CCT training globally to meet the demand for complex CCT practice. Access to CCT education (didactic and 1:1 case-based teaching from expert faculty), implementation of recently published global training curricula, and increased teaching resources (web-based) as an adjunct to existing experiential learning opportunities, are all deemed necessary to address current educational shortfalls.

Coronary stent underexpansion is associated with restenosis and stent thrombosis. In clinical studies of atherosclerosis, high wall shear stress (WSS) has been associated with activation of prothrombotic pathways, upregulation of matrix metalloproteinases, and future myocardial infarction. We hypothesized that stent underexpansion is predictive of high WSS. WSS distribution was investigated in patients enrolled in the prospective randomized controlled study of angulated coronary arteries randomized to undergo percutaneous coronary intervention with R-ZES or X-EES. WSS was calculated from 3D reconstructions of arteries from intravascular ultrasound (IVUS) and angiography using computational fluid dynamics. A logistic regression model investigated the relationship between WSS and underexpansion and the relationship between underexpansion and stent platform. Mean age was 63±11, 78% were male, 35% had diabetes, mean pre-stent angulation was 36.7°±14.7°. Underexpansion was assessed in 83 patients (6,181 IVUS frames). Frames with stent underexpansion were significantly more likely to exhibit high WSS (> 2.5 Pa) compared to those without underexpansion with an OR of 2.197 (95% CI = [1.233-3.913], p = 0.008). There was no significant association between underexpansion and low WSS (< 1.0 Pa) and no significant differences in underexpansion between R-ZES and X-EES. In the Shear Stent randomized controlled study, underexpanded IVUS frames were more than twice as likely to be associated with high WSS than frames without underexpansion.

Background: The use of transcatheter aortic valve implantation (TAVI) in patients with aortic valve disease excluded from clinical trials has increased with no large-scale data on its safety. Objectives: The purpose of this study was to assess the trend of utilization and adjusted outcomes of TAVI in clinical trials excluded (CTE) vs clinical trials included TAVI (CTI-TAVI) patients. Methods: We used the National Readmission Database (2015-2019) to identify 15 CTE-TAVI conditions. A propensity score-matched analysis was used to calculate the adjusted odds ratio (aOR) of net adverse clinical events (composite of mortality, stroke, and major bleeding) in patients undergoing CTE-TAVI vs CTI-TAVI. Results: Among the 223,238 patients undergoing TAVI, CTE-TAVI was used in 41,408 patients (18.5%). The yearly trend showed a steep increase in CTE-TAVI utilization (P = 0.026). At index admission, the adjusted odds of net adverse clinical events (aOR: 1.83, 95% CI: 1.73-1.95) and its components, including mortality (aOR: 2.94, 95% CI: 2.66-3.24), stroke (aOR: 1.20, 95% CI: 1.07-1.34), and major bleeding (aOR: 1.49, 95% CI: 1.36-1.63) were significantly higher in CTE-TAVI compared with CTI-TAVI. Among the individual contraindications to clinical trial enrollment in the CTE-TAVI, patients with bicuspid aortic valve, leukopenia, and peptic ulcer disease appeared to have similar outcomes compared with CTI-TAVI, while patients with end-stage renal disease, bioprosthetic aortic valves, and coagulopathy had a higher readmission rate at 30 and 180 days. Conclusions: CTE-TAVI utilization has increased significantly over the 4-year study period. Patients undergoing CTE-TAVI have a higher likelihood of mortality, stroke, and bleeding than those undergoing CTI-TAVI.
RESUMEN
Background: Patients with severe aortic stenosis and cancer are often denied surgical aortic valve replacement (SAVR) due to a prohibitive risk of perioperative mortality. Objectives: The purpose of this study was to determine the safety of transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis and cancer. Methods: The Nationwide Inpatient Sample database (2002-2018) was used to study the outcomes of TAVI vs SAVR in patients with active or prior history of prostate, lung, colorectal, breast, and renal cancer. A propensity score-matched analysis to calculate adjusted odds ratios (aORs) for major adverse cardiovascular events (MACEs) and its components. Results: A total of 1,505,995 crude population and a subset of 345,413 noncancer and 33,565 cancer patients were selected on propensity score-matched analysis. The yearly trend showed a steep increase in the utilization of TAVI. Compared with SAVR, TAVI had a lower risk of in-hospital mortality in prostate cancer, while there was no difference among other cancer types. Patients with lung (aOR: 0.65; 95% CI: 0.43-0.97) and prostate cancer (aOR: 0.79; 95% CI: 0.66-0.96) had lower, while colorectal cancer (aOR: 1.43; 95% CI: 1.08-1.90) had higher odds of MACE with TAVI. The incidence of major bleeding was lower with TAVI (except for lung cancer), while the risk of stroke was similar (except for colorectal cancer) between TAVI and SAVR. Conclusions: TAVI in patients with prostate, breast, lung, and renal cancer appears to be a reasonable alternative to SAVR with lower or similar risks of mortality and MACE.
RESUMEN
Objective: To evaluate the prevalence, management and outcomes of concomitant aortic stenosis (AS) in admissions with acute myocardial infarction (AMI). Methods: We used the HCUP-NIS database (2000-2017) to identify adult AMI admissions with concomitant AS. Outcomes of interest included prevalence of AS, in-hospital mortality, use of cardiac procedures, hospitalization costs, length of stay, and discharge disposition. Results: Among a total of 11,622,528 AMI admissions, 513,688 (4.4 %) were identified with concomitant AS. Adjusted temporal trends revealed an increase in STEMI and NSTEMI hospitalizations with concomitant AS. Compared to admissions without AS, those with AS were on average older, of female sex, had higher comorbidity, higher rates of NSTEMI (78.9 % vs 62.1 %), acute non-cardiac organ failure, and cardiogenic shock. Concomitant AS was associated with significantly lower use of coronary angiography (45.5 % vs 64.4 %), percutaneous coronary intervention (20.1 % vs 42.5 %), coronary atherectomy (1.7 % vs. 2.8 %) and mechanical circulatory support (3.5 % vs 4.8 %) (all p < 0.001). Admissions with AS had higher rates of coronary artery bypass surgery and surgical aortic valve replacement (5.9 % vs 0.1 %) compared to those without AS. Admissions with AMI and AS had higher in-hospital mortality (9.2 % vs. 6.0 %; adjusted OR 1.12 [95 % CI 1.10-1.13]; p <0.001). Concomitant AS was associated with longer hospital stay, more frequent palliative care consultations and less frequent discharges to home. Conclusions: In this 18-year study, an increase in prevalence of AS in AMI hospitalization was noted. Concomitant AS was associated with lower use of guideline-directed therapies and worse clinical outcomes among AMI admissions.
RESUMEN
BACKGROUND: Transcatheter aortic valve implantation (TAVI) has increasingly been utilized in patients with bicuspid aortic valve (BAV) related aortic stenosis (AS) with insufficient large-scale data on its safety. METHODS: The Nationwide Inpatient Sample and Nationwide Readmission Database (2011-2018) were queried to identify patients undergoing TAVI for BAV versus trileaflet aortic valve (TAV) associated AS. The in-hospital, 30- and 180-day odds of outcomes were assessed using a propensity-matched analysis (PSM) to calculate adjusted odds ratios (aOR) with its 95% confidence interval (CI). RESULTS: A total of 216,723 TAVI (TAV: 214,050 and BAV: 2,673) crude and 5,347 matched population (TAV: 2,674 and BAV: 2,673) was included in the final analysis. At index admission, the adjusted odds of in-hospital mortality (aOR: 1.57, 95% CI: 0.67-3.66), stroke (aOR: 0.77, 95% CI: 0.38-1.57), cardiac tamponade (aOR: 0.75, 95% CI: 0.17-3.36), vascular complications (aOR: 0.33, 95% CI: 0.09-1.22), cardiogenic shock (aOR: 1.77, 95% CI: 0.93-3.38), paravalvular leak (aOR: 0.55, 95% CI: 0.26-1.14), need for mechanical circulatory support device, and permanent pacemaker implantation (PPM) (aOR: 1.02, 95% CI: 0.69-1.52) were not significantly different between TAVI for BAV versus TAV. At 30- and 180-day follow-up duration, the risk of stroke and major postprocedural complications remained similar, except that TAVI in BAV had a higher incidence of PPM implantation compared with TAV. The yearly trend showed an increase in the utilization of TAVI for both TAV and BAV and a steady decline in the overall annual rate of in-hospital complications. CONCLUSION: TAVI utilization in patients with BAV has increased over the recent years. The relative odds of in-hospital mortality, and all other major complications, were similar between patients undergoing TAVI for BAV- and TAV-related AS.

Contrast pulmonary angiography by hand injection or power injection is widely used during catheter-based therapies for acute submassive and massive pulmonary embolism (PE). Particularly, in patients with pre-existing chronic kidney disease, this approach may present a prognostic challenge owing to a double-contrast load, initially during computed tomographic pulmonary angiography (CTPA), and during percutaneous treatment. Intravascular ultrasound (IVUS) has been used as an adjunctive imaging modality in the percutaneous treatment of chronic thromboembolic pulmonary hypertension, and in coronary and peripheral vascular interventions. We report a series of cases illustrating the use of IVUS in the management of acute PE. All five patients presented with an acute submassive PE with evidence of right ventricular (RV) strain (RV/LV ratio ≥ 0.90). Body mass index and B-type natriuretic peptide ranged from 18 to 47 kgm/m2 and 56-932 pg/mL (ref. ≤ 78), respectively. Three of the five patients had renal impairment prior to the procedure (acute kidney injury, AKI, and chronic kidney injury, CKD). Post-catheter-directed pulmonary embolectomy there was a modest reduction in mean pulmonary artery pressure in all five patients (range: -4 mmHg to -9 mmHg). The first case serves as a proof of concept of IVUS use in acute PE. This case series demonstrates that an IVUS-only approach in the catheter-directed management of acute submassive PE is feasible and may be of particular importance in patients with pre-existing renal dysfunction.

OBJECTIVES: To investigate the long-term vasomotor response and inflammatory changes in Absorb bioresorbable vascular scaffold (BVS) and metallic drug-eluting stent (DES) implanted artery. BACKGROUND: Clinical evidence has demonstrated that compared to DES, BVS is associated with higher rates of target lesion failure. However, it is not known whether the higher event rates observed with BVS are related to endothelial dysfunction or inflammation associated with polymer degradation. METHODS: Ten Absorb BVS and six Xience V DES were randomly implanted in the main coronaries of six nonatherosclerotic swine. At 4-years, vasomotor response was evaluated in vivo by quantitative coronary angiography response to intracoronary infusion of Ach and ex vivo by the biomechanical response to prostaglandin F2-α (PGF2-α), substance P and bradykinin and gene expression analysis. RESULTS: Absorb BVS implanted arteries showed significantly restored vasoconstrictive responses after Ach compared to in-stent Xience V. The contractility of Absorb BVS treated segments induced by PGF2-α was significantly greater compared to Xience V treated segments and endothelial-dependent vasorelaxation was greater with Absorb BVS compared to Xience V. Gene expression analyses indicated the pro-inflammatory lymphotoxin-beta receptor (LTßR) signaling pathway was significantly upregulated in arteries treated with a metallic stent compared to Absorb BVS treated arterial segments. CONCLUSIONS: At 4 years, arteries treated with Absorb BVS compared with Xience V, demonstrate significantly greater restoration of vasomotor responses. Genetic analysis suggests mechanobiologic reparation of Absorb BVS treated arteries at 4 years as opposed to Xience V treated vessels.

AIMS: Heart failure in constrictive pericarditis (CP) is attributed to impaired biventricular diastolic filling. However, diseases that cause CP due to myocardial infiltration and fibrosis can also impair biventricular systolic function (sf) and contribute to heart failure. This study of patients with CP examined biventricular sf and the effect of myocardial infiltration by pericardial diseases and the resulting fibrosis on ventricular sf. METHODS AND RESULTS: Histopathologic examinations of right ventricular (RV) and left ventricular (LV) myocardia and pericardia were performed on three autopsied hearts of patients with pericardial diseases. Additionally, in 40 adults with clinical heart failure and 40 healthy adults (controls), sf of both ventricles was examined by echocardiography, including strain measurements, and biventricular diastolic filling and pulmonary artery pressures were assessed by cardiac catheterization. Cardiac histopathology indicated thickening of the pericardium with fibrosis, disease infiltrating the myocardium, greater infiltration of the RV than the LV, and an association of pericardial thickness with myocardial infiltrations. Functional analysis indicated that RVsf was impaired on all echo indices, including strain measurement, but LVsf was preserved. CONCLUSIONS: Diseases causing CP are not restricted to the pericardium but also infiltrate the biventricular myocardium and affect the thin-walled RV more than the thick-walled LV, resulting in depressed RVsf. The present results help explain clinical heart failure in the presence of restricted diastolic filling in CP. Depression of RVsf due to progression of fibrosis in the RV myocardium may increase the risk of delayed pericardiectomy.

Racial disparities in utilization and outcomes of mechanical circulatory support (MCS) in patients with acute myocardial infarction-cardiogenic shock (AMI-CS) are infrequently studied. This study sought to evaluate racial disparities in the outcomes of MCS in AMI-CS. The National Inpatient Sample (2012-2017) was used to identify adult AMI-CS admissions receiving MCS support. MCS devices were classified as intra-aortic balloon pump (IABP), percutaneous left ventricular assist device (pLVAD) or extracorporeal membrane oxygenation (ECMO). Self-reported race was classified as white, black and others. Outcomes included in-hospital mortality, hospital length of stay and discharge disposition. During this period, 90,071 admissions were included with white, black and other races constituting 73.6%, 8.3% and 18.1%, respectively. Compared to white and other races, black race admissions were on average younger, female, with greater comorbidities, and non-cardiac organ failure (all p < 0.001). Compared to the white race (31.3%), in-hospital mortality was comparable in black (31.4%; adjusted odds ratio (aOR) 0.98 (95% confidence interval (CI) 0.93-1.05); p = 0.60) and other (30.2%; aOR 0.96 (95% CI 0.92-1.01); p = 0.10). Higher in-hospital mortality was noted in non-white races with concomitant cardiac arrest, and those receiving ECMO support. Black admissions had longer lengths of hospital stay (12.1 ± 14.2, 10.3 ± 11.2, 10.9 ± 1.2 days) and transferred less often (12.6%, 14.2%, 13.9%) compared to white and other races (both p < 0.001). In conclusion, this study of AMI-CS admissions receiving MCS devices did not identify racial disparities in in-hospital mortality. Black admissions had longer hospital stay and were transferred less often. Further evaluation with granular data including angiographic and hemodynamic parameters is essential to rule out racial differences.
RESUMEN
Transcatheter aortic valve replacement (TAVR) is a safe and feasible alternative to surgery in patients with symptomatic severe aortic stenosis regardless of the surgical risk. Conduction abnormalities requiring permanent pacemaker (PPM) implantation remain a common finding after TAVR due to the close proximity of the atrioventricular conduction system to the aortic root. High-grade atrioventricular block and new onset left bundle branch block (LBBB) are the most commonly reported conduction abnormalities after TAVR. The overall rate of PPM implantation after TAVR varies and is related to pre-procedural and intraprocedural factors. The available literature regarding the impact of conduction abnormalities and PPM requirement on morbidity and mortality is still conflicting. Pre-procedural conduction abnormalities such as right bundle branch block and LBBB have been linked with increased PPM implantation and mortality after TAVR. When screening patients for TAVR, heart teams should be aware of various anatomical and pathophysiological conditions that make patients more susceptible to increased risk of conduction abnormalities and PPM requirement after the procedure. This is particularly important as TAVR has been recently approved for patients with low surgical risk. The purpose of this review is to discuss the incidence, predictors, impact, and management of the various conduction abnormalities requiring PPM implantation in patients undergoing TAVR.

OBJECTIVE: Patients with constrictive pericarditis (CP) with active inflammation may show resolution with anti-inflammatory therapy. We aimed to investigate the impact of anti-inflammatory medications on constrictive pathophysiology using echocardiography in patients with CP. METHODS: We identified 35 patients with CP who were treated with anti-inflammatory medications (colchicine, prednisone, non-steroidal anti-inflammatory drugs) after diagnosis of CP (mean age 58±13; 80% male). Clinical resolution of CP (transient CP) was defined as improvement in New York Heart Association class during follow-up. We assessed constrictive pathophysiology using regional myocardial mechanics by the ratio of peak early diastolic tissue velocity (e') at the lateral and septal mitral annulus by tissue Doppler imaging (lateral/septal e') or the ratio of the left ventricular lateral and septal wall longitudinal strain (LSlateral/LSseptal) by two-dimensional speckle-tracking echocardiography. Longitudinal data were analysed using a mixed effects model. RESULTS: During a median follow-up of 323 days, 20 patients had transient CP, whereas 15 patients had persistent CP. Transient CP had higher baseline erythrocyte sedimentation rates (ESR) (p=0.003) compared with persistent CP. There were no significant differences in LSlateral/LSseptal and lateral/septal e'. During follow-up, only transient CP showed improvement in lateral/septal e' (p<0.001) and LSlateral/LSseptal (p=0.003), and recovery of inflammatory markers was similar between the two groups. In the logistic model, higher baseline ESR and greater improvement in lateral/septal e' and LSlateral/LSseptal were associated with clinical resolution of CP using anti-inflammatory therapy. CONCLUSIONS: Improvement of constrictive physiology detected by lateral/septal e' and LSlateral/LSseptal was associated with resolution of clinical symptoms after anti-inflammatory treatment. Serial monitoring of these markers could be used to identify transient CP.

BACKGROUND: The conventional method of implanting balloon-expandable SAPIEN-3 (S3) valve results in a final 70:30 or 80:20 ratio of the valve in the aorta:left ventricular outflow tract with published rates of permanent pacemaker around 10%. We sought to evaluate whether higher implantation of S3 reduces conduction abnormalities including the need for permanent pacemaker. METHODS: We included consecutive patients who underwent transfemoral transcatheter aortic valve replacement using S3 between April 2015 and December 2018 and compared outcomes with typical valve deployment strategy to our more contemporary high deployment technique (HDT). We excluded patients with nontransfemoral access or valve-in-valve. RESULTS: Among 1028 patients, HDT was performed in 406 patients (39.5%). Mean implantation depth under the noncoronary cusp was significantly smaller with HDT compared with conventional technique (1.5±1.6 versus 3.2±1.9 mm; P<0.001). Successful implantation was achieved in 100% of the patients in both groups with no cases of conversion to open heart surgery, second valve implantation within the first transcatheter aortic valve replacement, or coronary occlusion during transcatheter aortic valve replacement. One patient (0.2%) had valve embolization with HDT (P=0.216). Thirty-day permanent pacemaker rates were lower with HDT (5.5% versus 13.1%; P<0.001), as were rates of complete heart block (3.5% versus 11.2%; P<0.001) and new-onset left bundle branch block (5.3% versus 12.2%; P<0.001). There were no differences in mild (16.5% versus 15.9%; P=0.804), or moderate-to-severe aortic regurgitation (1% versus 2.7%; P=0.081) at 1 year. HDT was associated with slightly higher 1-year mean gradients (13.1±6.2 versus 11.8±4.9 mm Hg; P=0.042) and peak gradients (25±11.9 versus 22.5±9 mm Hg; P=0.026). However, Doppler velocity index was similar (0.47±0.15 versus 0.48±0.13; P=0.772). CONCLUSIONS: Our novel technique for balloon-expandable S3 valve positioning consistently achieves higher implantation resulting in substantial reduction in conduction abnormalities and permanent pacemaker requirement after transcatheter aortic valve replacement without compromising procedural safety or valve hemodynamics. Operators should consider this as an important technique to improve patient outcomes.

BACKGROUND: There is a paucity of data regarding the optimum timing of PCI in relation to TAVR. OBJECTIVE: We compared the major adverse cardiovascular and cerebrovascular events (MACCE) rates among patients who underwent percutaneous coronary intervention (PCI) before transcatheter aortic valve replacement (TAVR) with those who received PCI with/after TAVR. METHODS: In this multicenter study, we pooled all consecutive patients who underwent TAVR at three high volume centers. RESULTS: Among 3,982 patients who underwent TAVR, 327 (8%) patients underwent PCI within 1 year before TAVR, 38 (1%) had PCI the same day as TAVR and 15 (0.5%) had PCI within 2 months after TAVR. Overall, among patients who received both PCI and TAVR (n = 380), history of previous CABG (HR:0.501; p = .001), higher BMI at TAVR (HR:0.970; p = .038), and statin therapy after TAVR (HR:0.660, p = .037) were independently associated with lower MACCE while warfarin therapy after TAVR was associated with a higher risk of MACCE (HR:1.779, p = .017). Patients who received PCI within 1 year before TAVR had similar baseline demographics, STS scores, clinical risk factors when compared to patients receiving PCI with/after TAVR. Both groups were similar in PCI (Syntax Score, ACC/AHA lesion class) and TAVR (valve types, access) related variables. There were no significant differences in terms of MACCE (log rank p = .550), all-cause mortality (log rank p = .433), strokes (log rank p = .153), and repeat PCI (log rank p = .054) in patients who underwent PCI with/after TAVR when compared to patients who received PCI before TAVR. CONCLUSION: Among patients who underwent both PCI and TAVR, history of CABG, higher BMI, and statin therapy had lower, while those discharged on warfarin, had higher adverse event rates. Adverse events rates were similar regardless of timing of PCI.

BACKGROUND: Baseline conduction abnormalities are known risk factors for permanent pacemaker (PPM) implantation after transcatheter aortic valve replacement (TAVR). We sought to determine the impact of baseline right bundle branch block (RBBB), left bundle branch block (LBBB), left anterior hemiblock (LAHB), first-degree atrioventricular block (AVB) and atrial fibrillation/flutter (AF) on TAVR outcomes. METHODS: Consecutive patients who underwent transfemoral TAVR with SAPIEN-3 (S3) were included. We excluded patients with prior PPM, nontransfemoral access or valve-in-valve. RESULTS: Among 886 patients, baseline RBBB was seen in 15.9%, LBBB in 6.3%, LAHB in 6.2%, first-degree AVB in 26.3% and AF in 37.5%. The rate of 30-day PPM was 10.1%. Baseline RBBB (OR 4.005; 95% CI 2.386-6.723; p < .001) and first-degree AVB (OR 1.847; 95% CI 1.133-3.009; p = .014) were independent predictors of 30 day PPM. LAHB also resulted in higher PPM rates but only in unadjusted analysis (21.8% vs. 9.4%; p = .003). Baseline LBBB and AF were associated with lower left ventricular ejection fraction (LVEF) at both baseline and 1 year after TAVR. However, Δ LVEF over time were noted to be similar with baseline LBBB (1.8% vs. 1.4%; p = .809) and AF (1.1% vs. 1.7%; p = .458). Moreover, baseline AF was also associated with higher stroke/transient ischemic attack (TIA) at 1 year (4.4% vs. 1.8%; p = .019), 1-year major adverse cardiac and cerebrovascular events (MACCE) (19.5% vs. 13.3%; p = .012) and 2 year mortality (23.5% vs. 15.2%; p = .016). None of the other baseline conduction defects affected long-term mortality or MACCE. CONCLUSION: In our S3 TAVR population, baseline RBBB and first-degree AVB predicted higher PPM risk. Prior LBBB and AF were associated with lower LVEF at both baseline and 1 year. Lastly, preexisting AF was associated with higher rates of mortality, stroke/TIA, and MACCE.

Background The ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) trial failed to show a reduction in hard clinical end points with an early invasive strategy in stable ischemic heart disease (SIHD). However, the influence of left main disease and high-risk coronary anatomy was left unaddressed. In a large angiographic disease-based registry, we examined the modulating effect of revascularization on long-term outcomes in anatomically high-risk SIHD. Methods and Results 9016 patients with SIHD with high-risk coronary anatomy (3 vessel disease with ≥70% stenosis in all 3 epicardial vessels or left main disease ≥50% stenosis [isolated or in combination with other disease]) were selected for study from April 1, 2002 to March 31, 2016. The primary composite of all-cause death or myocardial infarction (MI) was compared between revascularization versus conservative management. A total of 5487 (61.0%) patients received revascularization with either coronary artery bypass graft surgery (n=3312) or percutaneous coronary intervention (n=2175), while 3529 (39.0%) patients were managed conservatively. Selection for coronary revascularization was associated with improved all-cause death/MI as well as longer survival compared with selection for conservative management (Inverse Probability Weighted hazard ratio [IPW-HR] 0.62; 95% CI 0.58 to 0.66; P<0.001; IPW-HR 0.57; 95% CI 0.53-0.61; P<0.001, respectively). Similar risk reduction was noted with percutaneous coronary intervention (IPW-HR 0.64, 95% CI 0.59-0.70, P<0.001) and coronary artery bypass graft surgery (IPW-HR 0.61; 95% CI 0.57-0.66; P<0.001). Conclusions Revascularization in patients with SIHD with high-risk coronary anatomy was associated with improved long-term outcome compared with conservative therapy. As such, coronary anatomical profile should be considered when contemplating treatment for SIHD.

Transradial access (TRA) has emerged as an alternative to transfemoral access (TFA) for percutaneous coronary intervention (PCI) in ST elevation myocardial infarction (STEMI) patients. However, the rate of TRA adoption has been much slower in the acute coronary syndrome (ACS) patient population. This meta-analysis was conducted to assess clinical outcomes of TRA compared with TFA in STEMI patients undergoing PCI. A manual search of PubMed, EMBASE, Cochrane library database, Cumulative Index to Nursing and Allied Health Literature (CINAHL), ClinicalTrials.gov, and recent major scientific conference sessions from inception to October 15th, 2019 was performed. Primary outcomes in our analysis were all-cause mortality and trial-defined major bleeding. Secondary outcomes included vascular complications, myocardial infarction, stroke, procedure, and fluoroscopy time. 17 randomized controlled trials (RCTs) (Nâ¯=â¯12,018) met inclusion criteria. TRA was associated with lower all-cause mortality (risk ratio [RR]: 0.71, 95% confidence interval [CI]: 0.57 to 0.88), major bleeding (RR: 0.59, 95%CI: 0.45 to 0.77), and vascular complications (RR: 0.42, 95%CI: 0.32 to 0.56) compared with TFA. There was no difference in the incidence of myocardial infarction (MI), stroke, or procedure duration between the 2 groups. The difference in all-cause mortality between TRA and TFA was statistically nonsignificant when major bleeding was held constant. In conclusion, TRA was associated with lower risk of all-cause mortality, major bleeding, and vascular complications compared with TFA in STEMI patients undergoing PCI.
