RESUMEN
INTRODUCTION AND OBJECTIVES: In patients undergoing percutaneous coronary intervention (PCI) in the workup pre-transcatheter aortic valve replacement (TAVR), the clinical impact of coronary revascularization complexity remains unknown. This study sought to examine the impact of PCI complexity on clinical outcomes after TAVR in patients undergoing PCI in the preprocedural workup. METHODS: This was a multicenter study including consecutive patients scheduled for TAVR with concomitant significant coronary artery disease. Complex PCI was defined as having at least 1 of the following features: 3 vessels treated, ≥ 3 stents implanted, ≥ 3 lesions treated, bifurcation with 2 stents implanted, total stent length >60mm, or chronic total occlusion. The rates of major adverse cardiac events (MACE), including cardiovascular mortality, myocardial infarction, and coronary revascularization were evaluated. RESULTS: A total of 1550 patients were included, of which 454 (29.3%) underwent complex PCI in the pre-TAVR workup. After a median follow-up period of 2 [1-3] years after TAVR, the incidence of MACE was 9.6 events per 100 patients-years. Complex PCI significantly increased the risk of cardiac death (HR, 1.44; 95%CI, 1.01-2.07), nonperiprocedural myocardial infarction (HR, 1.52; 95%CI, 1.04-2.21), and coronary revascularization (HR, 2.46; 95%CI, 1.44-4.20). In addition, PCI complexity was identified as an independent predictor of MACE after TAVR (HR, 1.31; 95%CI, 1.01-1.71; P=.042). CONCLUSIONS: In TAVR candidates with significant coronary artery disease requiring percutaneous treatment, complex revascularization was associated with a higher risk of MACE. The degree of procedural complexity should be considered a strong determinant of prognosis in the PCI-TAVR population.
RESUMEN
BACKGROUND: The optimal treatment in patients with severe aortic stenosis and small aortic annulus (SAA) remains to be determined. This study aimed to compare the hemodynamic and clinical outcomes between transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) in patients with a SAA. METHODS: This prospective multicenter international randomized trial was performed in 15 university hospitals. Participants were 151 patients with severe aortic stenosis and SAA (mean diameter <23 mm) randomized (1:1) to TAVR (n=77) versus SAVR (n=74). The primary outcome was impaired valve hemodynamics (ie, severe prosthesis patient mismatch or moderate-severe aortic regurgitation) at 60 days as evaluated by Doppler echocardiography and analyzed in a central echocardiography core laboratory. Clinical events were secondary outcomes. RESULTS: The mean age of the participants was 75.5±5.1 years, with 140 (93%) women, a median Society of Thoracic Surgeons predicted risk of mortality of 2.50% (interquartile range, 1.67%-3.28%), and a median annulus diameter of 21.1 mm (interquartile range, 20.4-22.0 mm). There were no differences between groups in the rate of severe prosthesis patient mismatch (TAVR, 4 [5.6%]; SAVR, 7 [10.3%]; P=0.30) and moderate-severe aortic regurgitation (none in both groups). No differences were found between groups in mortality rate (TAVR, 1 [1.3%]; SAVR, 1 [1.4%]; P=1.00) and stroke (TAVR, 0; SAVR, 2 [2.7%]; P=0.24) at 30 days. After a median follow-up of 2 (interquartile range, 1-4) years, there were no differences between groups in mortality rate (TAVR, 7 [9.1%]; SAVR, 6 [8.1%]; P=0.89), stroke (TAVR, 3 [3.9%]; SAVR, 3 [4.1%]; P=0.95), and cardiac hospitalization (TAVR, 15 [19.5%]; SAVR, 15 [20.3%]; P=0.80). CONCLUSIONS: In patients with severe aortic stenosis and SAA (women in the majority), there was no evidence of superiority of contemporary TAVR versus SAVR in valve hemodynamic results. After a median follow-up of 2 years, there were no differences in clinical outcomes between groups. These findings suggest that the 2 therapies represent a valid alternative for treating patients with severe aortic stenosis and SAA, and treatment selection should likely be individualized according to baseline characteristics, additional anatomical risk factors, and patient preference. However, the results of this study should be interpreted with caution because of the limited sample size leading to an underpowered study, and need to be confirmed in future larger studies.

INTRODUCTION AND OBJECTIVES: There are scarce data on the factors associated with impaired functional status after transcatheter aortic valve replacement (TAVR) and its clinical impact. This study aimed to determine the incidence, predictors, and prognostic implications of impaired functional class (NYHA class III-IV) following TAVR. METHODS: This multicenter study included 3462 transarterial TAVR patients receiving newer generation devices. The patients were compared according to their NYHA class at 1 month of follow-up (NYHA I-II vs NYHA III-IV). A multivariate logistic regression was performed to identify the predictors of 30-day NYHA class III-IV. Patient survival was compared with the Kaplan-Meier method and factors associated with decreased survival were identified with Cox regression analysis. RESULTS: The mean age of the study population was 80.3±7.3 years, with 47% of women, and a median Society of Thoracic Surgeons score of 3.8% [IQR, 2.5-5.8]. A total of 208 patients (6%) were in NYHA class III-IV 1 month after TAVR. Predictors of 30-day NYHA class III-IV were baseline NYHA class III-IV (OR, 1.76; 95%CI, 1.08-2.89; P=.02), chronic pulmonary obstructive disease (OR, 1.80; 95%CI, 1.13-2.83; P=.01), and post-TAVR severe mitral regurgitation (OR, 2.00; 95%CI, 1.21-3.31; P<.01). Patients in NYHA class III-IV 1 month after TAVR were at higher risk of death (HR, 3.68; 95%CI, 2.39-5.70; P<.01) and heart failure-related hospitalization (HR, 6.00; 95%CI, 3.76-9.60; P<.01) at 1-year follow-up. CONCLUSIONS: Up to 6% of contemporary TAVR patients exhibited an impaired functional status following TAVR. Worse baseline NYHA class, chronic pulmonary obstructive disease, and severe mitral regurgitation predicted 30-day NYHA class III/IV, and this determined a higher risk of mortality and heart failure hospitalization at 1-year follow-up. Further studies on the prevention and treatment optimization of patients with impaired functional status after TAVR are needed.
RESUMEN
BACKGROUND: The SavvyWire (OpSens Inc) is a 0.035-inch preshaped guidewire with dedicated pacing properties and a distal pressure sensor allowing for continuous hemodynamic pressure monitoring. OBJECTIVES: This study sought to determine the efficacy and safety of the guidewire during transcatheter aortic valve replacement (TAVR) procedures. METHODS: This prospective, multicenter clinical study included patients with severe aortic stenosis undergoing TAVR in 8 European centers. The primary efficacy endpoint was defined as effective left ventricular rapid pacing runs with the guidewire translating into a significant systemic pressure drop (below 60 mm Hg). The safety outcome included the absence of major procedural complications related to the guidewire. RESULTS: A total of 121 patients (mean age: 82.2 ± 5.9 years, 50% women) were included in the study, and 119 (98.3%) patients were finally treated with the study device. A balloon-expandable valve was implanted in 45 (37.8%) patients. Predilatation and postdilatation were performed in 89 (74.8%) and 14 (11.8%) patients, respectively. The primary efficacy endpoint was achieved in 116 (98.3%) patients, and the mean aortic systolic arterial pressure achieved during rapid pacing was 46.6 ± 11.3 mm Hg. Hemodynamic assessment with the use of the OptoMonitor 3 (OpSens Inc) without additional catheter exchange was achieved in 117 (99.2%) patients. The safety endpoint was achieved in 117 (99.2%) patients. No procedural mortality, stroke, or ventricular perforation was reported. CONCLUSIONS: The use of the guidewire during TAVR procedures appeared to be efficacious and safe. This device could help minimize interventions during the procedure and improve the clinical decision making after transcatheter heart valve deployment.

BACKGROUND: In patients undergoing percutaneous coronary intervention (PCI) in the work-up pre-transcatheter aortic valve replacement (TAVR), the incidence and clinical impact of late bleeding events (LBEs) remain largely unknown. OBJECTIVES: This study sought to determine the incidence, clinical characteristics, associated factors, and outcomes of LBEs in patients undergoing PCI in the work-up pre-TAVR. METHODS: This was a multicenter study including 1,457 consecutive patients (mean age 81 ± 7 years; 41.5% women) who underwent TAVR and survived beyond 30 days. LBEs (>30 days post-TAVR) were defined according to the Valve Academic Research Consortium-2 criteria. RESULTS: LBEs occurred in 116 (7.9%) patients after a median follow-up of 23 (IQR: 12-40) months. Late bleeding was minor, major, and life-threatening or disabling in 21 (18.1%), 63 (54.3%), and 32 (27.6%) patients, respectively. Periprocedural (<30 days post-TAVR) major bleeding and the combination of antiplatelet and anticoagulation therapy at discharge were independent factors associated with LBEs (P ≤ 0.02 for all). LBEs conveyed an increased mortality risk at 4-year follow-up compared with no bleeding (43.9% vs 36.0; P = 0.034). Also, LBE was identified as an independent predictor of all-cause mortality after TAVR (HR: 1.39; 95% CI: 1.05-1.83; P = 0.020). CONCLUSIONS: In TAVR candidates with concomitant significant coronary artery disease requiring percutaneous treatment, LBEs after TAVR were frequent and associated with increased mortality. Combining antiplatelet and anticoagulation regimens and the occurrence of periprocedural bleeding determined an increased risk of LBEs. Preventive strategies should be pursued for preventing late bleeding after TAVR, and further studies are needed to provide more solid evidence on the most safe and effective antithrombotic regimen post-TAVR in this challenging group of patients.

BACKGROUND: The burden of cardiac death after transcatheter aortic valve replacement (TAVR), particularly from advanced heart failure (HF) and sudden cardiac death (SCD), remains largely unknown. OBJECTIVES: This study sought to evaluate the incidence and predictors of SCD and HF-related death in TAVR recipients treated with newer-generation devices. METHODS: This study included a total of 5,421 consecutive patients who underwent TAVR with newer-generation devices using balloon (75.7%) or self-expandable (24.3%) valves. RESULTS: After a median follow-up of 2 (IQR: 1-3) years, 976 (18.0%) patients had died, 50.8% from cardiovascular causes. Advanced HF and SCD accounted for 11.6% and 7.5% of deaths, respectively. Independent predictors of HF-related death were atrial fibrillation (HR: 2.17; 95% CI: 1.47-3.22; P < 0.001), prior pacemaker (HR: 1.79; 95% CI: 1.10-2.92; P = 0.01), reduced left ventricular ejection fraction (HR: 1.08 per 5% decrease; 95% CI: 1.01-1.14; P = 0.02), transthoracic approach (HR: 2.50; 95% CI: 1.37-4.55; P = 0.003), and new-onset persistent left bundle branch block (HR: 1.85; 95% CI: 1.14-3.02; P = 0.01). Two baseline characteristics (diabetes, HR: 1.81; 95% CI: 1.13-2.89; P = 0.01; and chronic kidney disease, HR: 1.72; 95% CI: 1.02-2.90; P = 0.04) and 3 procedural findings (valve in valve, HR: 2.17; 95% CI: 1.01-4.64; P = 0.04; transarterial nontransfemoral approach, HR: 2.23; 95% CI: 1.23-4.48; P = 0.01; and periprocedural ventricular arrhythmia, HR: 7.19; 95% CI: 2.61-19.76; P < 0.001) were associated with an increased risk of SCD after TAVR. CONCLUSIONS: Advanced HF and SCD accounted for a fifth of deaths after TAVR in contemporary practice. Potentially treatable factors leading to increased risk of HF deaths and SCD were identified, such as arrhythmia/dyssynchrony factors for HF and valve-in-valve TAVR or periprocedural ventricular arrhythmias for SCD.

BACKGROUND: The potential benefit of using larger or smaller transcatheter heart valves (THV) in patients with borderline aortic annulus measurement (BAM) remains uncertain. The objective of this study was to evaluate the clinical outcomes associated with the selection of larger or smaller THV in the context of BAM. METHODS: This was a multicenter observational study including patients who underwent transcatheter aortic valve replacement with the SAPIEN 3 or SAPIEN 3 Ultra-valve systems (Edwards Lifesciences, Irvine, CA) from April 2014 to June 2021. BAM was defined according to the manufacturer sizing chart and included the following annulus areas: 314 to 346, 400 to 430, 500 to 546 mm2. A 1:1 propensity score matching was used to compare outcomes of patients with larger or smaller THV. RESULTS: From a total of 2467 patients, BAM was identified in 852 patients (34.5%). A larger and smaller THV was selected in 338 (39.7%) and 514 patients (60.3%) patients, respectively. The choice of a larger THV was associated (before and after propensity matching) with a higher risk of new-onset left bundle branch block (HR, 2.25 [95% CI, 1.39-3.65; P=0.001) and permanent pacemaker implantation (HR, 1.86 [95% CI, 1.11-3.09]; P=0.016) without any impact on gradients or the risk of moderate or severe paravalvular regurgitation at discharge (HR, 0.78 [95% CI, 0.41-1.45]; P=0.427). The risk of periprocedural complications such as aortic rupture and tamponade was low (<1%) and similar between groups. CONCLUSIONS: In patient with BAM, selecting a larger SAPIEN 3/Ultra THV increased the risk of conduction disturbances without any benefit on valve hemodynamics and clinical outcomes.

This paper describes an empirical study carried out with 40 Spanish deaf people, users of sign language, between 19 and 45 years of age, which gathers their perceptions of aspects related to the incidence of the COVID-19 pandemic and its repercussions. During the pandemic, people with hearing disabilities, among other groups, were forgotten. They suffered from accessibility problems to the information issued by the authorities, violating their right to be informed and exposing their health to COVID-19. In this work, we identify the problems they suffered and what effects COVID-19 had on their lives. This will help to take the appropriate measures to restore their rights and design policies and strategies to deal with any new future health emergency. For this, an ad hoc questionnaire was designed, adapted to easy reading and sign language. This was publicized via email and WhatsApp through the Association of Deaf People of Granada and Province (Spain) and was responded to online and by video call with the collaboration of sign language interpreters using the LimeSurvey platform. The results discover (1) the difficulties of communication barriers in the relationship with health professionals and institutions, as well as in the spheres of work and education, (2) similarities with the rest of the population in the negative effects of confinement, and (3) presence of positive effects, such as the development of positive activities and emotions. The study highlights the need to increase economic and institutional support aimed at improving coping resources, access to information, and the reduction of social and institutional barriers that would allow people with hearing disabilities to successfully face future health problems of a global nature such as that experienced with COVID-19.

This study seeks to know if there is a relationship between measures of suicidal ideation and cognitive orientation towards spirituality, religious attitudes and beliefs, and religious practice. A non-experimental, descriptive, and correlational design, cross-sectional and quantitative approach was used. The sample was made up of 1372 adolescents, 59.2% female, 40.8% male, mean age 14.57, s = 1.75, range 12-17 years old, students from public schools in two cities in Colombia. The results indicated an inverse relationship between negative suicidal ideation (NSI) and cognitive orientation towards spirituality, beliefs and attitudes, and religious practice, and a positive relationship between them and positive suicidal ideation. The regression analysis showed the contribution of spirituality, religious beliefs, and attitudes in the prediction of NSI. In conclusion, the dimensions of spirituality and religiosity can help reduce suicidal thinking, acting as protective factors. The cultivation of a spiritual and/or religious life can be suitable and complementary ways as measures of prevention of suicidal behaviour.
RESUMEN
BACKGROUND: Morbidly obese (MO) patients are increasingly undergoing transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) for severe aortic stenosis (AS). However, the best therapeutic strategy for these patients remains a matter for debate. AIMS: Our aim was to compare the periprocedural and mid-term outcomes in MO patients undergoing TAVR versus SAVR. METHODS: A multicentre retrospective study including consecutive MO patients (body mass index ≥40 kg/m2, or ≥35 kg/m2 with obesity-related comorbidities) from 18 centres undergoing either TAVR (n=860) or biological SAVR (n=696) for severe AS was performed. Propensity score matching resulted in 362 pairs. RESULTS: After matching, periprocedural complications, including blood transfusion (14.1% versus 48.1%; p<0.001), stage 2-3 acute kidney injury (3.99% versus 10.1%; p=0.002), hospital-acquired pneumonia (1.7% versus 5.8%; p=0.005) and access site infection (1.5% versus 5.5%; p=0.013), were more common in the SAVR group, as was moderate to severe patient-prosthesis mismatch (PPM; 9.9% versus 39.4%; p<0.001). TAVR patients more frequently required permanent pacemaker implantation (14.4% versus 5.6%; p<0.001) and had higher rates of ≥moderate residual aortic regurgitation (3.3% versus 0%; p=0.001). SAVR was an independent predictor of moderate to severe PPM (hazard ratio [HR] 1.80, 95% confidence interval [CI]: 1.25-2.59; p=0.002), while TAVR was not. In-hospital mortality was not different between groups (3.9% for TAVR versus 6.1% for SAVR; p=0.171). Two-year outcomes (including all-cause and cardiovascular mortality, and readmissions) were similar in both groups (log-rank p>0.05 for all comparisons). Predictors of all-cause 2-year mortality differed between the groups; moderate to severe PPM was a predictor following SAVR (HR 1.78, 95% CI: 1.10-2.88; p=0.018) but not following TAVR (p=0.737). CONCLUSIONS: SAVR and TAVR offer similar mid-term outcomes in MO patients with severe AS, however, TAVR offers some advantages in terms of periprocedural morbidity.

OBJECTIVES: The aim of this study was to compare, in a cohort of patients with complex coronary artery disease (CAD) and severe aortic stenosis (AS), the clinical outcomes associated with transfemoral transcatheter aortic valve replacement (TAVR) (plus percutaneous coronary intervention [PCI]) versus surgical aortic valve replacement (SAVR) (plus coronary artery bypass grafting [CABG]). BACKGROUND: Patients with complex CAD were excluded from the main randomized trials comparing TAVR with SAVR, and no data exist comparing TAVR + PCI vs SAVR + CABG in such patients. METHODS: A multicenter study was conducted including consecutive patients with severe AS and complex CAD (SYNTAX [Synergy Between PCI with Taxus and Cardiac Surgery] score >22 or unprotected left main disease). A 1:1 propensity-matched analysis was performed to account for unbalanced covariates. The rates of major adverse cardiac and cerebrovascular events (MACCE), including all-cause mortality, nonprocedural myocardial infarction, need for new coronary revascularization, and stroke, were evaluated. RESULTS: A total of 800 patients (598 undergoing SAVR + CABG and 202 undergoing transfemoral TAVR + PCI) were included, and after propensity matching, a total of 156 pairs of patients were generated. After a median follow-up period of 3 years (interquartile range: 1-6 years), there were no significant differences between groups for MACCE (HR for transfemoral TAVR vs SAVR: 1.33; 95% CI: 0.89-1.98), all-cause mortality (HR: 1.25; 95% CI: 0.81-1.94), myocardial infarction (HR: 1.16; 95% CI: 0.41-3.27), and stroke (HR: 0.42; 95% CI: 0.13-1.32), but there was a higher rate of new coronary revascularization in the TAVR + PCI group (HR: 5.38; 95% CI: 1.73-16.7). CONCLUSIONS: In patients with severe AS and complex CAD, TAVR + PCI and SAVR + CABG were associated with similar rates of MACCE after a median follow-up period of 3 years, but TAVR + PCI recipients exhibited a higher risk for repeat coronary revascularization. Future trials are warranted.

BACKGROUND: Vascular and bleeding complications related to secondary femoral access site are frequent in patients undergoing transcatheter aortic valve replacement (TAVR), and their occurrence is associated to poorer outcomes. We aimed to evaluate the clinical impact of vascular closure devices (VCDs) for secondary femoral access hemostasis in TAVR procedures. METHODS: This was a multicenter study including 4031 patients who underwent TAVR (mean age, 81 ± 8 years; mean Society of Thoracic Surgeons [STS] score, 4.9 [interquartile range, 3.3-7.6]), and had a secondary femoral access. The 30-day clinical outcomes were analyzed according to femoral access-site hemostasis (manual compression vs VCD), and according to the type of VCD (Perclose [Abbott Cardiovascular] vs Angio-Seal [Terumo Interventional Systems]) using a propensity-matched, multivariable, logistic regression model. RESULTS: Manual compression was used in 941 patients (23.3%) and VCDs were used in 3090 patients (76.7%; Perclose in 1549 patients [38.4%] and Angio-Seal in 1541 patients [38.2%]) for secondary femoral access hemostasis. Vascular complications related to secondary access site occurred in 162 patients (4%), and were more frequent in patients who underwent manual compression (7.2%) compared with VCD hemostasis (3%; adjusted P<.001). In the VCD group, the use of Angio-Seal (vs Perclose) was associated with a higher rate of vascular complications (3.7% vs 2.4%, respectively; adjusted P=.02), femoral artery pseudoaneurysm (1.3% vs 0.4%, respectively; adjusted P<.01), invasive treatment requirement for treating vascular complications (surgery: 0.8% vs 0.3%, respectively [adjusted P=.03]; and thrombin injection: 0.9% vs 0%, respectively [adjusted P<.001]). CONCLUSION: VCDs represented a safer and more effective alternative compared with manual compression for secondary femoral access-site hemostasis in patients undergoing TAVR procedures, and the Perclose VCD was associated with the lowest risk of vascular complications. Future randomized studies are warranted.

Background There is a paucity of outcome data on patients who are morbidly obese (MO) undergoing transcatheter aortic valve replacement. We aimed to determine their periprocedural and midterm outcomes and investigate the impact of obesity phenotype. Methods and Results Consecutive patients who are MO (body mass index, ≥40 kg/m2, or ≥35 kg/m2 with obesity-related comorbidities; n=910) with severe aortic stenosis who underwent transcatheter aortic valve replacement in 18 tertiary hospitals were compared with a nonobese cohort (body mass index, 18.5-29.9 kg/m2, n=2264). Propensity-score matching resulted in 770 pairs. Pre-transcatheter aortic valve replacement computed tomography scans were centrally analyzed to assess adipose tissue distribution; epicardial, abdominal visceral and subcutaneous fat. Major vascular complications were more common (6.6% versus 4.3%; P=0.043) and device success was less frequent (84.4% versus 88.1%; P=0.038) in the MO group. Freedom from all-cause and cardiovascular mortality were similar at 2 years (79.4 versus 80.6%, P=0.731; and 88.7 versus 87.4%, P=0.699; MO and nonobese, respectively). Multivariable analysis identified baseline glomerular filtration rate and nontransfemoral access as independent predictors of 2-year mortality in the MO group. An adverse MO phenotype with an abdominal visceral adipose tissue:subcutaneous adipose tissue ratio ≥1 (VAT:SAT) was associated with increased 2-year all-cause (hazard ratio [HR], 3.06; 95% CI, 1.20-7.77; P=0.019) and cardiovascular (hazard ratio, 4.11; 95% CI, 1.06-15.90; P=0.041) mortality, and readmissions (HR, 1.81; 95% CI, 1.07-3.07; P=0.027). After multivariable analysis, a (VAT:SAT) ratio ≥1 remained a strong predictor of 2-year mortality (hazard ratio, 2.78; P=0.035). Conclusions Transcatheter aortic valve replacement in patients who are MO has similar short- and midterm outcomes to nonobese patients, despite higher major vascular complications and lower device success. An abdominal VAT:SAT ratio ≥1 identifies an obesity phenotype at higher risk of adverse clinical outcomes.

BACKGROUND: Among patients with acute coronary syndrome following transcatheter aortic valve replacement (TAVR), those presenting with ST-segment elevation myocardial infarction (STEMI) are at highest risk. OBJECTIVES: The goal of this study was to determine the clinical characteristics, management, and outcomes of STEMI after TAVR. METHODS: This was a multicenter study including 118 patients presenting with STEMI at a median of 255 days (interquartile range: 9 to 680 days) after TAVR. Procedural features of STEMI after TAVR managed with primary percutaneous coronary intervention (PCI) were compared with all-comer STEMI: 439 non-TAVR patients who had primary PCI within the 2 weeks before and after each post-TAVR STEMI case in 5 participating centers from different countries. RESULTS: Median door-to-balloon time was higher in TAVR patients (40 min [interquartile range: 25 to 57 min] vs. 30 min [interquartile range: 25 to 35 min]; p = 0.003). Procedural time, fluoroscopy time, dose-area product, and contrast volume were also higher in TAVR patients (p < 0.01 for all). PCI failure occurred more frequently in patients with previous TAVR (16.5% vs. 3.9%; p < 0.001), including 5 patients in whom the culprit lesion was not revascularized owing to coronary ostia cannulation failure. In-hospital and late (median of 7 months [interquartile range: 1 to 21 months]) mortality rates were 25.4% and 42.4%, respectively (20.6% and 38.2% in primary PCI patients), and estimated glomerular filtration rate <60 ml/min (hazard ratio [HR]: 3.02; 95% confidence interval [CI]: 1.42 to 6.43; p = 0.004), Killip class ≥2 (HR: 2.74; 95% CI: 1.37 to 5.49; p = 0.004), and PCI failure (HR: 3.23; 95% CI: 1.42 to 7.31; p = 0.005) determined an increased risk. CONCLUSIONS: STEMI after TAVR was associated with very high in-hospital and mid-term mortality. Longer door-to-balloon times and a higher PCI failure rate were observed in TAVR patients, partially due to coronary access issues specific to the TAVR population, and this was associated with poorer outcomes.

BACKGROUND: Procedural improvements combined with the contemporary clinical profile of patients undergoing transcatheter aortic valve replacement (TAVR) may have influenced the incidence and outcomes of infective endocarditis (IE) following TAVR. We aimed to determine the temporal trends, characteristics, and outcomes of IE post-TAVR. METHODS: Observational study including 552 patients presenting definite IE post-TAVR. Patients were divided in 2 groups according to the timing of TAVR (historical cohort [HC]: before 2014; contemporary cohort [CC]: after 2014). RESULTS: Overall incidence rates of IE were similar in both cohorts (CC vs HC: 5.45 vs 6.52 per 1000 person-years; Pâ =â .12), but the rate of early IE was lower in the CC (2.29 vs 4.89, Pâ <â .001). Enterococci were the most frequent microorganism. Most patients presented complicated IE ( CC: 67.7%; HC: 69.6%; Pâ =â .66), but the rate of surgical treatment remained low (CC: 20.7%; HC: 17.3%; Pâ =â .32). The CC exhibited lower rates of in-hospital acute kidney injury (35.1% vs 44.6%; Pâ =â .036) and in-hospital (26.6% vs 36.4%; Pâ =â .016) and 1-year (37.8% vs 53.5%; Pâ <â .001) mortality. Higher logistic EuroScore, Staphylococcus aureus etiology, and complications (stroke, heart failure, and acute renal failure) were associated with in-hospital mortality in multivariable analyses (Pâ <â .05 for all). CONCLUSIONS: Although overall IE incidence has remained stable, the incidence of early IE has declined in recent years. The microorganism, high rate of complications, and very low rate of surgical treatment remained similar. In-hospital and 1-year mortality rates were high but progressively decreased over time.

OBJECTIVES: To determine the occurrence of vascular complications (VCs) following transfemoral transcatheter aortic valve replacement (TAVR) with new-generation devices according to the use of a crossover technique (COT). BACKGROUND: The use of a COT (with/without balloon) has been associated with a reduction of VCs in TAVR patients. However, scarce data support its use with second-generation devices. Also, its potential benefit in obese patients (at high-risk of VCs) has not been elucidated. METHODS: A multicenter study including 2214 patients who underwent full percutaneous transfemoral TAVR (COT, 1522 patients; no COT, 692 patients). Thirty-day events were evaluated according to the use of a COT using a multivariate logistic regression model. A subanalysis was performed in obese patients. RESULTS: Primary access major VCs (3.5% COT vs 3.9% no COT; P=.19), major/life-threatening bleeding (3.4% COT vs 2.0% no COT; P=.33), and mortality rates (2.4% COT vs 2.6% no COT; P=.23) were similar between groups. However, minor VCs (11.7% COT vs 5.9% no COT; P<.001) and postprocedural acute renal failure (8.9% COT vs 3.9% no COT; P<.001) were higher in patients undergoing the COT. In the overall cohort, percutaneous closure device failure was more frequent in obese patients (4.0% in the obese group vs 1.9% in the non-obese group; P<.01), but these differences were no longer significant in those undergoing a COT (3.4% in the obese group vs 2.0% in the non-obese group; P=.12). Indeed, in the subset of obese patients, the COT tended to be associated with fewer VCs (3.4% COT vs 5.9% no COT; P=.09). CONCLUSIONS: The use of a COT was not associated with a reduction of major VCs or improved outcomes. However, some patient subsets, such as those with higher body mass index, may benefit from the use of a COT. These findings would suggest the application of a tailored strategy, following a risk-benefit assessment in each TAVR candidate.

AIMS: We determined the incidence and type of arrhythmias at 2-year follow-up in patients with new-onset persistent left bundle branch block (LBBB) following transcatheter aortic valve replacement (TAVR). METHODS AND RESULTS: Multicentre prospective study including 103 consecutive patients with new-onset persistent LBBB post-TAVR (SAPIEN XT/3: 53; CoreValve/Evolut R: 50). An implantable cardiac monitor (Reveal XT, Reveal Linq) was implanted before hospital discharge and patients had continuous monitoring for up to 2 years. Arrhythmic events were adjudicated in a central core lab. 1836 new arrhythmic events (tachyarrhythmias: 1655 and bradyarrhythmias: 181) occurred at 2 years. Of these, 283 (15%) occurred beyond 1 year (tachyarrhythmias 212, bradyarrhythmias 71) in 33 (36%) patients, without differences between valve type. Most late (>1 year) arrhythmic events were asymptomatic (94%) and led to a treatment change in 17 (19%) patients. A total of 71 late bradyarrhythmias [high-degree atrioventricular block (HAVB): 3, severe bradycardia: 68] were detected in 17 (21%) patients. At 2 years, 18 (17%) patients had received a permanent pacemaker (PPM) or implantable cardiac-defibrillator. PPM implantation due to HAVB predominated in the early phase post-TAVR, with only 1 HAVB event requiring PPM implantation after 1 year. CONCLUSION: Patients with new-onset LBBB post-TAVR exhibited a very high burden of arrhythmic events within the 2 years post-procedure. While new tachyarrhythmic events were homogeneously distributed over time, the vast majority of new HAVB episodes leading to PPM implantation occurred early after the procedure. These results should help to guide the management of this challenging group of patients. (clinicaltrials.gov: NCT02153307).

AIMS: Permanent pacemaker implantation (PPI) may be required after transcatheter aortic valve implantation (TAVI). Evidence on PPI prediction has largely been gathered from high-risk patients receiving first-generation valve implants. We undertook a meta-analysis of the existing literature to examine the incidence and predictors of PPI after TAVI according to generation of valve, valve type, and surgical risk. METHODS AND RESULTS: We made a systematic literature search for studies with ≥100 patients reporting the incidence and adjusted predictors of PPI after TAVI. Subgroup analyses examined these features according to generation of valve, specific valve type, and surgical risk. We obtained data from 43 studies, encompassing 29 113 patients. Permanent pacemaker implantation rates ranged from 6.7% to 39.2% in individual studies with a pooled incidence of 19% (95% CI 16-21). Independent predictors for PPI were age [odds ratio (OR) 1.05, 95% confidence interval (CI) 1.01-1.09], left bundle branch block (LBBB) (OR 1.45, 95% CI 1.12-1.77), right bundle branch block (RBBB) (OR 4.15, 95% CI 3.23-4.88), implantation depth (OR 1.18, 95% CI 1.11-1.26), and self-expanding valve prosthesis (OR 2.99, 95% CI 1.39-4.59). Among subgroups analysed according to valve type, valve generation and surgical risk, independent predictors were RBBB, self-expanding valve type, first-degree atrioventricular block, and implantation depth. CONCLUSIONS: The principle independent predictors for PPI following TAVI are age, RBBB, LBBB, self-expanding valve type, and valve implantation depth. These characteristics should be taken into account in pre-procedural assessment to reduce PPI rates. PROSPERO ID CRD42020164043.
