Project description:ImportancePrior studies investigating the long-term clinical outcomes of patients who have undergone permanent pacemaker implantation after aortic valve replacement reported conflicting results.ObjectiveTo investigate long-term outcomes after primary surgical aortic valve replacement among patients who underwent postoperative permanent pacemaker implantation.Design, setting, and participantsThis cohort study included all patients who underwent surgical aortic valve replacement in Sweden from 1997 to 2018. All patients who underwent primary surgical aortic valve replacement in Sweden and survived the first 30 days after surgical treatment were included. Patients who underwent preoperative permanent pacemaker implantation, concomitant surgical treatment for another valve, or emergency surgical treatment were excluded. Patients who underwent concomitant coronary artery bypass grafting or surgical treatment of the ascending aorta were included. Follow-up data were complete for all patients. Data were analyzed from October through December 2020.ExposuresPatients underwent implantation of a permanent pacemaker or implantable cardioverter defibrillator within 30 days after aortic valve replacement.Main outcomes and measuresThe primary outcome was all-cause mortality.ResultsAmong 24 983 patients who underwent surgical aortic valve replacement, 849 patients (3.4%) underwent permanent pacemaker implantation within 30 days after surgical treatment and 24 134 patients (96.6%) did not receive pacemakers in that time. The mean (SD) age of the total study population was 69.7 (10.8) years, and 9209 patients were women (36.9%). The mean (SD) and maximum follow-up periods were 7.3 (5.0) years and 22.0 years, respectively. At 10 years and 20 years after surgical treatment, the Kaplan-Meier estimated survival rates were 52.8% and 18.0% in the pacemaker group, respectively, and 57.5% and 19.6% in the nonpacemaker group, respectively. All-cause mortality was statistically significantly increased in the pacemaker group compared with the nonpacemaker group (hazard ratio [HR], 1.14; 95% CI, 1.01-1.29; P = .03), and so was risk of heart failure hospitalization (HR, 1.58; 95% CI, 1.31-1.89; P < .001). No statistically significant increase was found in the risk of endocarditis in the pacemaker group.Conclusions and relevanceThis study found that there were increased risks of all-cause mortality and heart failure hospitalization among patients who underwent permanent pacemaker implantation after surgical aortic valve replacement, suggesting that these risks are important considerations, especially in an era when transcatheter aortic valve replacement is used in younger patients at lower risk of adverse surgical outcomes. These findings further suggest that future research should investigate how to avoid permanent pacemaker dependency after surgical and transcatheter aortic valve replacement.

Project description:Background: Patients with rheumatoid arthritis (RA) have increased risk of developing cardiovascular disease and events. Little is, however, known about the influence of RA to the outcomes after surgical aortic valve replacement (SAVR). Methods: In a retrospective, nationwide, multicenter cohort study, RA patients (n = 109) were compared to patients without RA (n = 1090) treated with isolated SAVR for aortic valve stenosis. Propensity score-matching adjustment for baseline features was used to study the outcome differences in a median follow-up of 5.6 years. Results: Patients with RA had higher all-cause mortality (HR 1.76; CI 1.21-2.57; p = 0.003), higher incidence of major adverse cardiovascular events (HR 1.63; CI 1.06-2.49; p = 0.025), and they needed more often coronary artery revascularization for coronary artery disease (HR 3.96; CI 1.21-12.90; p = 0.027) in long-term follow-up after SAVR. As well, cardiovascular mortality rate was higher in patients with RA (35.7% vs. 23.4%, p = 0.023). There was no difference in 30-day mortality (2.8% vs. 1.8%, p = 0.518) or in the need for aortic valve reoperations (3.7% vs. 4.0%, p = 0.532). Conclusions: Patients with rheumatoid arthritis had impaired long-term results and increased cardiovascular mortality after SAVR for aortic valve stenosis. Special attention is needed to improve outcomes of aortic valve stenosis patients with RA after SAVR.

Project description:Surgical aortic valve replacement (AVR) remains the gold standard therapy for severe aortic stenosis. Long-term survival data following AVR is required. Our objective was to provide a detailed contemporary benchmark of long-term survival following AVR among elderly patients (≥65 years) in the UK.We conducted a retrospective cohort study of 1815 adult patients undergoing surgical AVR± coronary artery bypass graft (CABG) surgery at a single UK centre between 1996 and 2011. Our main outcome was patient survival, which was assessed by linkage to census records at the Office for National Statistics.The mean age of the cohort was 75 (±5.6) years. Patients in the AVR alone group had a slightly higher median survival of 10.9 (95% CI 10.5 to 11.8) years than the AVR+CABG group which had a median survival of 9.6 (95% CI 8.7 to 10.1) years (p=0.001 of log-rank test (LRT) for equality of survivor functions). The presence of chronic kidney disease, severely impaired left ventricular function or being a current smoker were each associated with a ≥50% increased risk of long-term mortality. Comparison of our study cohort patients and the reference (operation year, age and gender matched) UK population suggested no difference in survival probability up to 8 years (p=0.55). However, for longer periods of follow-up, the difference became increasingly significant (p<0.0001).Long-term survival following surgical AVR in patients over 65 years of age is excellent and up to 8 years is comparable to the matched general population.

Project description:Little is known about the natural history of non-significant mitral and tricuspid regurgitation (MR and TR) following surgical aortic valve replacement (SAVR) for aortic regurgitation (AR). We retrospectively analyzed 184 patients (median age 64 (IQR, 55-74) years, 76.6% males) who underwent SAVR for AR. Subjects with significant non-aortic valvulopathies, prior/concomitant valvular interventions, or congenital heart disease were excluded. The cohort was evaluated for MR/TR progression and, based on the latter's occurrence, for echocardiographic and clinical indices of heart failure and mortality. By 5.8 (IQR, 2.8-11.0) years post-intervention, moderate or severe MR occurred in 20 (10.9%) patients, moderate or severe TR in 25 (13.5%), and either of the two in 36 (19.6%). Patients who developed moderate or severe MR/TR displayed greater biventricular disfunction and functional limitation and were less likely to be alive at 7.0 (IQR, 3.4-12.1) years compared to those who did not (47.2 vs. 79.7%, p < 0.001). The emergence of significant MR/TR was associated with preoperative atrial fibrillation/flutter, symptomatic heart failure, and above-mild MR/TR as well as concomitant composite graft use, but not with baseline echocardiographic measures of biventricular function and dimensions, aortic valve morphology, or procedural aspects. In conclusion, among patients undergoing SAVR for AR, significant MR/TR developed in one fifth by six years, correlated with more adverse course, and was anticipated by baseline clinical and echocardiographic variables.

Project description:Permanent pacemaker implantation is associated with an increased risk of mortality and heart failure after surgical aortic valve replacement (SAVR). The purpose of this study was to analyze long-term prognosis of permanent pacemaker implantation following SAVR on low-risk patients. This nationwide, population-based, observational cohort study included all patients who underwent SAVR in Sweden between 2001 and 2018 with low surgical risk, defined as logistic EuroSCORE I <10% or EuroSCORE II <4%. Patients received a permanent pacemaker implantation within 30 days after SAVR. Main outcomes were all-cause mortality, heart failure hospitalization, and endocarditis. Regression standardization addressed confounding. We included 19,576 patients with low surgical risk. Of these, 732 (3.7%) patients received a permanent pacemaker within 30 days after SAVR. The mean age was 68 years and 33% were women. We found no difference in all-cause mortality between patients who received a pacemaker compared to those who did not (absolute survival difference at 17 years: 0.1% (95% CI: -3.6% to 3.8%). After 17 years, the estimated cumulative incidence of heart failure in patients who received a pacemaker was 28% (95% CI: 24%-33%) vs 20% (95% CI: 19%-22%) in patients who did not (absolute difference 8.2% [95% CI: 3.8%-13%]). We found no difference in endocarditis between the groups. We found an increased incidence of heart failure in patients with low surgical risk who received a permanent pacemaker after SAVR. Permanent pacemaker implantation was not associated with all-cause mortality or endocarditis. Efforts should be made to avoid the need for permanent pacemaker following SAVR.

Project description:ObjectivesWe investigated whether the selective use of supracoronary ascending aorta replacement achieves late outcomes comparable to those of aortic root replacement for acute Stanford type A aortic dissection (TAAD).MethodsPatients who underwent surgery for acute type A aortic dissection from 2005 to 2018 at the Helsinki University Hospital, Finland, were included in this analysis. Late mortality was evaluated with the Kaplan-Meier method and proximal aortic reoperation, i.e. operation on the aortic root or aortic valve, with the competing risk method.ResultsOut of 309 patients, 216 underwent supracoronary ascending aortic replacement and 93 had aortic root replacement. At 10 years, mortality was 33.8% after aortic root replacement and 35.2% after ascending aortic replacement (P = 0.806, adjusted hazard ratio 1.25, 95% confidence interval, 0.77-2.02), and the cumulative incidence of proximal aortic reoperation was 6.0% in the aortic root replacement group and 6.2% in the ascending aortic replacement group (P = 0.65; adjusted subdistributional hazard ratio 0.53, 95% confidence interval 0.15-1.89). Among 71 propensity score matched pairs, 10-year survival was 34.4% after aortic root replacement and 36.2% after ascending aortic replacement surgery (P = 0.70). Cumulative incidence of proximal aortic reoperation was 7.0% after aortic root replacement and 13.0% after ascending aortic replacement surgery (P = 0.22). Among 102 patients with complete imaging data [mean follow-up, 4.7 (3.2) years], the estimated growth rate of the aortic root diameter was 0.22 mm/year, that of its area 7.19 mm2/year and that of its perimeter 0.43 mm/year.ConclusionsWhen stringent selection criteria were used to determine the extent of proximal aortic reconstruction, aortic root replacement and ascending aortic replacement for type A aortic dissection achieved comparable clinical outcomes.

Project description:To analyse the impact of postprocedural mitral regurgitation (MR), in an interaction with aortic regurgitation (AR), on mortality following transcatheter aortic valve implantation (TAVI).To assess the interaction between MR and AR, we compared the survival rate of patients (i) without both significant MR and AR versus (ii) those with either significant MR or significant AR versus (iii) with significant MR and AR, all postprocedure. 381 participants of the Polish Transcatheter Aortic Valve Implantation Registry (166 males (43.6%) and 215 females (56.4%), age 78.8±7.4 years) were analysed. Follow-up was 94.1±96.5 days.In-hospital and midterm mortality were 6.6% and 10.2%, respectively. Significant MR and AR were present in 16% and 8.1% patients, including 3.1% patients with both significant MR and AR. Patients with significant versus insignificant AR differed with respect to mortality (log rank p=0.009). This difference was not apparent in a subgroup of patients without significant MR (log rank p=0.80). In a subgroup of patients without significant AR, there were no significant differences in mortality between individuals with versus without significant MR (log rank p=0.44). Significant MR and AR had a significant impact on mortality only when associated with each other (log rank p<0.0001). At multivariate Cox regression modelling concomitant significant MR and AR were independently associated with mortality (OR 3.2, 95% CI 1.54 to 5.71, p=0.002).Significant MR or AR postprocedure, when isolated, had no impact on survival. Combined MR and AR had a significant impact on a patient's prognosis.

Project description:Background: Traditionally, the only effective treatment for aortic stenosis was surgical aortic valve replacement (SAVR). Transcatheter aortic valve replacement (TAVR) was approved in the United States in late 2011 and provided a critical alternative therapy. Our aims were to investigate the trends in the utilization of SAVR in the early vs. late TAVR era and to assess SAVR and TAVR outcomes. Methods: Using the 2011-2017 National Inpatient Sample database, we identified hospitalizations for patients with a most responsible diagnosis of aortic stenosis during which an aortic valve replacement (AVR) was performed, either SAVR or TAVR. Patients' sociodemographic and clinical characteristics, procedure complications, length of stay, and mortality were analyzed. Multivariable analyses were performed to identify predictors of in-hospital mortality. Piecewise regression analyses were performed to assess temporal trends in SAVR and TAVR utilization. Results: A total of 542,734 AVR procedures were analyzed. The utilization of SAVR was steady until 2014 with a significant downward trend in the following years 2015-2017 (P = 0.026). In contrast, a steady upward trend was observed in the TAVR procedure with a significant increase during the years 2015-2017 (P = 0.006). Higher in-hospital mortality was observed in SAVR patients. The mortality rate declined from 2011 to 2017 in a significantly higher proportion in the TAVR compared with the SAVR group. Conclusion: Utilization of SAVR showed a downward trend during the late TAVR era (2015-2017), and TAVR utilization demonstrated a steady upward trend during the years 2011-2017. Higher in-hospital mortality was recorded in patients who underwent SAVR.

Project description:BackgroundTranscatheter aortic valve replacement (TAVR) has become the standard of care in the majority of patients with symptomatic severe aortic stenosis. Data on long-term mortality and durability of transcatheter heart valves (THVs) beyond 5 years are limited. Our study aimed to assess elderly and high-risk patients' long-term outcomes treated with TAVR in a prospective single-centre registry focusing on the durability of THVs.MethodsWe included 795 patients with severe calcific aortic stenosis treated by transfemoral TAVR between 2006 and 2011. Echocardiography was performed at baseline; discharge; 1 year; and afterward, annually, until the longest available follow-up. Mortality rates were estimated for 1, 5, 6, 7, and 8 years. The rates of structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) were assessed in accordance with consensus definitions. Outcome measures were adjudicated according to Valve Academic Research Consortium-2 (VARC-2).ResultsMedian (interquartile range) follow-up time was 1345 (316; 2015) days. One-year, 5-year, 6-year, 7-year, and 8-year overall mortality was 25.4%, 59.0%, 64.6%, 67.9%, and 69.2%, respectively. At 8 years, no significant differences in mortality were found comparing self-expanding vs balloon-expandable valves (69.5% vs 68.0%, P = 0.709) and postdilatation (PD) vs no-PD (69.4% vs 69.2%, P = 0.363). SVD was detected in 26 patients (3.3%), and 19 (2.4%) of the 795 patients had evidence of BVF during follow-up.ConclusionsOur study demonstrates good long-term results for high-risk patients who were alive up to 8 years after TAVR.
