Need for permanent pacemaker implantation following implantation of the rapid deployment valve in combined procedures: a single centre cohort study.

ABSTRACT:

Background

Rapid deployment aortic valves may interfere with the cardiac conduction system. We investigated the need for permanent pacemaker implantation (PPI) following the implantation of Edwards INTUITY valve (Edwards Lifesciences, Irvine, CA).

Methods

One hundred twenty patients underwent aortic valve replacement (AVR) with the INTUITY valve in a combined procedure at the German Heart Centre Munich between April 2016 and December 2019. Twenty-four patients with prior PPI or concomitant ablation procedures (24/120, 20%) were excluded. Patient-specific, procedural and post-procedural outcomes were assessed in the remaining 96 cases.

Results

AVR was successful in all cases. Seventy-four percent of the study population were men. Mean age was 69.5±7.6 years. EuroSCORE II was 3.2±2.9. Forty-six patients (46/96, 47.9%) presented with pre-operative conduction disorders, right bundle branch block (RBBB) (17/96, 17.7%) and first-degree or second degree atrio-ventricular block (AVB) (18/96, 18.8%), in particular. In total, 9 patients (9/96, 9.4%) underwent PPI. PPI was required in 3 patients (3/50, 6.0%) who did not have a pre-existing conduction disorder due to new high degree AVB. 6 patients with pre-operative conduction disorders (6/46, 13%) needed PPI. Timing of PPI was 5.2±1.5 days (median 5). Independent predictors of PPI were preoperative RBBB [odds ratio (OR) =4.554, P=0.049] and large valve size (#27) (OR =5.527, P=0.031).

Conclusions

The analysis of the data collected enabled us to identify patient factors associated with higher risk for post-operative PPI following AVR with the INTUITY valve. Patient factors associated with post-operative PPI, were RBBB and large valve size. These patients should be closely monitored following the procedure, in particular.

Project description:ObjectivePermanent pacemaker implantation (PPI) risk is higher following transcatheter aortic valve implantation (TAVI) than surgical valve replacement. Native aortic leaflets are retained in patients undergoing TAVI, unlike in surgical valve replacement. Whether the retained leaflets influence PPI risk because of their proximity to the conduction system is unknown. The study sought to determine the association between infra-annular extension of native right coronary cusp/noncoronary cusp (RCC/NCC) post balloon-expandable TAVI and PPI risk.MethodsWe performed a retrospective analysis of 190 patients undergoing balloon-expandable TAVI at a single center. Manifestation of infra-annular extension of RCC/NCC was considered to be present when part of leaflet extended below aortic-annular plane on post-implantation aortic-root angiography.ResultsInfra-annular extension of RCC/NCC was observed in 33 patients (17.37%). PPI incidence post-TAVI was higher in patients with infra-annular extension of RCC/NCC than in those without (36.36% versus 8.92%, relative-risk: 4.08, p˂0.0001). On logistic-regression analysis, preexisting right bundle-branch block (RBBB) (odds-ratio: 12.73, 95% confidence-interval: 2.16-74.93, p = 0.005), and infra-annular extension of RCC/NCC (odds-ratio: 5.63, 95% confidence-interval: 2.17-14.58, p < 0.0001) were independently associated with PPI risk. Preexisting RBBB (φ = +0.25, p = 0.001) and infra-annular extension of RCC/NCC (φ = +0.30, p < 0.0001) showed a positive-correlation with PPI risk. Infra-annular extension of RCC/NCC was a significant predictor of PPI risk on receiver-operating-characteristic curve analysis (area under-the-curve 0.67; 95% confidence-interval: 0.54-0.79, p = 0.006).ConclusionThe retained native aortic leaflets play a significant role in PPI risk following balloon-expandable TAVI. Infra-annular extension of RCC/NCC is a novel predictor, and is associated with a four-fold higher risk of PPI.

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.
