Quality Of Life Outcomes In Transcatheter Aortic Valve Replacement Patients Requiring Pacemaker Implantation
JOURNAL OF ARRHYTHMIA(2017)
摘要
BackgroundPermanent pacemaker implantation is the most common complication after Transcatheter aortic valve replacement (TAVR) and is associated with worse outcomes and mortality. However, its impact on quality-of-life (QoL) outcomes remains unknown. MethodsWe included 383 consecutive patients undergoing TAVR from January 2012 to 2016 who completed a baseline Kansas City Cardiomyopathy Questionnaire (KCCQ-12) health survey. The clinical, laboratory, angiographic, QoL, mortality, and occurrence of poor outcomes (KCCQ-12 score < 45 or KCCQ decrease of 10 points) were obtained. ResultsThe mean age was 83 8 years, 51% were men, and majority were Caucasians (n = 364, 95%). Permanent pacemaker (PPM) was implanted in 11.5% of patients post-TAVR. PPM patients were more likely to have prior conduction disease including RBBB (25% vs 12%, P = .02) and PQ interval >250 ms (11% vs 5%, P = .07). One-month median KCCQ-12 scores were significantly lower among PPM patients (84.7 vs 68.8, P = .04), but did not differ significantly at 1-year (86.5 vs 90.6, P = .5) post-TAVR. Occurrence of poor outcomes did not differ significantly among those with or without PPM at 1 month (11% vs 7%, P = .39) and 1 year (13% vs 9%, P = .45), respectively. However, patients with poor QoL outcomes at 1 month post-TAVR also had significantly worse mortality during follow-up in unadjusted (31.3% vs 4.5%, P < .001) and adjusted (HR = 5.30, 95% [CI: 1.85-15.22, P = .002])analyses, respectively. ConclusionPermanent pacemaker implantation is associated with short-term reduction in QoL without long-term implications post-TAVR. Patients with poor QoL post-TAVR also have significantly higher mortality.
