ABSTRACT
Background/Objectives:
Despite procedural improvements, post-transcatheter aortic valve replacement (TAVR) conduction disorders remain high. Analyzing the data from a monocentric TAVR registry, this study aims to determine predictive factors for PPI (primary outcome), the indication for PPI, and long-term outcomes among these patients (secondary outcomes).Methods:
Conducted at Clairval Hospital in Marseille, France, this retrospective study included all consecutive patients from June 2012 to June 2019. Clinical, electrocardiographic, echocardiographic, and procedural data were collected, with outcomes assessed annually. Logistic regression identified PPI predictors and survival analyses were performed.Results:
Of the 1458 patients initially considered, 1157 patients were included. PPI was needed in 21.5% of patients, primarily for third-degree atrioventricular block (46.4%). Predictor factors for PPI included baseline right bundle branch block (ORadj 2.49, 95% CI 1.44 to 4.30; p = 0.001), longer baseline QRS duration (ORadj 1.01, 95% CI 1.00 to1.02, p = 0.002), and self-expandable valves (ORadj 1.82, 95% CI, 1.09 to 3.03; p = 0.021). Seven-year estimated mortality was higher in PPI (43.3%) vs. non-PPI patients (30.9%) (log rank p = 0.048). PPI was an independent predictive factor of death (ORadj 2.49, 95% CI 1.4 to 4.3; p = 0.002).Conclusions:
This study reveals elevated rates of PPI post-TAVR associated with increased mortality. These results underscore the pressing necessity to refine our practices, delineate precise indications, and enhance the long-term prognosis for implanted patients.
