AIMS: Comorbidities pose a major challenge to screening, selection and follow-up of transcatheter aortic valve implantation (TAVI) patients as well as to the procedure itself. The aim of the present study was to assess cardiac and non-cardiac readmission rates besides clinical endpoint data in the first 50 patients of a single center TAVI programme. METHODS AND RESULTS: TAVI was performed using the transfemoral CoreValve system. Procedural success rate was 94%; intraprocedural mortality was 2%. 82% of the patients remained free of a combined safety endpoint at 30 days, and 76.1% remained free of a combined efficacy endpoint at six months (modified criteria of the Valve Academic Research Consortium). At six months, among all surviving patients, 10.3% had experienced readmissions for cardiac causes, and 43.6% had experienced readmissions for non-cardiac causes. Causes of non-cardiac readmissions showed a wide distribution over various medical disciplines, reflecting the high rate of comorbidities. Beyond six months until a predefined reference date (mean follow up 9.9 months), the probability of hospitalization fell by half (1.54 vs. 0.74 hospital days per patient per month), driven by a decrease of non-cardiac readmissions. Karnofsky score before and after TAVI yielded a significant and sustained improvement of performance status, as assessed retrospectively at reference date. CONCLUSION: The findings of the present study suggest that the high prevalence of comorbidities in high-risk TAVI patients results in a high rate of non-cardiac rehospitalizations during the first 6 months of follow-up. Despite this fact, improvement of global everyday performance following TAVI as perceived by the patients seems to be substantial.
