Objective: Only a few reports have detailed the early- to mid-term outcomes of transcatheter aortic valve replacement (TAVR), especially in patients with small body size. This study aimed to evaluate the early- and mid-term outcomes of redo-TAVR in Japanese patients.
Methods: This was a retrospective, non-randomized, single-center study. In all 16 consecutive cases (15 patients) who underwent redo-TAVR (excluding redo-TAVR because of intraoperative bailout) were enrolled in this study.
Results: The mean age was 82.1 ± 7.1 years, and 31.3% were men (mean body surface area was 1.45 ± 0.18 m2 and median STS score was 12.5%). Fifteen of the failed transcatheter aortic valves (TAVs) were balloon-expandable (bTAV), and one was a self-expanding TAV (sTAV). For a period of postoperative 30 days, all-cause mortality, all stroke, and moderate or greater patient-prosthesis mismatch were observed in 0%, 6.3%, and 25.0%, respectively. During the follow-up period (mean duration, 1154 days), freedom from cardiovascular mortality rates at postoperative 1 year and 3 years were 81.3% and 81.3%, respectively; freedom from all stroke rates at postoperative 1 year and 3 years were 93.8% and 73.1%, respectively; and freedom from structural valve deterioration rates at postoperative 1 year and 3 years were 92.9% and 92.9%, respectively.
Conclusions: Whether using the same or different types of TAV, the mid-term outcomes of redo-TAVR for bTAV and sTAV in the Japanese patients were favorable.
