Introduction Paravalvular leak (PVL) is a severe complication of transcatheter aortic valve replacement (TAVR) that can lead to poor outcomes. TAVR-in-TAVR is a promising treatment for PVL; however, reports on its safety or efficacy are limited. In this study, we aimed to investigate the clinical outcomes of TAVR-in-TAVR using balloon-expandable prostheses for PVLs after TAVR. Methods We retrospectively analyzed data from patients who underwent TAVR-in-TAVR using balloon-expandable Sapien prostheses for PVL after an initial TAVR at our institution. The procedural success, in-hospital complications, all-cause mortality, and echocardiographic data for up to 2 years post-surgery were evaluated. Results In total, 31 patients with a mean age of 81.1 ± 7.9 years and mean Society of Thoracic Surgeons score of 8.8 ± 5.4% were identified. The procedural success rate of TAVR-in-TAVR was 96.8% (30/31). No in-hospital deaths, cardiac tamponade, or conversion to sternotomy occurred. Re-intervention was performed in only one patient (3.2%) during hospitalization. The all-cause mortality rates at 30 days and 2 years were 0% and 16.1%, respectively. A significant reduction in the PVL rate was observed at 30 days compared with that at baseline (p < 0.01). Discussion Our findings suggest that TAVR-in-TAVR using balloon-expandable prostheses is safe and effective for PVL after TAVR with low complication rates and acceptable long-term outcomes. Further studies with larger sample sizes are needed to confirm our findings. |
