Abstract

The prognosis of aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) and the changes in AR grade over time remain unclear. This study evaluated the midterm survival associated with AR after TAVI and examined the evolution of AR over time and its effect on cardiac performance. Successful TAVI was performed in 314 patients (age 81 ± 7 years, 36% men). Serial transthoracic echocardiography and clinical assessment were available in 175 patients who survived >12 months. AR was assessed in terms of overall, paravalvular, and intravalvular severity. Significant post-TAVI AR (grade ≥2) was observed in 82 patients (26%), and these patients showed a trend toward reduced survival at 1- (93% vs 91%) and 2-year (89% vs 74%, log-rank p = 0.063) follow-up. Of the 175 patients who survived >12 months, grade ≥2 overall, paravalvular, and intravalvular AR were noted in 47 (27%), 32 (18%), and 8 patients (5%), respectively. Significant overall and paravalvular AR appeared to improve over time, particularly during the first 6 months (p
