This a retrospective study of 175 patients who had survived more than 12 months following TAVI and for whom there were clinical and echocardiographic follow up data. Outcomes were compared between patients with significant (grade II or more) aortic regurgitation (AR) and those without significant aortic regurgitation (less than grade II). Paravalvular, but not intravalvular, AR appeared to improve over time, mainly in the first 6 months. Patients who remained with significant AR grade at 6 month follow-up showed significantly worse survival than patients with less than grade II AR.
