Predictors of moderate‐to‐severe paravalvular aortic regurgitation immediately after corevalve implantation and the impact of postdilatation

Abstract

The appropriate strategy for treating patients with AR≥2+ depends on the causes and severity of AR post-TAVI. This study suggests that we should carefully select the size of CoreValve prosthesis to prevent prosthesis mismatch, especially when implanted in larger annulus sizes. For valves implanted in the appropriate position, postdilatation appears effective in reducing the degree of AR.
