Key result
Paravalvular leak after TAVI is a frequent complication driven by anatomical factors such as aortic annulus shape and calcification, as well as procedural factors including valve type and sizing.
Why the study?
What are the anatomical and procedural predictors of paravalvular leak after TAVI in patients with severe aortic stenosis?
What are the anatomical and procedural predictors of paravalvular leak after TAVI in patients with severe aortic stenosis?
This paper reviews the anatomical and procedural predictors of paravalvular leak, a frequent complication of TAVI that significantly affects patient prognosis.
Awareness of these predictors may guide TAVI planning to reduce paravalvular leak; extends observational synthesis but leaves open prospective validation.
Many studies have shown that transcatheter aortic valve implantation (TAVI) improves outcomes in patients with severe aortic stenosis in whom a classical surgical procedure cannot be performed due to the high risk. As one of the most frequent periprocedural complications of TAVI, paravalvular leak significantly affects the short- and long-term prognosis for patients undergoing implantation. In this paper, we analyze the most significant anatomical and procedural predictors of paravalvular leak after TAVI.

Wilczek et al. (2015) conducted a review in Severe aortic stenosis. Transcatheter aortic valve implantation (TAVI) was evaluated. Paravalvular leak after TAVI is a frequent complication driven by anatomical factors such as aortic annulus shape and calcification, as well as procedural factors including valve type and sizing.
