Aortic regurgitation after transcatheter aortic valve implantation: mechanisms and implications.
Key result
Post-TAVI AR affects ~70% of patients with even mild cases linked to decreased survival.
Why the study?
Aortic regurgitation remains a major concern after TAVI, and accurate evaluation and classification of AR are important due to its association with decreased survival.

This review highlights the mechanisms of aortic regurgitation after TAVI, emphasizing the importance of accurate evaluation and classification to improve device design and clinical outcomes.
Cite This Study
Stähli et al. (2013) conducted a review in Severe aortic stenosis. Transcatheter aortic valve implantation (TAVI) was evaluated. Aortic regurgitation after TAVI occurs in up to 70% of patients and can be classified into transvalvular, paravalvular, and supra-skirtal types, with even mild AR decreasing survival.
