[Clinical efficacy and safety of transcatheter aortic valve replacement for patients with severe pure native aortic regurgitation].

ABSTRACT:

Objectives

To evaluate the early clinical efficacy and safety of trans-catheter aortic valve replacement (TAVR) for patients with severe pure native aortic regurgitation (PNAR) who are not suitable for conventional surgical aortic valve replace-ment.

Methods

A retrospective analysis was conducted on 48 patients with PNAR who underwent TAVR at the Department of Cardiac Surgery, the First Affiliated Hospital of Sun Yat-sen University between March 2019 and February 2025. These included 25 cases with transfemoral approach (TF-TAVR group) and 23 cases with transapical approach (TA-TAVR group). Efficacy and safety were assessed by analyzing baseline characteristics, all-cause mortality, and procedure-related complications.

Results

Compared with the TA-TAVR group, the TF-TA
