5-year Outcomes Following Valve-in-Ring and Valve-in-Valve Procedures for Failing Mitral Annuloplasty Rings and Bioprosthetic Valves.

This article discusses the long-term outcomes of valve-in-ring (ViR) and valve-in-valve (ViV) procedures for failing mitral annuloplasty rings and bioprosthetic valves. The study analyzed data from 51 patients who underwent these procedures between 2014 and 2023. The results showed that the procedures had a reasonable safety and durability profile up to 5 years, with an overall survival rate of 87.5% and 83.4% after ViR and ViV, respectively. However, there were cases of significant paravalvular leakage in patients with rigid annuloplasty rings, which required additional leakage closure. The study also noted a shift from the transapical to the transseptal approach over the last decade, reducing procedural trauma. [Extracted from the article]
