Posterior leaflet reconstruction in mitral valve repair: Does resect versus respect strategy matter?

ABSTRACT:

Objective

Previous randomized controlled trials demonstrated comparable outcomes between posterior leaflet resections and neochord implantation in mitral valve (MV) repair. However, these studies were limited up to 1-year follow-up, and more recent evidence suggested that leaflet resections may offer superior long-term outcomes.

Methods

All patients who underwent MV repair with either resection or neochord implantation for posterior leaflet pathology between October 2011 and July 2024 were included. Propensity-score matching was used.

Results

A total of 457 patients underwent posterior leaflet reconstruction, with 334 (73.1%) requiring leaflet resection (resection group) and 123 (26.9%) receiving neochordae (neochord group). The median [interquartile range] follow-up
