Initial Single-center Experience with Premeasured Chordal Loops for Mitral Valve Repair

pp. 219-222

Abstract

Background: Mitral valve repair has demonstrated better outcomes compared with valve replacement for the treatment of degenerative mitral regurgitation.

Objective: The aim of this study was to show the experience with premeasured expanded polytetrafluoroethylene chordal loops for successful mitral valve repair.

Methods: Between May and December 2018, 13 patients with severe mitral regurgitation caused by degenerative disease and indication for surgery underwent mitral valve repair at Hospital Universitario Austral.

Results: The procedure was successful in the 13 patients. Chordal loops were applied to the anterior leaflet in 4 patients, to the posterior leaflet in 6 patients and to both anterior and posterior leaflets in 3 patients.

Conclusions: Polytetrafluoroethylene chordal loops allowed the satisfactory, safe and reproducible repair of mitral regurgitation due to prolapse of any mitral leaflet segment.
