Abstract

Background: Resection has been the main treatment for posterior leaflet prolapse for many years. However, there has been a change to other methods that promote leaflet tissue preservation. This study aimed to evaluate mitral valve repair with mid term follow up by new technique in isolated posterior mitral valve (MV) prolapse other than traditional techniques. Methods: Here in, we conducted a clinical trial of a retrospective study of 58 patients who had undergone MV repair with our triangular exclusion of P2 strategy between June 2020 to June 2023. The mean age of cases with posterior MV prolapse is 42.6 ± 12.5 years. All patients were evaluated after six months and one year to assess the outcome of the repair technique. Results: a statistically significant variation was observed in the mitral regurgitation grade between the preoperative, intra-operative, and 6–12 months postoperative follow up periods. Conclusions: Triangular Exclusion of the P2 Strategy is an effective strategy and can be considered as an alternative to the classical mitral valve repair techniques with excellent mid-term follow up.
