Abstract :Objectives:Both resectional and non-resectional strategies used in the management of isolated posterior mitral leaflet repair have their own pros and cons, with no current consensus on their comparative superiority. In this study, operative and postoperative outcomes in patients undergoing isolated posterior leaflet repair with or without resection have been compared. Methods: A total of 129 patients undergoing isolated posterior leaflet repair due to mitral failure were included. Among these, several resection techniques including triangular, quadrangular, or sliding-leaflet annuloplasty were used in 63, while non-resection techniques such as plication, chorda shortening, chorda transfer, or artificial chorda implantation were implemented in 66. Results:Resection group had longer cross-clamp and cardiopulmonary bypass time as compared to the non-resection group. The two groups were similar in terms of intra-operative IABP or inotropic support as well as early and late mortality and re-operation rates. At 12 months postoperatively, there were no significant differences in echocardiographic parameters. Conclusion:Resectional and chordal replacement techniques are associated with comparable success rates. While resectional methods offer the advantage of providing curative treatment through removal of pathological tissue, chordal replacement techniques are associated with a predictable success rate in the context of a practical method that can be accomplished rapidly.
