Does a small triangular leaflet resection with folding plasty and artificial chordae implantation improve outcomes in patients with mitral insufficiency due to posterior leaflet prolapse?
A modified triangular resection technique for posterior mitral leaflet prolapse appears safe and effective at preserving left ventricular geometry and function at 12 months.
Supports short-term safety in prolapse repair; leaves open durability versus standard techniques in larger trials.
The conventional treatment of mitral insufficiency, due to posterior leaflet prolapse, is quadrangular resection. This technique sacrifices a great amount of valve tissue resulting in leaflet stiffness and altered annular geometry. To avoid such problems we performed a small triangular leaflet resection sparing the second-order chordae, a folding plasty, implantation of artificial chordae, and annuloplasty. Fourteen patients underwent this procedure. No hospital death and no repair failure were observed. Echocardiography at 12 months on 12 patients showed trivial incompetence in three and mild in one and an overall improvement of end-diastolic and end-systolic diameters. Our technique has the main objectives of sparing second-order chordae and subvalvular apparatus in order to preserve mobility of the posterior mitral leaflet, left ventricular geometry, and function. Preliminary results are encouraging.

Col et al. (2006) conducted an observational in Mitral insufficiency due to posterior leaflet prolapse (n=14). Triangular leaflet resection, folding plasty, artificial chordae implantation, and annuloplasty was evaluated on Hospital death and repair failure. Triangular leaflet resection and folding plasty for mitral insufficiency resulted in 0% hospital mortality and 0% repair failure among 14 treated patients.
