Background and aim of the study: Most valve repair techniques require resection and multiple sutures. In the present study, a novel technique without resection for correction of posterior leaflet prolapse due to chordal elongation or rupture was employed, the aim being to evaluate the outcomes of a nonresecting valve repair technique in patients with posterior leaflet prolapse that caused significant mitral regurgitation (MR).

Methods: Between May 2008 and December 2010, a total of 90 consecutive patients with posterior leaflet prolapse (55 males, 35 females; mean age 51.5 ± 14.6 years) underwent patch valvuloplasty. The procedure involved suturing the free margin of the prolapsed leaflet, invagination of the folded leaflet tissue into the left ventricular side, coverage of the dimpled portion with a round bovine pericardial patch using a continuous suture technique, and reshaping of the posterior annulus using a 53- to 61-mm strip. All patients underwent postoperative

echocardiography after a mean follow up of 41.9 ± 10.4 months.

Results: No early death occurred, but there was one late death due to a non-cardiac cause. At the last echocardiographic follow up, 81 patients (90%) showed none or trace MR, seven (7.8%) had mild MR, and two (2.2%) moderate MR. The mean mitral valve area was 2.4 ± 0.5 cm2 and the mean pressure gradient 2.8 ± 1.2 mmHg. No patient required  reoperation due to recurrent or aggravated MR.

Conclusion: In patients with posterior leaflet prolapse, the applied patch valvuloplasty technique was useful and reliable, showing excellent clinical and echocardiographic outcomes. Additional long term evaluations with close follow up should be performed.
