    Abstract:
    Chordal transfer and chordal replacement techniques have been quite successful for repair of anterior mitral leaflet prolapse in degenerative disease, but largely unexplored in rheumatic patients. To extend the scope of valve repair, we assessed the chordal transfer technique for correction of anterior mitral leaflet prolapse in 57 patients with rheumatic mitral regurgitation, who were treated between October 2008 and March 2010. There were 36 women and 21 men with a mean age of 25 ± 7.4 years. Normal chordae and a strip of leaflet tissue were transferred from the posterior leaflet to the free edge of the anterior leaflet; the posterior leaflet was repaired in the same manner as after quadrangular resection. Additional procedures were commissurotomy in 19 patients, aortic valve replacement in 1, tricuspid repair in 5, and cryo maze operations in 21. There was no hospital mortality. One (1.7%) patient had acute renal failure but recovered fully. There was moderate regurgitation in one patient who had undergone simultaneous aortic valve replacement. At a mean follow-up of 6.2 ± 2 months, 56/57 (98.2%) patients were asymptomatic with no significant mitral regurgitation.
