title: Mitral valve repair for ischemic mitral regurgitation in dilated cardiomyopathy.
abstract: Ischemic mitral regurgitation contributes to poor survival in patients with heart failure. The intermediate-term outcome of mitral reconstruction in 15 patients who had ischemic dilated cardiomyopathy with mitral regurgitation requiring surgical intervention was studied. They underwent mitral valve repair along with coronary artery bypass surgery. The mitral valve coaptation depth was considered an important parameter in deciding on repair. Ages ranged from 43 to 72 years. Left ventricular ejection fractions were 15-38% (mean, 26.5% +/- 4.3%). The operative technique in all 15 patients was posterior annuloplasty using Dacron felt. At a mean follow-up of 4.6 +/- 1.2 months (1-8 months), postoperative transesophageal echocardiography revealed mild mitral regurgitation in 2 patients and none in 13. There was a significant improvement in New York Heart Association functional class from 3.9 +/- 1.1 to 1.9 +/- 0.3. Mitral valve repair by posterior felt annuloplasty provides favorable results in the intermediate-term in selected patients with ischemic cardiomyopathy and severe left ventricular dysfunction.
