[Ischemic cardiomyopathy treated with overlapping ventriculoplasty]

Abstract

A 58-year-old man was admitted due to congestive heart failure. Left ventriculography showed end-diastolic volume index (EDVI) of 172 ml/m2 and ejection fraction (EF) of 16%. Coronary angiography showed severe double vessel disease (the left anterior descending artery and the right coronary artery). Echocardiography showed dilated heart [left ventricular end-diastolic diameter (LVDd) of 74 mm] and severe mitral regurgitation due to tethering of the leaflets. The patient underwent our original left ventricular volume reduction operation, termed overlapping ventriculoplasty (OLVP) combined with mitral annuloplasty, papillary muscles plication (PMP) and coronary artery bypass grafting (CABG). The postoperative course was excellent. Postoperatively, the EDVI decreased to 96 ml/m2, the LVDd diminished to 67 mm, and the EF improved to 34%. This case implies the role of left ventricular remodeling procedure of OLVP and PMP in the ischemic cardiomyopathy with ischemic mitral regurgitation.
