Objective To investigate the treatment and prognosis of moderate ischemic mitral regurgitation (IMR) in coronary artery disease(CAD). Methods From January 1998 to May 2006, 28 patients of CAD with moderate IMR underwent coronary artery bypass grafting (CABG) and mitral valve plasty(MVP, 24) or mitral valve replacement (MVR,4). The Reed method were used in 9 cases, the annuloplasty ring were used in 15 cases. Mechanical valve were implanted in 1 case and biological valve in 3 cases. Results There was no operative or hospital death. Twentysix patients were followed up to a mean period of 41 months. There were two late death(one was MVP, the other was MVR). In MVP cases, nineteen patients were in New York Heart Association (NYHA) functional class Ⅰ and Ⅱ, 3 in class Ⅲ, which was better than that of preoperative one. Ultrasonic cardiography (UCG) examination showed no mitral regurgitation in 5 cases, mild in 7, light in 6, moderate in 3, severe in 1. Left atrial volume (LAV) and left ventricular enddiastolic volume (LVEDV) were 54.1±12.7ml and 60.9±14.8 ml, decreased more significantly than that preoperatively (P lt;0.05). In MVR cases, 2 cases were survival and followed. One patient was in NYHA functional class Ⅰ, 1 in class Ⅱ, which was better than that of preoperative one. Conclusion Moderate IMR with CAD should be treated carefully. MVP with annuloplasty ring have better early results. For patients with bad heart function and abnormal left ventricular wall motion, the late results need more studies.
