Objectives & ( hypothesis OR questions) : Ischemic mitral regurgitation (IMR) is a major source of morbidity and mortality of myocardial infarction. Although mitral valve repair has become recently popularized for the treatment of IMR, select patients may derive benefits from replacement. The purpose of this study is to describe current surgical options for IMR and to discuss when mitral valve repair (MVR) by KAY method may be favored over mitral valve replacement. Materials & Methods: This clinical study was conducted from 28 may 2014 to 2016-05-28 ,in cardiac surgery ward of Imam Reza Hospital of Mashhad University of Medical Sciences retrospectively. All of patients with ischemic mitral regurgitation (moderate or severe) who needs CABG planned CABG +Mitral Repair and KAY method had been chosen .and all patients follow –up for One year by admission and echocardiography in day of discharge -3 months and 1 year ago. Operation and echocardiography was done by same cardiac surgeon and cardiologist. Results: We found 12 patients (male=5,femal=8) that operated by CABG AND KAY METHOD ,IN 75% of them was a history of previous myocardial infarction and in remainder there was acute ischemia of myocardium. In 91/7% patients there was inferior myocardial infarction and dominant coronary vessel was RCA.ALL of patient had significant MR that resolved in all of them (p-value. (0.05> there isn’t any preoperative and post operative mortality. The main time of CPB was 150 minute and in t2 test revealed 10% increased ejection fraction of left ventricle (p value <0/0005).no further postoperative reported in 1 year follow-up patients. Conclusion :Although surgical CABG alone may benefit patients with mild–moderate IMR, most surgeons advocate the performance of CABG in combination with either mitral valve repair or replacement. In the current era, and in Iran mitral valve repair specially KAY method has proven to offer improved short-term and long-term survival, decreased valve-related morbidity, and improved left ventricular function and it is cost effective procedure. Future randomized, prospective clinical trials are needed to compare this surgical technique.
