Abstract :

Introduction: The incidence of coronary artery disease is on the rise in both urban and rural sections in India. Ischemic Mitral Regurgitation is one of the complications of coronary artery disease and is an independent prognostic factor in chest pain.We aimed to study various factors contributing to the mechanism of Ischemic Mitral Regurgitation (IMR) using 2Dechocardiography among patients with recent myocardial infarction.

Methodology: A comparative cross sectional study was carried out among 30 patients with recent myocardial infarction visiting our hospital for their follow up. Echocardiographic. and tissue Doppler echocardiography was done for all patients.The study participants were divided into two groups Group A had recent anterior wall myocardial infarction and Group B had recent inferior wall myocardial infarction. Group B participants were further subdivided into 2 groups based on their left ventricular spherecity into B1 and B2.

Results: The average left ventricular ejection fraction is higher in group B2 compared to group B1 and A (p<0.01). The incidence of moderate to severe mitral regurgitation is high in group B1 and A compared to B2 (p <0.01).The LV dysfunction of group B1 Vs B2 and all cases in mild and mod–severe MR were statistically significant (p <0.05).

Conclusion:There is a central role of leaflet tethering in the mechanism responsible for ischemic MR. Therapeutic approaches to relieve ischemic MR need to be targeted to reduce tethering by LV remodeling. Surgical approaches can be targeted at relieving tethering by aneurysm application and repositioning of Papillary muscles
