Title

Correlation between echocardiographic severity of ischemic mitral valve regurgitation following acute myocardial infarction and its electrocardiographic location

Pages

  169-173

Abstract

 Introduction: Ischemic Mitral Regurgitation (IMR) is common after acute Myocardial Infarction (AMI) which is associated with long-term cardiovascular mortality. Size, transmurality and location of the Myocardial Infarction (MI) has role on the development of IMR. In this study we evaluated the severity of IMR after different types of MI. Methods: One-hundred patients with the first AMI were recruited and according to echocardiographic findings were categorized to have moderate to severe IMR (case group, n=50) or trivial or no IMR (control group, n=50). Demographic and echocardiographic findings and MI location were compared between groups. Results: Case group compared to control group had significantly higher Killip class, more cases with left ventricular ejection fraction (LVEF) <30% and inferolateral STEMI. They had significantly higher left ventricular (LV) and right ventricular (RV) diastolic dysfunction. Mechanism of IMR was mono leaflet tethering in 88%, both leaflets tethering in 12% and ring dilatation in 62%. MR jet origin-direction was medial commisure-posterior in 66%, lateral commisure-anterior in 11 22% and both commisure-central direction in 12%. Conclusion: IMR is common after AMI, especially in cases with inferior MI. The echocardiographic findings are indicative of left ventricular remodeling and abnormality of mitral valve apparatus.
