“…The present study found that anterior and anterolateral walls were most prevalent MI territories in IMR and no MR patients. Quinn et al [24] found that 9% cases of moderate to severe MR were reported in 234 patients and 17% in 242 patients of inferoapical extension. In our study, left ventricular ejection fraction >55% were mostly found in no MR patients whereas left ventricular ejection fraction <35% observed in IMR.…”

Background and Aim: Ischemic mitral regurgitation (IMR) is the most prevalent complication following myocardial infarction (MI) and coronary artery disease. Acute or chronic MI can lead to IMR resulting from an abnormality in regional wall motion or dysfunction of papillary muscles in a territory with structurally normal mitral valve leaflets, coronary artery disease and chordae tendineae. The present study aimed to determine the incidence of ischemic mitral regurgitation in ST elevation myocardial infarction and its impact on hospital course. Material and Methods: This cross-sectional study was conducted on 164 myocardial infarction patients in the Department of Cardiology of Pakistan Institute Medical Sciences Hospital, Islamabad over a time period of 6 months. Institute research and ethical committee approved the study protocol. Patients with prior mitral surgery, heart failure, previous myocardial infarction, and mitral valve disorders were excluded. Demographic detail, echocardiographic parameters, and myocardial complications were recorded. Other parameters such as Killip class, in-hospital mortality, and MI territory with respect to electrocardiographic changes were recorded. Data analysis was carried out in SPSS version 26. Results: Of the total 164 MI patients, there were 114 (69.5%) male and 50 (30.5%) females. The overall mean age was 58.62±8.62 years. The incidence of IMR was 106 (64.6%), out of which the prevalence of mild, moderate, and severe MR were 86 (81.1%), 12 (11.3%), and 8 (7.6%) respectively. No significant association was found between the presence of IMR and other parameters such as diabetes, smoking, hypertension, gender, and BMI. There was a significant association between triglyceride and serum LDL-cholesterol levels with IMR presence. On comparing the IMR and no MR cases, left ventricular ejection fraction reduced but pulmonary arterial pressure increased in IMR groups. Conclusion: The present study found that the prevalence of IMR was 64.6% among MI patients and approximately half of the patients who suffer from IMR after having an AMI experience complications as a result of it. A proper treatment decision depends on assessing the severity of the MR in relation to AMI complications. Keywords: Ischemic mitral regurgitation, Myocardial infarction, ST elevation

“…The translation of these repair techniques in the context of acute IMR are anticipated. Other novel techniques, such as mitral valve translocation surgery in IMR, have been developed in an attempt to overcome the long-term durability concerns of traditional mitral valve repair techniques [ 78 ]. The early experience with this method is limited to chronic IMR; however, further studies are warranted before conclusions relating to its efficacy in the setting of acute IMR can be made.…”

Acute ischaemic mitral regurgitation (IMR) is an increasingly rare and challenging complication following acute myocardial infarction. Despite recent technical advances in both surgical and percutaneous interventions, a poor prognosis is often associated with this challenging patient cohort. In this review, we revisit the diagnosis and typical echocardiographic features, and evaluate current surgical and percutaneous treatment options for patients with acute IMR.
