Why the study?
Diastolic mitral regurgitation is a rare and often-overlooked form of functional mitral regurgitation.
Diastolic mitral regurgitation can be a reversible complication of acute myocardial infarction with severe heart failure.
May warrant echocardiographic consideration of diastolic MR in AMI; leaves open its prevalence and prognostic value.
Diastolic mitral regurgitation (MR) is a rare and often-overlooked form of functional MR. Key factors in the development of diastolic MR include incomplete closure of the mitral valve, reversal of left atrioventricular pressure gradient during diastole, and elevated left ventricular diastolic pressure. In this case, diastolic MR was observed in an older male patient with a single underlying pathologic condition, acute myocardial infarction. Remarkably, the diastolic MR resolved after treatment of myocardial infarction. This case highlights the importance of understanding the complex hemodynamic changes involved.
