Anterolateral papillary muscle rupture caused by myocardial infarction: A case report
نویسندگان
چکیده
BACKGROUND The rupture of the anterolateral papillary muscle is less common than the posteromedial papillary muscle since the anterolateral muscle has dual blood supplies, while the posteromedial papillary muscle has a single blood supply. CASE PRESENTATION We present a case report of a 42 year old male presenting with heart failure being diagnosed to have mitral regurgitation from the partial rupture of the anterolateral papillary muscle due to coronary artery disease. The patient underwent a mitral valve replacement and concomitant coronary artery bypass grafting of the first and the second obtuse marginal arteries. CONCLUSION Acute mitral regurgitation can be precipitated by acute myocardial infarction due to rupture of the anterolateral papillary muscle.

Complete rupture of the anterolateral papillary muscle caused by coronary spasm.
Papillary muscle rupture usually occurs as a catastrophic complication of acute myocardial infarction in patients with coronary artery stenosis; it is therefore less common in patients without coronary artery stenosis. We report the case of a 67-year old woman without coronary artery stenosis who suffered an acute anterolateral papillary muscle rupture and was successfully treated with mitral v...

A rare complication of AMI is papillary muscle rupture (PMR), occurring in 1% of patients with acute myocardial infarction (AMI). Mitral regurgitation related to PMR occurs at a median of 1 day (ranging from 1-14 days) after onset of myocardial infarction. PMR tends to occur in those having a first time AMI and those without extensive collateral circulation. PMR involves posteromedial papillary...

Ischemic rupture of the anterolateral papillary muscle is uncommon due to its dual blood supply. It usually follows an ischemic event involving branches of the left circumflex or left anterior descending arteries. We present a case of a patient admitted with an acute inferior wall myocardial infarction and an isolated distal right coronary artery occlusion. Acute mitral regurgitation with ruptu...

Left ventricular free wall rupture and acute ischaemic mitral regurgitation are nowadays rare, but still potentially lethal mechanical complications after acute myocardial infarction. We report a case of a sequential left ventricular free wall rupture, anterolateral papillary muscle disruption, secondary severe mitral regurgitation and subsequent posteromedial papillary muscle head rupture in a...

BACKGROUND Rupture of a papillary muscle is an infrequent but often fatal mechanical complication of acute myocardial infarction. AIM The aim of this paper is to present a case report of a 65-year old women with acute severe mitral regurgitation with cardiogenic shock caused by two-step complete anterior papillary muscle rupture during acute myocardial infarction. The transthoracic echocardio...
