چکیده
Mitral papillary muscle rupture is usually caused by ischaemia as a complication of myocardial infarction. In a 76 year old patient with no significant disease or major cardiovascular risk factors, papillary muscle rupture was caused by obstructive intramural coronary amyloidosis, an unusual cause.

A Case of ST-elevated myocardial infarction resulting from obstructive intramural coronary amyloidosis.
A 49-year-old man presenting with ST-elevated myocardial infarction was brought to our emergency department with AL amyloidosis. Baseline coronary angiography showed no significant stenosis of the epicardial coronary arteries, however, coronary artery angiography in response to acetylcholine and coronary flow reserve in response to papaverine were abnormal, which suggested impairment of vascula...

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...
متن کاملComplete 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...

متن کاملAnterolateral papillary muscle rupture caused by myocardial infarction: A case report
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 partia...
