Complete rupture of the anterolateral papillary muscle caused by coronary spasm.
نویسندگان
چکیده
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 valve replacement. Evidence of coronary spasm was found on a coronary vasomotion test, suggesting that a high sensitivity to coronary spasm may explain a mechanism of isolated papillary muscle infarction.

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...

Papillary muscle rupture is a lethal complication of after acute myocardial infarction. We report the successful surgical management of complete anterolateral papillary muscle rupture associated with cardiogenic shock in an 80-year-old woman. The patient was admitted with the sudden onset of chest pain and dyspnea. After hemodynamics deteriorated rapidly, she was intubated and intra-aortic ball...

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...

BACKGROUND Rupture of a papillary muscle is an infrequent but often fatal mechanical complication of acute myocardial infarction.

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...
