Papillary muscle rupture overview

Papillary muscle rupture is an infrequent mechanical complication of acute myocardial infarction. Early diagnosis is important so that surgical repair can be performed.

Acute mitral regurgitation secondary to left ventricular papillary muscle rupture or chordae tendineae rupture, is a medical and surgical emergency. Patients may present with acute pulmonary edema or cardiogenic shock and most often the required and definitive treatment is valvular surgery. However, medical therapy may be needed to stabilize the patient until surgery can be performed.
