Acute rupture frequently results in severe mitral valve regurgitation and subsequent acute life-threatening cardiogenic shock and pulmonary edema.
A 52-year-old man presented with acute onset of chest pain and was found to have an inferolateral ST-segment elevation myocardial infarction and acute mitral regurgitation due to papillary muscle rupture. This case describes a rare, potentially fatal mechanical complication of acute myocardial infarction. (Level of Difficulty: Beginner.)
Papillary muscle rupture (PMR) is a rare mechanical complication post-acute myocardial infarction (MI). It affects 0.07–0.26% of patients following MI and accounts for 5% of mortality after an infarct (1, 2). It results in severe mitral valve regurgitation (MR), which is often accompanied by cardiogenic shock and pulmonary edema, requiring ...
6 mar 2023 · Spontaneous, non-ischemic papillary muscle rupture (PMR) is a rare and life-threatening cardiac emergency. As a rare form of acute heart failure and hemodynamic compromise, urgent evaluation and diagnosis is needed as PMR is often fatal unless emergent repair or valve replacement is instituted.
Papillary muscle (PM) rupture is a rare complication of acute myocardial infarction which carries an excessive mortality rate. Optimal outcomes require rapid diagnosis and prompt surgical referral, and in this regard, echocardiography plays a crucial role.
28 gru 2023 · Ischaemic rupture. Papillary muscle. The mitral valve leaflets are supported through the papillary muscle projections from the left ventricular wall and their tendinous cords which extend to the leaflet margins and the belly of the leaflets (Fig. 4.1).
