Why the study?
Papillary muscle rupture is a rare but fatal complication of acute myocardial infarction requiring accurate assessment for medical management and determining surgical or percutaneous treatment.
Echocardiography plays a crucial role in identifying the characteristics of papillary muscle rupture to guide appropriate medical, surgical, or percutaneous treatment.
Echocardiography enables prompt diagnosis of post-MI papillary muscle rupture; leaves open optimal management strategies in shock.
Papillary muscle rupture is a rare but fatal complication of acute myocardial infarction. The incidence of this complication has been reduced to less than 0.1% of patients due to the advent of primary percutaneous coronary intervention. Cardiogenic shock and acute pulmonary edema are the most common clinical presentations. In this review, we describe the role of transthoracic and transesophageal echocardiography in identifying the type, location, and hemodynamic consequences of the three different echocardiographic patterns of papillary muscle rupture. This information is crucial for managing medical therapy and determining the appropriate surgical or percutaneous treatment.
