Echocardiography plays a crucial role in the rapid diagnosis and prompt surgical referral required for optimal outcomes in patients with papillary muscle rupture following acute myocardial infarction.
Emphasizes urgent echocardiography for post-MI papillary muscle rupture; leaves open need for prospective validation before guideline changes.
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. Comprehensive echocardiographic examination of the patient with PM rupture consists of identification of the ruptured PM segment, visualization of flail mitral valve segment(s), evaluation of mitral regurgitation severity, and assessment of left ventricular systolic function. This article discusses anatomic and echocardiographic features as well as the surgical management of PM rupture.
