AB - Papillary muscle rupture is a rare complication of myocardial infarction. Here we describe a case of an
apparently spontaneous rupture of papillary muscle, not associated with coronary obstruction. The patient
was a 73-year-old man admitted to our hospital for diabetic ketoacidosis complicated by acute pulmonary
edema and cardiogenic shock. Transthoracic and transesophageal echocardiography showed partial rupture
of papillary muscle leading to severe mitral regurgitation. Urgent cardiac surgery with mitral valve
replacement was performed.
