Overview

Myocardial rupture is a laceration or tearing of the walls of the ventricles or atria of the heart, of the interatrial or interventricular septum, of the papillary muscles or chordae tendineae or of one of the valves of the heart. It is most commonly seen as a serious sequelae of an acute myocardial infarction (heart attack).

Pathophysiology

The most common cause of myocardial rupture is a recent myocardial infarction, with the rupture typically occurring three to five days after infarction. Other causes of rupture include cardiac trauma, endocarditis (infection of the heart),[1][2] cardiac tumors, infiltrative diseases of the heart,[1] and aortic dissection.
