Overview

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.
