Subacute left ventricular free wall rupture. Surgical repair prompted by echocardiographic diagnosis

Subacute cardiac rupture may occur in patients with electrocardiographic and enzyme evidence of transmural myocardial infarction. In the unusual case we encountered, these changes were absent. The echocardiographic observation of an echo-dense area within the pericardial space, due to an organized thrombus, provided early diagnosis of cardiac rupture and prompted surgery.
