We describe 3 patients with suspected subacute cardiac rupture in whom contrast-enhanced echocardiography played a key role in the diagnosis. In 2 patients, extravasation of the contrast material into the extracardiac space provided direct evidence of subacute cardiac rupture. Absence of this feature helped to exclude cardiac rupture with active ...
