title: Teardrop sign: echocardiographic features in cardiac herniation.
abstract: Cardiac herniation through an acquired pericardial defect is potentially fatal. Typically, symptoms manifest within days of a surgical procedure. We describe a patient with late ventricular herniation after surgical formation of an apical pericardial window.
