Left ventricular free wall rupture in acute fulminant myocarditis during long-term cardiopulmonary support.
A 77-year-old woman with acute myocarditis developed cardiogenic shock soon after admission and was given mechanical cardiopulmonary support. Echocardiography revealed severe global left ventricular hypokinesia. After 5 days of mechanical support, left ventricular wall motion gradually began to improve, but the patient died of cardiac tamponade on day 13. At necropsy, a free wall rupture was found where the apical akinetic area bordered the basal portion, an area which had shown better wall motion. Left ventricular free wall rupture in acute myocarditis has not been reported, but this case indicates that it may occur in fulminant myocarditis when a cardiopulmonary support system is used.
