A rare ventricular septal defect: a case repor

Abstract

Left ventricular-right atrial communications, known collectively as the Gerbode defect, are rare types of ventricular septal defects. Acquired forms of this defect have been described as a complication of cardiac surgery, bacterial endocarditis, chest trauma, or myocardial infarction. Diagnosis of this rare defect is challenging, but can be confirmed with echocardiography or cardiac magnetic resonance imaging. Until 6 years ago, these communications were corrected only surgically, often with relatively high mortality. However, few case reports of transcatheter closures of the defects have recently been reported with excellent results. We describe a 69-year-old patient with left ventricular-right atrial communication secondary to mitral valve surgery. The diagnosis was made by transesophageal and real-time three-dimensional echocardiography. The defect was closed percutaneously using an Amplatzer device. At follow-up, there was no residual flow and the patient improved clinically.© 2013 Il Pensiero Scientifico Editore
