Spontaneous Resolution of Residual Shunting in 2 Compromised Patients after Amplatzer Occlusion of Postinfarction Ventricular Septal Defects

Ventricular septal defect (VSD) is a rare, potentially fatal complication of acute myocardial infarction. When surgical closure is contraindicated, transcatheter closure may be an alternative. Residual shunting after transcatheter closure of postinfarction VSDs has been reported; however, we found f...

Summary:Ventricular septal defect (VSD) is a rare, potentially fatal complication of acute myocardial infarction. When surgical closure is contraindicated, transcatheter closure may be an alternative. Residual shunting after transcatheter closure of postinfarction VSDs has been reported; however, we found few cases of this in patients who also had severe heart failure or hemolysis. We report 2 closures of postinfarction VSDs with use of the Amplatzer Septal Occluder. Both elderly patients-one with severe heart failure, one with persistent hemolysis, and neither a surgical candidate-had high-velocity residual shunting through the occluders. We intensively managed the patients' conditions and used angiography and transthoracic echocardiography to record the gradual disappearance of each shunt over 4 months-the first such serial monitoring of which we are aware. We think that even substantial shunting in the presence of severe heart failure or hemolysis can eventually resolve spontaneously, assuming effective management of the concomitant medical conditions.
