Abstract

Background: Transcatheter closure of intracardiac defects might be complicated by intravascular hemolysis. We evaluated hemolysis and its outcome after transcatheter closure of these defects.

Methods and patients: All patients who underwent transcatheter closure of patent ductus arteriosus, ventricular septal defect and atrial septal defect were included in this prospective study. Clinical data were obtained before and after the catheterization.

Results: One hundred and thirty-eight patients were enrolled; and four (3%) patients developed intravascular hemolysis; while two cases had residual shunt and two other cases had not residual flow. Although residual shunt occurred in ten patients, only 2 of these cases developed hemolysis. Patent ductus arteriosus closure was done for one of these cases and the other one, underwent perimembranous ventricular septal defect closure. Moreover, hemolysis occurred after device closure of patent ductus arteriosus in 2 of the other patients with no residual shunt. In this study the hemolysis was eliminated by conservative management within 2 weeks although residual shunt continued in this time. We observed a decline in lactate dehydrogenase value after catheterization in comparison with precatheterization, which was mainly among ventricular septal defect patients that might be due to mild chronic hemolysis in these patients.

Conclusion: Incidence of hemolysis after device closure was low, and occurred with and without residual flow and was eliminated by conservative management in 2 weeks, without the need for surgery, although the residual shunt was continued.
