Successful percutaneous closure of ventricular septal defects associated with pulmonary hypertension using different atrial septal defect Occluders: A report of two cases

Abstract

We present two cases of children with muscular ventricular septal defects (mVSD) and severe pulmonary hypertension. Both children successfully underwent percutaneous closure using different atrial septal occluder devices. The patients were a 7-month-old boy with growth failure and cyanosis, and a 4-year-old boy with heart murmur and mild cyanosis. Their management was based on percutaneous defect closure using an Amplatzer septal occluder; Abbott Structural Heart, Plymouth, MN, USA and an Occlutech Figulla Flex-II occluder; Occlutech GmbH, Jena, Germany, respectively. Atrial septal defect occluder devices are feasible for the closure of large or atypical mVSD associated with pulmonary hypertension.

Learning objective

Information in the literature shows a brief and no clear evidence about the primary closure of congenital mVSD with atrial septal occluder devices in pediatric patients. This brief report demonstrates that this approach is a safe and effective alternative for the treatment of mVSD cases associated with pulmonary hypertension using different atrial septal occluder devices.
