Transcatheter closure of the aortopulmonary window in a three-month-old infant with a symmetric membranous ventricular septal defect occluder device

Although most of aortopulmonary window cases are closed surgically, percutaneous closure can be also used in suitable patients. Defects which are far from the pulmonary and aortic valves, coronary artery, and pulmonary artery bifurcation, with adequate septal rims are considered suitable for percutaneous closure. A three-month-old male infant weighing 4 kg was referred to our pediatric cardiology department with the complaints of fatigue while breastfeeding, difficulty in weight gain, heart murmur, and respiratory distress. A large aortopulmonary window (5.3 mm) and left heart chamber dilatation were detected on echocardiography. The large aortopulmonary window was closed using a symmetric membranous ventricular septal defect occluder device. The closure procedure was performed via the antegrade route without forming an arteriovenous loop. In conclusion, the use of a symmetric membranous ventricular septal defect device for closure of large aortopulmonary window seems to be a safe and effective alternative to surgery in selected infants.
