Percutaneous closure of congenital Gerbode defect using Nit-Occlud® Lê VSD coil

Abstract

We present a case report about percutaneous closure of a congenital Gerbode defect using Nit-Occlud^® Lê VSD coil. The patient was referred to our hospital with a diagnosis of ventricular septal defect (VSD) and severe pulmonary arterial hypertension. But transthoracic echocardiography revealed a communication between the left ventricle (LV) and the right atrial (RA), called Gerbode defect. Catheterization confirmed the shunt from the LV to the RA. We successfully closed the defect with a VSD coil. After uneventful 6 mo follow-up, the patient was out of dyspnea, the symptom urged him to have medical attention. This case report is to discuss the diagnosis and percutaneous treatment approach for this rare congenital heart disease.

Core tip: Congenital Gerbode defect is rare, only accounts for about 0.08% among congenital heart diseases. The diagnosis is easily misinterpreted with others condition on clinical examination and echocardiography. The treatment of this disease is also lack of recommendation. There are several approaches can be applied for this kind of defect such as conservation, cardiac surgery, intravascular intervention or intraoperative device closure. There are several devices can be used for transcatheter closure such as ventricular septal occluder, atrial septal occluder, ADO I or ADO II. This is the first report using Nit-Occlud^® Lê VSD coil to close Gerbode defect successfully.
