TRANSCATHETER CLOSURE OF LARGE PERSISTENT DUCTUS ARTERIOSUS WITH THE MUSCULAR VENTRICULAR SEPTAL DEFECT DEVICE

Abstract

Objective: To assess the efficacy of Ventricular Septal Defect device for occlusion of large Patent Ductus Arteriosis with high pulmonary artery pressure.

Study Design: Descriptive cross-sectional study.

Place and Duration of Study: Armed Forces Institute of Cardiology Rawalpindi from May 2014 to Dec 2017.

Material and Methods: It was a descriptive cross-sectional study included seventy patients. Patients more than 2 months of age were included. Patients with large PDAs and systemic or near systemic pulmonary artery pressure underwent transcatheter closure using the VSD (SHSMA). Patients had weight less than 3kg were excluded. All patients were followed by echocardiogram 2 weeks and 6 months following the procedure.

Results: The mean echocardiographic and angiographic PDA diameter was 8.5 mm (1.8) (range 5-14 mm) and the mean VSD diameter was 11.4 (1.8) mm (range 9-16 mm). Successful device delivery and complete closure occurred in 55 patients (96.5% occlusion rate), Mean systolic pulmonary artery pressures was 65 mm Hg before procedure and 39 mm Hg immediately after the procedure. Fluoroscopy time was 9 min (range 5-25 min). Two devices embolized.

Conclusions: VSD device is very effective for closure of large PDAs along with high pulmonary artery pressure.
