| dc.description.abstract | Introduction. Transcatheter closure has become an increasingly common non-surgical intervention for Ventricular Septal Defect (VSD), Atrial Septal Defect (ASD), and Patent Ductus Arteriosus (PDA). However, data on the characteristics of patients undergoing transcatheter closure in North Sumatra remain limited. Objective. This study aimed to describe the demographic and clinical characteristics of pediatric patients undergoing transcatheter closure procedures. Methods. A retrospective descriptive study was conducted using medical records of pediatric patients with congenital heart disease who underwent transcatheter closure at Adam Malik General Hospital, Medan. Patient characteristics including sex, age, nutritional status, clinical presentation, defect type and size, and occluder device type were analyzed. Results. A total of 108 patients met the inclusion and exclusion criteria. The majority were female (54,6%) and aged 12-59 months (50,9%), with normal nutritional status (52.8%). VSD was the most common defect (68,5%), predominantly of moderate size (57,4%). Most patients were classified as ROSS/NYHA class II (70,4%). The AMVO occluder was the most frequently used device (67,6%), with size 8/6 being the most common. Conclusion. Most pediatric patients undergoing transcatheter closure were female, aged 1–3 years, had normal nutritional status, and presented with moderate VSD classified as ROSS/NYHA class II. The AMVO occluder, particularly size 8/6, was the most frequently utilized device. | en_US |
