A Case Report: Atrioventricular Block Secondary to Ruptured Sinus of Valsalva Aneurysm in A 12-Year-Old

Ruptured aortic sinus of Valsalva aneurysm is a rare cardiac anomaly that can lead to life-threatening complications. We present a case of a 12-year-old girl with complete heart block, who presented with these symptoms and was diagnosed with a ruptured aortic sinus of Valsalva aneurysm dissecting into the interventricular septum, with probable compression of the conduction system. Echocardiography and AngioTDM confirmed the diagnosis, and the anomaly was successfully managed percutaneously by closing the orifice of communication using a ventricular septal defect (VSD) muscular occluder. Follow-up examinations showed no flow inside the aneurysm, indicating a successful closure procedure. This case highlights the importance of early diagnosis and prompt intervention in managing ruptured aortic sinus of Valsalva aneurysm in pediatric patients.
