Pulmonary arteriovenous malformations are rare vascular anomalies which rarely present in childhood. We discuss a nine-year-old male child who presented with the classical triad of exertional dyspnea, cyanosis and clubbing since six years of age. Pulmonary arteriovenous malformation was suspected on chest radiography and was later confirmed on computed tomography scan. A bubble contrast echocardiography showed the presence of an extracardiac shunt. Pulmonary angiography was done to delineate the anatomy of the pulmonary vasculature and to plan embolization. The child has undergone two sittings of transcatheter coil embolization with improvement in oxygenation.
