title: Catheter interventional closure of a large right pulmonary artery-to-left atrial communication in a neonate.
abstract: Right pulmonary artery-to-left atrial communication is a rare congenital vascular malformation that results in a right-to-left shunting. This report describes the case history of a neonate with a large right pulmonary artery-to-left atrial connection resulting in cyanosis and severe heart failure who underwent successful early catheter interventional therapy. In the neonate, this lesion can be diagnosed accurately using transthoracic echocardiography. Closure of the communication can be achieved even in infants via percutaneous interventional catheterization with a low procedure-related risk and a good midterm follow-up result.
