(A) Echocardiographic examination demonstrated a 3.5-4 mm wide defect between the ascending aorta and the main pulmonary artery (white arrow). (B) Color Doppler shows defect between the ascending aorta and the main pulmonary artery (white arrow). (C) Computed tomography revealed a tubular shaped APW with well-formed inferior and superior rims (white arrow). (D) Angiography shows a 4.1 mm APW at the narrowest point with a 7 mm longutidinal length. (E) Control angiogram was performed before the device was completely released. (F) Angiogram after the device was completely released. Ao, aorta; APW, aortopulmonary window; PA, pulmonary artery.
