Aortopulmonary window (APW) is a rare congenital cardiac anomaly, which clinically mimics patent ductusarteriosus (PDA). A girl who was diagnosed tohave congenital heart disease (CHD) at the age of four years presented to us at the age of 10 years with exertional dyspnoea and fatigue. She was clinically diagnosed as PDA with pulmonary artery hypertension (PAH) Two-dimensional and colour Doppler echocardiography showed a type II aortopulmonary window and a large inlet type of subpulmonic ventricular septal defect (VSD) with non-compaction of left ventricle. The diagnosis was confirmed by cardiac catheterization and angiography. This is an interesting case of type II APW with rare association that can be missed clinically, but can be diagnosed by meticulous echocardiogram. We herein report a rare case of aortopulmonary window associated with a subpulmonic ventricular septal defect and leftventicle non compaction (LVNC).
