Abstract: Aortopulmonary window is a rare defect caused by failure of fusion of the two opposing conotruncal ridges which are responsible for separating the truncus arteriosus into the aorta and pulmonary tract. A case of long survival with aortopulmonary window causing Eisenmenger syndrome is presented. A 65-year-old female patient was admitted with cardiorespiratory failure. She had had effort dyspnoea for 30 years but had refused investigations. Physical examination revealed generalised cyanosis, marked anasarca and a holosystolic murmur superimposed on an accentuated S2. Oxygen saturation was 95% but the arterial blood gas showed significant hypoxia (pO2 65 mmHg). Blood pressure was 150/80 mmHg. The ECG on admission showed pulmonary P-waves and signs of right ventricular hypertrophy. Echocardiography revealed a grossly dilated right ventricle with severe tricuspid regurgitation and mild pulmonary insufficiency. The estimated pulmonary pressure of 140/70 mmHg was nearly identical with the systemic blood pressure. The dimensions of the left atrium and left ventricle were within normal limits with good left ventricular systolic function.
