BACKGROUND: Unilateral absence of a pulmonary artery is a rare congenital
abnormality with few reports in the literature demonstrating resultant myocardial
ischaemia. CASE SUMMARY: A 59-year-old presented with acute coronary syndrome
(ACS). She was known to have right-sided pulmonary atresia. She was found to have
angiographically normal looking coronary arteries but had left circumflex to
right lung (via bronchial artery) fistula. Stress echocardiography demonstrated
significant ischaemia in that territory, which resolved after coil embolization
of the fistula. DISCUSSION: To our knowledge, this is the first reported case of
ACS secondary to steal phenomena due to circumflex-pulmonary fistula and treated
successfully with coil embolization.
