[Ischemic reaction in a young woman without coronary sclerosis: Bland-White-Garland syndrome].

A 39-year-old woman, with known mild mitral regurgitation, developed progressively more severe symptoms of angina, associated with an ischaemia response in the exercise electrocardiogram. Angiocardiography demonstrated an anomalous origin of the left coronary artery from the pulmonary artery (Bland-White-Garland syndrome). At operation an aortocoronary venous bypass graft was constructed; the patient has been without symptoms since and the exercise ECG is normal. As demonstrated by angiography, the previously marked dilatation of the right coronary artery had largely regressed and previously present collaterals to the left coronary artery were no longer visualized three months after operation. The described coronary artery anomaly, although rare, should be considered in a young patient with reproducible coronary artery ischaemia.
