[Bland-White-Garland syndrome in an adult].

We report about a 47-year-old woman, who presented with a history of cardiac failure. Echocardiography showed an impaired left ventricular function, clinically significant mitral regurgitation and pulmonary hypertension. Diagnosis of a Bland- White-Garland syndrome was made by coronary angiography. Subsequent therapy consisted of ligation of the anomalus origin of the left coronary artery, implantation of a Mammaria interna graft to the left coronary artery and replacement of the mitral valve by a mechanical prosthesis. One year after operation, left ventricular function was still impaired. At a 3-year follow-up, left ventricular function improved continuously.
