[Cardiac sarcoidosis complicated by multivessel coronary spasm: a case report].
A 63-year-old woman with abnormal Q waves in leads II, III, aVF developed ventricular tachycardia after an operation for thyroid carcinoma. Coronary arteriography revealed no organic stenosis, but acetylcholine induced total occlusion of the right coronary artery and severe narrowing of the left coronary artery. Left ventriculography showed inferoposterior and septal akinesis, and echocardiography revealed slight thinning of these affected walls. She had old myocardial infarction due to spasm. One year later, she developed bilateral uveitis and recurrence of tachycardia. Cardiac sarcoidosis was diagnosed by endomyocardial biopsy. In our patient with cardiac sarcoidosis, the presence of multivessel coronary spasm made the diagnosis difficult and may have contributed to cardiac dysfunction. Coronary arteries are rarely involved, but the development of coronary spasm may be linked to sarcoidosis.
