Coronary artery disease in an 18 year old with pseudoxanthoma elasticum: successful surgical therapy.

An 18 year old girl with pseudoxanthoma elasticum, a 7 year history of angina pectoris and evidence of an old anteroseptal myocardial infarction was found on coronary angiography to have three vessel coronary artery disease. A triple coronary artery-saphenous vein bypass graft was performed, and she has been asymptomatic for 1 year. Histologic examination of a segment of the right coronary artery revealed changes consistent with the vascular lesion of pseudoxanthoma elasticum.

Variant angina pectoris: Clinical and anatomic spectrum and results of coronary bypass surgery.

Twenty patients are described with the variant angina syndrome (recurrent angina at rest with S-T segment elevations occurring only during pain and no evolution of infarction). In contrast to patients previously reported on, all but one had progressive unstable angina before hospitalization. Angina was frequently associated with arrhythmias, including ventricular fibrillation (2 instances), ventricular tachycardia (4), frequent ventricular premature beats (5), atrioventricular block (4), sinus bradycardia (2), sinoatrial exit block (1) and supraventricular tachycardia (1). Seventeen patients had significant proximal stenosis of one or more coronary arteries with good distal vessels. Bypass surgery in 15 of these patients resulted in one noncardiac postoperative death, one perioperative infarction and relief of pain in all 14 survivors. After a 17 month mean follow-up period (range 4 to 38 months), all survivors are pain-free. Three patients had no significant coronary disease; one of these became asymptomatic with medical therapy, one continues to have angina and one died suddenly. Patients with normal coronary arteries could not be distinguished clinically or by electrocardiogram from those with severe obstructive lesions. This experience suggests that all patients with the variant angina syndrome should be studied by coronary angiography, and that most patients with significant fixed coronary lesions will do well after coronary bypass surgery.
