[Multiple coronary artery-left ventricle fistulas in a patient with apical hypertrophic cardiomyopathy: an unusual cause of angina pectoris].
A 50 year-old man had a history of crescendo exertional angina. Echocardiographic and electrocardiographic findings were typical of apical hypertrophic cardiomyopathy. Selective coronary angiography showed no atherosclerotic lesions, but there was a stream of dye into the left ventricle, via a tiny plexus of intramural vessels, from the distal third of the anterior descending coronary artery. The origin of myocardial ischemia has been related to a "steal" phenomenon, while this vascular anomaly could represent a disorder of the thebesian system, possibly due to the "disarray" of myocardial cells typical of hypertrophic cardiomyopathy.
