Although myocardial bridge is not thought to have any hemodynamic significance in most cases, some have suggested that when it produces severe systolic narrowing, ischemia or infarction may result. Myocardial bridge in adults with hypertrophic cardiomyopathy may be associated with a higher incidence of sudden death, myocardial wall-motion abnormalities, and perfusion defects on thallium-201 scintigraphy. When myocardial bridge is associated with left ventricular hypertrophy, it is known to

We report a case of hypertrophic cardiomyopathy with myocardial bridge at the middle part of the left anterior descending coronary artery, who also showed reversible perfusion defect on the thallium scan at the same coronary territory.
