Abstract :
Myocardial bridging is a common and usually benign inborn coronary anomaly. We report on a 51-year-old man who presented with recent angina on minimum physical effort. Cineangiography showed myocardial bridging of the mid-left anterior descending artery (LAD), and intracoronary ultrasonography excluded atherosclerotic disease. Gated single-photon emission computed tomography (SPECT), with exercise stress, showed an extensive anterior perfusion defect, and remarkable ST-segment elevation (up to 10 mm) in recovery. Vasospasm of the LAD was the main hypothesis. Additional oral drugs did not bring about improvement, as indicated on a new SPECT; disabling angina persisted. Surgical revascularization of the LAD by left internal mammary artery graft was performed. Two years later, SPECT and exercise tests returned to normal. The patient remains asymptomatic.
