A myocardial bridge is a congenital anomaly in which a segment of the coronary artery tunnels under the bridge of the overlapping myocardium. This causes the vessel to contract during systole, resulting in hemodynamic changes that can be associated with angina pectoris, myocardial ischemia, acute coronary syndrome, left ventricular dysfunction, arrhythmias, and sudden cardiac death. Beta-adrenoblockers and calcium channel blockers are the first-line therapy to eliminate the symptoms of a tunneled coronary artery. Surgical tactics (myotomy, intracoronary stenting, or aortocoronary bypass surgery) is indicated for refractory symptoms. A method for pharmacological correction of a verified myocardial bridge in the coronary artery is presented in our clinical case.
