Abstract:
The myocardial bridge of the coronary arteries is observed by coronary angiography at a rate of <5 % and ordinarily does not constitute a hazard. Occasionally, the compression of a coronary artery by a myocardial bridge can be associated with the clinical manifestations of myocardial ischemia during strenuous physical activity and might even result in a myocardial infarction or initiate malignant ventricular arrhythmias. A few cases of percutaneous coronary intervention for a myocardial bridge have been reported. However, there are few reports of the changes in the 2-dimensional strain in the myocardial bridge. We encountered a case of a myocardial bridge in a 48-year-old male patient who had refractory angina despite continuous medication with a beta-blocker and calcium channel blocker. The 2-dimensional strain of the patient changed after percutaneous coronary intervention with stents. We report the first case in Korea with a review of the relevant literature.
