| 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.(Korean J Med 71:673-677, 2006)
