Myocardial Bridging as Cause of Myocardial Infarction: Report of Case

We present a patient who developed myocardial infaretion and finally left ventricular heart failure due to myocardial bridging. A 65-year-old male patient with diabetes mellİtus was admitted to the emergency department due to acute pulmonary edema. The patient had exertİonaJ dyspnea for 4 years, but did not have typical angina complaints. On ECG there was sİnus rhythm and incomplete left bundle-branch block. Echocardiography revealed lateral h ypokİ n esİa, mid and apİcal anteroseptal akİ nesia and an ap İca l aneurysm wİth probable mural thrombus. At coronary angiography myocardİal bridging was observed in a long segment of the mid-portion of left anterİor descendİng artery. Other coronary arteries were normal. Resting myocardial perfusion scintigraphy w ith Tl-20 1, disclosed a fixed perfusion defect matching with the distal part of the bridging. The patİent recİeved medical treatment for heart fai lure and died a sudden after recurrent hospitalizations.
