Right coronary myocardial bridging: An extremely rare case

Published:December 24, 2022DOI:
      A 63-year-old man, asymptomatic for typical angina, underwent coronary angiography before elective surgery repair of ascending aorta aneurysm and aortic valve insufficiency. The coronary angiography showed systolic compression of the right coronary posterolateral artery which narrowed completely during systole (Fig. 1, video 1 and 2). The patient underwent implantable cardioverter defibrillator in primary prevention due to dilated cardiomyopathy a year ago. Electrocardiogram (ECG) showed only negative T waves in V5-V6. Transthoracic echocardiography showed diffuse hypokinesis with reduced ejection fraction (34%). Relevant laboratory tests were normal.
