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.
