title: Negative remodeling at the ostium of the left anterior descending artery induced myocardial ischemia.
abstract: We report a case of a patient with exertional angina whose coronary angiography showed a severe stenosis at the ostium of the left coronary anterior descending artery. However, intravascular ultrasound imaging demonstrated only mild plaque burden and negative remodeling, with a 0.66 ratio of external elastic membrane area of the lesion to the distal site. The lesion was successfully treated with stenting. Therefore, our case suggests that negative remodeling at an ostial lesion could be the primary cause of myocardial ischemia.
