Abstract

We report the case of a patient who underwent coronary angioplasty for a severe stenosis at the site of a myocardial bridge. Although favorable angiographic results and the disappearance of myocardial ischemia were obtained, a significant pressure gradient across the lesion and abnormal myocardial fractional flow reserve remained immediately following angioplasty. These results suggest that pressure measurements may be of limited value in this subset of patients.

摘要

我们报告了一例因心肌桥部位严重狭窄而接受冠状动脉血管成形术的患者。尽管血管造影结果良好且心肌缺血消失，但血管成形术后病变部位立即出现了显著的压力梯度和异常的心肌血流储备分数。这些结果表明，压力测量在这类患者中可能价值有限。
