Although an increase in diastolic coronary flow velocity can be detected by transesophageal echocardiography 72 hours after both successful and unsuccessful left anterior coronary artery angioplasty, a significant improvement in coronary flow reserve is observed only in patients with a successful procedure. Transesophageal echocardiography-derived coronary flow reserve can identify early restenosis and thus serve as an index of the outcome of the procedure.
尽管在左前冠状动脉血管成形术成功与失败后72小时，经食管超声心动图均可检测到舒张期冠状动脉血流速度增加，但仅在手术成功的患者中观察到冠状动脉血流储备有显著改善。经食管超声心动图得出的冠状动脉血流储备可识别早期再狭窄，从而作为该手术结果的一个指标。
