摘要

一名先前健康的九岁男孩患有左冠状动脉主动脉起源异常(AAOLCA),具有高风险解剖结构,在磁共振成像上表现出负应力。进行了有创心导管插入术测量冠状动脉内流量,并证明在药物应激期间冠状动脉流量受损,血管造影术显示严重狭窄。患者接受了手术干预,术后评估冠状动脉血流正常化。在无创灌注研究呈阴性的高危AAOLCA患者中,在挑衅性压力下通过血管造影术确定有创冠状动脉内血流正成为风险分层和管理决策的关键数据点。

Invasive Coronary Assessment in a 9-Year-Old With Anomalous Aortic Origin of the Left Coronary Artery.

A previously healthy nine-year-old boy with anomalous aortic origin of the left coronary artery (AAOLCA) with high-risk anatomy demonstrated negative stress on magnetic resonance imaging. Invasive cardiac catheterization for intracoronary flow measurement was performed and demonstrated compromised coronary flow during pharmacologic stress and significant stenosis on angiography. The patient underwent surgical intervention with normalization of coronary flow upon postoperative evaluation. Invasive intracoronary flow determination with angiography under provocative stress is emerging as a critical data point for risk stratification and management decision-making in high-risk AAOLCA patients with negative noninvasive perfusion studies.
