In two infants the anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) was detected prospectively by transoesophageal echocardiography (TEE). Colour flow mapping and pulsed Doppler ultrasound revealed a predominant right-to-left shunt from the pulmonary artery to the left coronary artery. These findings were confirmed by angiography. Transthoracic echocardiography (TTE) failed to show the anomalous origin of the left coronary artery or any abnormal pulmonary flow pattern. TEE may be useful in the diagnosis of ALCAPA in selected cases, when TTE is inconclusive.
在两名婴儿中，经食管超声心动图（TEE）前瞻性地检测到左冠状动脉起源于肺动脉（ALCAPA）。彩色血流图和脉冲多普勒超声显示从肺动脉到左冠状动脉存在明显的右向左分流。血管造影证实了这些发现。经胸超声心动图（TTE）未能显示左冠状动脉的异常起源或任何异常的肺血流模式。当TTE结果不明确时，TEE可能有助于某些病例中ALCAPA的诊断。
