Ultrasonographic and Radiological Imaging Demonstrating an Anomalous Origin of the Left Coronary Artery Causing Acute Coronary Syndrome in an Adolescent
Journal of cardiology cases(2018)
摘要
We report the case of a 13-year-old girl who presented with cardiac collapse secondary to compression of the left main coronary artery (LMCA) between the pulmonary artery and the ascending aorta. In the acute phase, we performed aortography, intra-vascular ultrasound (IVUS), coronary computed tomography angiography (CCTA), transthoracic echocardiography (TTE), and transesophageal echocardiography (TEE). Aortography and CCTA showed that her LMCA was located between her pulmonary artery and the ascending aorta. IVUS and TEE showed that her LMCA was narrowed owing to compression by both great vessels during systole with release of the pressure during diastole. TTE and TEE showed that the left coronary artery flow was faster in the systole than that observed in the diastole. She was initially treated at our hospital but was transferred to another hospital for an unroofing operation. This was a rare case of a patient presenting with a coronary artery anomaly causing cardiac collapse. We conclude that her LMCA stenosis secondary to compression and narrowing of the great vessels led to her cardiac collapse. .
