Abstract
Objective To explore the value of 64-slice MSCT in diagnosing anomalous origin of the left coronary artery from the pulmonary artery. Methods Seven infants with anomalous origin of the left coronary artery from the pulmonary artery, diagnosed with 64 MSCT and proven by surgery or autopsy, were retrospectively reviewed. Results The opening orifice of the left coronary artery in pulmonary artery was shown by 64 MSCT in all 7 infants with 3 cases arising from the right lateral wall, 1 case from the left lateral wall, 1 case from the left posterior lateral wall and 2 cases from the posterior sinus of pulmonary artery. In 7 cases, the origin of the right coronary artery was normal and all were originated from the right sinus of Valsalva of aorta, the right coronary artery was turtuous and dilated in 4 cases. Conclusion 64 MSCT is emerging as an essential imaging tool for detecting early anomalous origin of the left coronary artery from the pulmonary artery with high resolution and significance.
