ANOMALOUS ORIGIN OF EITHER RIGHT OR LEFT MAIN CORONARY ARTERY FROM THE AORTA

左冠状动脉主干(LMCA)异常起源或 右冠状动脉(RCA)与随后的走行 是一种罕见的，有时甚至是致命的 冠状动脉异常。我们回顾了这些异常中的32例。 要特别注意它的确切位置和形状 位置异常的开口和冠脉优势。LMCA 7例起源于右冠状静脉窦后(6例) 情况)或作为单个开口，RCA横跨在左右两侧 右冠状静脉窦连合部1例。在7个国家中的5个 病例中，异常是致命的。肾小球异常起源6例 LMCA、RCA占优势，4例为致死性异常。在……里面 左回旋支LMCA起源异常仅1例 冠状动脉占主导地位，在这种情况下，异常也是 致命的。右冠状动脉(25例)发生于左后方 冠状静脉窦8例，左冠状静脉窦以上5例， 从右-左连合上方(10例)或作为单个 左右连合上方和左侧有LMCA的开口 冠状静脉窦2例。在这25例中，有8例异常是 致命的。7例右冠状动脉起源异常中，左侧 冠状动脉回旋支占优势，1例异常 具有重要的临床意义。在1例中，RCA和Left都 回旋支冠状动脉发育不良，异常为 致命的。冠状优势，而不是口部形状，在 将临床上有意义的与临床上有意义的 微不足道的异常。

Anomalous origin of either the left main coronary artery (LMCA) or right coronary artery (RCA) from the aorta with subsequent coursing between the aorta and pulmonary trunk is a rare and sometimes fatal coronary artery anomaly. We reviewed 32 cases of these anomalies with particular attention to the exact location and shape of the anomalistically positioned ostium and coronary dominance. The LMCA (7 cases) arose either from behind the right coronary sinus (6 cases) or as a single ostium with the RCA stradding the right-left commissure and right coronary sinus (1 cases). In 5 of the 7 cases, the anomaly was fatal. In 6 cases of anomalous origin of the LMCA, the RCA was dominant and in 4 the anomaly was fatal. In only 1 case of anomalous origin of the LMCA, the left circumflex coronary artery was dominant and in this case the anomaly also was fatal. The RCA (25 cases) arose either from behind the left coronary sinus (8 cases), above the left coronary sinus (5 cases), from above the right-left commissure (10 cases), or as a single ostium with the LMCA above the right-left commissure and left coronary sinus (2 cases). In 8 of these 25 cases the anomaly was fatal. In 7 cases of anomalous origin of the RCA, the left circumflex coronary artery was dominant and in 1 the anomaly was clinically significant. In 1 case, both the RCA and left circumflex coronary artery were hypoplastic and the anomaly was fatal. Coronary dominance, not ostial shape, was useful in separating the clinically significant from the clinically insignificant anomalies.
