| 中文摘要 | 先天性無主冠狀動脈是一種極為少見的冠狀動脈異常,除了無左冠狀動脈開口,左主幹近端無連接,右冠狀動脈血流會經由側枝循環回到至少一條左側冠狀動脈。我們描述一位五十歲男性呈現不典型胸痛但因運動心電圖異常接受冠狀動脈攝影及六十四切電腦斷層攝影清楚顯示無左主冠狀動脈,左前降枝次左迴旋枝之近端變小及明顯的由右冠狀動脈至左側血管的側枝循環,六十四切電腦斷層攝影可以提供對複雜的先天冠狀動脈異常清晰的解剖學影像。 |
| 英文摘要 | Congenital atresia of the left main coronary artery (LMCA) is a rare coronary anomaly in which there is no left coronary ostium, the proximal left main trunk ends blindly and blood flows from the right coronary artery to the left via small collateral arteries and retrogradely in at least one of the left-sided arteries. We describe a 50-year-old male with atypical chest pain and positive treadmill exercise test who received coronary angiography and spiral 64-slice computed tomography; both studies showed atresia of the left main coronary artery and very thin proximal left anterior descending artery and left circumflex artery and tight coronary artery collateral to the left anterior descending anti left circumflex arteries. Spiral 64-slice computed tomography can provide a non-invasive diagnostic tool for complex congenital coronary anomalies and clear anatomic vision of coronary arteries. |
