Congenital Left Circumflex Coronary Artery Artesia Detected by 64-Slice Computed Tomography: A Case Report
64切電腦斷層診斷左側冠狀動脈迥旋枝先天性閉鎖－病例報告
摘要
各種心臟的疾病，包括心肌內的冠狀動脈和冠狀動脈異常，均可能導致心因性猝死，尤其是在年輕人族群。在心因性猝死高危險群病人處理時，檢測心臟構造異常是非常重要的。冠狀動脈異常約佔百分之一的人口。先天性左側冠狀動脈迴旋枝缺乏是非常罕見的疾病，在先前的文獻中，實行冠狀動脈導管檢查病人中的發生率約為十萬分之三。雖然冠狀動脈導管檢查是偵測冠狀動脈疾病的標準診斷方法，但是電腦斷層是另一個可行的方式。我們報告一位17歲年輕女性病人，因運動時反覆胸痛及氣促於急診就醫，成功以64切電腦斷層診斷為左側冠狀動脈迴旋枝先天性閉鎖。此病人或許是第一個以64切電腦斷層診斷出為左側冠狀動脈迴旋枝先天性閉鎖的案例。
並列摘要
Avariety of coronary artery disorders, including intramyocardial coronary segments and coronary artery anomalies, can result in sudden cardiac death, especially in young adults. The detection of structural coronary artery abnormalities is important in the management of patients at risk of sudden cardiac death. Coronary artery anomalies occur in about 1% of the population. Congenital absence of left circumflex coronary artery (LCX) is a very rare vascular anomaly, and few cases have been reported in the literature, with a frequency of only 0.003% in all patients who underwent coronary angiography. Although coronary catheterization is the gold standard for the evaluation of coronary arterial patency disease, noninvasive computed tomography (CT) is considered the diagnostic method of choice for the detection and evaluation of coronary artery anomaly. Herein, we report the case of a 17-year-old girl who presented with exertional dyspnea and chest pain and who was studied at our emergency department with the final diagnosis of LCX atresia detected by 64-slice CT. She may be the first case of congenital LCX atresia proved by multislice CT.
