To determine the prevalence and characteristics of dual left anterior descending artery (LAD) in adults undergoing catheter coronary angiography. We identified cases with dual LAD by retrospectively analyzing 3233 angiograms done from January 2017 to June 2019. Dual LAD was seen in 22 patients (0.68%). We identified type I dual LAD in 14 cases, type II in 7 cases and type III in 1 case. Significant stenosis was seen in proximal part of long LAD in 12 cases, in LAD proper in 7 cases and in proximal part of short LAD in 4 cases. Dual LAD is a rare anomaly. Its sound knowledge is essential for proper management of patients with coronary artery disease.
为确定接受导管冠状动脉造影的成年患者中双左前降支（LAD）的患病率及特征。我们通过回顾性分析2017年1月至2019年6月期间进行的3233例血管造影，识别出双LAD病例。22例患者（0.68%）可见双LAD。我们识别出14例I型双LAD、7例II型和1例III型。12例长LAD近端、7例LAD主干、4例短LAD近端可见明显狭窄。双LAD是一种罕见的异常情况。对其有充分了解对于冠心病患者的妥善管理至关重要。
