Dual left anterior descending artery (LAD) is a rare coronary anomaly that is important to recognize at coronary imaging as it may influence reperfusion strategies. Four types of dual LAD are described by the traditional literature. We present a novel case of dual LAD with coronary computed tomographic angiographic correlation that does not fit into this classification system. Rather, our case supports the recently proposed notion of adding a fifth variant to the traditional dual LAD classification system.
双左前降支动脉（LAD）是一种罕见的冠状动脉异常，在冠状动脉成像中识别它很重要，因为它可能会影响再灌注策略。传统文献描述了四种双LAD类型。我们展示了一例双LAD的新病例，并伴有冠状动脉计算机断层血管造影相关性，该病例不符合此分类系统。相反，我们的病例支持最近提出的在传统双LAD分类系统中增加第五种变体的观点。
