The variants of the left anterior descending (LAD) coronary artery are important in interpretation of coronary angiogram and in interventional procedures. The double LAD coronary artery originating from the left main coronary stem and the right coronary artery is a rare congenital coronary anomaly. In this case report, we are describing a patient with the double left anterior descending coronary artery (type IV), one with normal origin, and the other originating from the right coronary artery. Anatomical knowledge of this rare variant of LAD is important for novice interventional cardiologists during interpretation of coronary angiogram. To the best of our knowledge, there are ∼28 cases of dual LAD (including type IV) reported in the literature.
左前降支（LAD）冠状动脉的变异在冠状动脉造影解读及介入操作中具有重要意义。起源于左冠状动脉主干和右冠状动脉的双左前降支冠状动脉是一种罕见的先天性冠状动脉异常。在本病例报告中，我们描述了一名患有双左前降支冠状动脉（IV型）的患者，其中一支起源正常，另一支起源于右冠状动脉。对于初涉介入心脏病学领域的医生而言，了解这种LAD罕见变异的解剖学知识，在解读冠状动脉造影时很重要。据我们所知，文献中报道的双左前降支（包括IV型）病例约有28例。
