The MSCT manifestations of a left coronary artery-to-right atrium fistula before and after the transcatheter closure were reported. Before treatment, MSCT showed a dilated left coronary sinus and the dilated left main trunk, which coursed along the coronary sulcus to form the left circumflex artery, draining directly into the right atrium in the left middle part. The fistula was occluded with a PDA occluder. Four days after the occlusion, MSCT showed that the fistula was completely occluded and there was massive thrombosis in the central part and around the occluder. The thrombus was found even in the segment near to the start point of the oblique marginal artery.
报道了 1 例经导管封堵术前后左冠状动脉-右心房瘘的 MSCT 表现。治疗前 MSCT 显示左冠状窦及左主干扩张，沿冠状沟走行形成左回旋支，直接汇入右心房中部。瘘口用 PDA 封堵器封堵。封堵后 4d MSCT 显示瘘口完全闭塞，封堵器中央及周围见大量血栓形成，甚至在靠近斜角边缘支起始段的节段也发现血栓。
