A 51-year-old patient with progressive right heart dysfunction was found to have a large calcified right atrial mass on echocardiography. As part of the work up for an intracardiac mass he had a cardiac computed tomogram which detailed a large coronary cameral fistula from the circumflex coronary artery to the right atrium associated with a spherical calcific pseudo-aneurysmal sac. Transcatheter occlusion of the exit point into the atrium with a vascular plug was performed directly from a right atrial approach without the need for an arteriovenous wire loop. This case details a unique presentation of a coronary cameral fistula to an unusual position within the right atrium which facilitated the rare ability to occlude the fistula from a venous approach without creating an arteriovenous wire rail.
一名 51 岁的患者因进行性右心功能障碍，在超声心动图检查中发现右心房有一个大的钙化右心房肿块。作为心内肿块检查的一部分，他进行了心脏计算机断层扫描，详细显示了一个从回旋支冠状动脉到右心房的大冠状窦房结瘘，并伴有球形钙化假性动脉瘤囊。通过从右心房直接进行血管塞的方法，在无需动静脉导丝环的情况下，经导管将出口点闭塞到心房内。该病例详细描述了一种独特的冠状动脉窦房结瘘的表现，该瘘位于右心房的异常位置，使得从静脉途径闭塞瘘的罕见能力得以实现，而无需建立动静脉导丝轨道。
