A 45-year-old woman with drug-refractory paroxysmal atrial fibrillation (AF) underwent AF ablation. She had a history of abnormal chest radiograph, which on review was consistent with congenital absence of pericardium and this was later confirmed on cardiac magnetic resonance imaging. She had extreme leftward and posterior rotation of the heart, resulting in abnormal fluoroscopic appearance of the electrophysiological catheters and orientation of the interatrial septum. This along with exaggerated beat to beat motion of the heart posed significant technical challenges for the electrophysiologist during left atrial access and pulmonary vein isolation.
一名45岁患有药物难治性阵发性心房颤动（房颤）的女性接受了房颤消融术。她有胸部X线片异常的病史，复查时发现与先天性心包缺如相符，后来心脏磁共振成像证实了这一点。她的心脏极度向左后方旋转，导致电生理导管在荧光镜下的外观异常以及房间隔的方向异常。这与心脏逐搏运动的过度增强一起，在左心房穿刺和肺静脉隔离过程中给电生理学家带来了重大的技术挑战。
