Reisolation of the left superior pulmonary vein by radiofrequency application in the left atrial appendage successfully eliminated the occurrence of recurrent atrial fibrillation.
Case Report (n=1)
Epicardial reconnection via the Marshall ligament region can be an unusual cause of recurrent atrial fibrillation after pulmonary vein isolation, treatable by radiofrequency application in the left atrial appendage.
The case of a 65-year-old man with recurrent atrial fibrillation after undergoing segmental pulmonary vein isolation caused by the reconnection of previously isolated pulmonary veins is herein reported. Interestingly, frequent ectopic firings in the left superior pulmonary vein conducted to the left atrium, not through its ostium but through the supposed epicardial pathway at the region of the Marshall ligament, which had been absent during the first treatment session. The reisolation of the left superior pulmonary vein by radiofrequency application in the left atrial appendage thus successfully eliminated the occurrence of atrial fibrillation.
Matsuo et al. (Tue,) conducted a case report in Recurrent atrial fibrillation (n=1). Reisolation of the left superior pulmonary vein by radiofrequency application in the left atrial appendage was evaluated on Occurrence of atrial fibrillation. Reisolation of the left superior pulmonary vein by radiofrequency application in the left atrial appendage successfully eliminated the occurrence of recurrent atrial fibrillation.
