Thoracoscopic-assisted pulmonary vein isolation offers a feasible alternative for treating atrial fibrillation in patients whose prior percutaneous atrial septal defect closure devices preclude standard transseptal catheter ablation.
Atrial fibrillation (AF) is the main cause of morbidity among patients over 40 years of age with atrial septal defect (ASD). The closure of ASD in older patients does not decrease the occurrence of AF.(1-3) However, percutaneous ASD closure devices eliminate the possibility of a transseptal approach for future catheter-based procedures such as AF ablation. Epicardial pulmonary vein isolation with a bipolar radiofrequency clamp has been shown to be a safe and effective practice in surgical treatment of AF.(4,5) More recently, this technology has been utilized in a minimally invasive approach through bilateral thoracotomies. We present the case of a thoracoscopic-assisted pulmonary vein isolation on a patient with an atrial septal occlusion device.

Matsutani et al. (2008) conducted a case report in Atrial fibrillation with previous percutaneous atrial septal defect closure (n=1). Thoracoscopic-assisted pulmonary vein isolation was evaluated. Thoracoscopic-assisted pulmonary vein isolation was presented as a feasible approach for a patient with a pre-existing atrial septal occlusion device.
