Inter-atrial septum dissection during atrial fibrillation ablation via atrial septal defect: A rare complication

Le résumé fourni par la source

Catheter ablation has become an established treatment modality for atrial fibrillation, particularly in patients with refractory or intolerant responses to medical therapy. The Marshall-Plan has garnered interest in this field for its ability to achieve durable posterior mitral isthmus ablation. This anatomically-based approach combines alcohol ablation of the vein of Marshall with pulmonary vein isolation, mitral roof, and isthmus ablation, and a cavotricuspid isthmus line. Despite its effectiveness, procedural complications, although rare, must be considered. Here, we report a case of suspected inter-atrial septum dissection during Marshall-Plan atrial fibrillation ablation, complicated by the development of a saline transudative peri-cardial effusion. The study adheres to the Declaration of Helsinki.
