Highlights a rare complication of inter-atrial septum dissection and pericardial effusion during Marshall-Plan atrial fibrillation ablation.
Abstract Catheter ablation has become an established treatment modality for atrial fibrillation (AF), particularly in patients with refractory or intolerant responses to medical therapy1. The Marshall-Plan has garnered interest in this field for its ability to achieve durable posterior mitral isthmus ablation2. 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 considered3,4. Here, we report a case of suspected inter-atrial septum (IAS) dissection during Marshall-Plan AF ablation, complicated by the development of a saline transudative pericardial effusion. The study adheres to the Declaration of Helsinki.
