BACKGROUND The vein of Marshall (VOM) is a left atrial (LA) vein that contains autonomic innervation and triggers of AF. Its location coincides with areas usually ablated during pulmonary vein (PV) antral isolation (PVAI). OBJECTIVE This study sought to delineate the safety and ablative effects of ethanol infusion in the VOM during catheter ablation of(More)
BACKGROUND Treatment of perimitral flutter (PMF) requires bidirectional mitral isthmus (MI) block, which can be difficult with radiofrequency ablation (RFA). The vein of Marshall (VOM) is located within the MI. OBJECTIVE To test whether VOM ethanol infusion could help achieve MI block. METHODS Perimitral conduction was studied in patients undergoing(More)
UNLABELLED Vein of Marshall Ethanol in Recurrent AF. INTRODUCTION Atrial fibrillation (AF) or flutter can recur after pulmonary vein (PV) antral isolation (PVAI). The vein of Marshall (VOM) has been linked to the genesis of AF. We hypothesized that the VOM may play a role in AF recurrences and that VOM ethanol infusion may have therapeutic value in this(More)
