The real-time visualization of left inferior pulmonary vein isolation by ethanol infusion into the Marshall vein

A 64-year-old man diagnosed with persistent atrial fibrillation underwent a first ablation process. The ablation strategy consisted of liner ablations, including the roof, bottom, and mitral isthmus, as well as pulmonary vein isolation. Ethanol infusion of 5 mL into the Marshall vein was performed prior to pulmonary vein isolation while locating the AdvisorTM HD grid-mapping catheter (Abbott, St Paul, Minnesota, USA) and checking the real-time voltage map using the EnSiteTM LiveView Dynamic Display (Abbott).
