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 procedure. The ablation strategy consisted of liner ablations, including the roof, bottom, and mitral isthmus, as well as pulmonary vein isolation. Ethanol 5 mL was infused into the Marshall vein before pulmonary vein isolation while locating the Advisor HD grid mapping catheter (Abbott, St Paul, MN) and checking the real-time voltage map using the EnSite LiveView Dynamic Display (Abbott). First, the voltage colored area on the posterior side of the left inferior pulmonary vein was eliminated.
