Efficacy and safety of ethanol infusion into the vein of Marshall for mitral isthmus ablation

Abstract: Introduction Chemical ablation by retrograde infusion of ethanol into the vein of Marshall (VOM‐EI) can facilitate the achievement of mitral isthmus block. This study sought to describe the efficacy and safety of this technique. Methods and Results Twenty‐two consecutive patients (14 males, median age 71 years) with attempted VOM‐EI for mitral isthmus ablation were included in the study. VOM‐EI was successfully performed with a median of 4 ml of 96% ethanol in 19 patients (86%) and the mitral isthmus was succe… Show more

“…It was well-known that the ethanol dose was found to correlated with LVA size (10), which was consistent with the finding in our study. However, the correlation of ethanol dose with the success of MIth block had not been reported to the best of our knowledge.…”

“…The PentaRay catheter roved slowly in the LA to reconstruct the LA geometry as well as acquire 200-3,000 points evenly distributed at every aspect of the LA. Low voltage area (LVA) was defined as local bipolar peak-topeak potential ≤0.3 mV during sustaining AF or ≤0.5 mV in NSR (Figures 1C,D) (10,16), and was displayed as a red zone on LA geometry. The LVA contour was drawn manually and the LVA size was calculated by the built-in software tool of CARTO 3 system (Biosense Webster, USA).…”

“…Different strategies have been adopted to overcome the limitations of RF energy. The most successful strategy may be ethanol injection into the vein of Marshal for mitral isthmus line ablation, or adjunctive epicardial ablation for roof lines (4)(5)(6)(7). However, these adjunctive approaches are time-consuming and limited to experienced centers.…”
