Double-balloon technique for retrograde venous ethanol ablation of ventricular arrhythmias in the absence of suitable intramural veins

Popis výsledku v původním jazyce

Background: Venous ethanol infusion via an occlusive balloon has been used as a bailout approach to treat ablation-refractory ventricular arrhythmias (VAs). Unfavorable venous anatomy (lack of intramural veins at the targeted site or collateral vein–ethanol shunting) limits its efficacy. Blocking collateral flow with a second balloon may optimize myocardial ethanol delivery. Objective: The purpose of this study was to validate the “double-balloon” approach to enhance ethanol delivery in cases of unfavorable venous anatomy. Methods: Eight patients referred after failed ablations (3 left ventricular [LV] summit, 5 scar-related ventricular tachycardia) underwent endocardial mapping and additional radiofrequency ablation without VA resolution. Coronary veins were mapped using a multipolar catheter or wire, and selective venograms were obtained. The double balloon was used when (1) distal collateral branches shunted flow away from the targeted region; (2) the target vein had optimal signals only proximally; or (3) a large vein was targeted that had multiple branches for a large area of interest. Results: Acute successful ethanol infusion myocardial delivery and resolution of VA was accomplished using the posterolateral LV veins (n = 2 patients, 3 procedures), lateral LV vein (n = 1), apical anterior interventricular vein (AIV; n = 1), middle cardiac vein (n = 1), and septal branches of the AIV (n = 3). At median follow-up of 313.5 days, 2 patients experienced recurrence. Conclusion: The double-balloon technique can enhance ethanol delivery to target isolated vein segments, block collateral flow, or target extensive areas, and can expand the utility of venous ethanol for treatment of VAs. © 2020 Heart Rhythm Society
