Does first-step utilization of vein of Marshall ethanol infusion improve acute mitral isthmus block rate and reduce arrhythmia recurrence in patients with perimitral atrial tachycardia?
First-step utilization of vein of Marshall ethanol infusion for perimitral atrial tachycardia improves acute block rates and reduces arrhythmia recurrence while decreasing the need for radiofrequency ablation.
PMAT is the most common type of iatrogenic AT after AF ablation procedures. EIVOM contributed to a higher acute MI block rate and lower arrhythmia recurrence risk during follow-up. First-step utilization of EIVOM significantly reduced the need for radiofrequency ablation at MI and inside CS with the advantage of creating a homogenous, transmural lesion and eliminating epicardial connections.
