Figure 2. Forest plot showing the study outcomes (A) Late AF/AT recurrence, (B) Acute mitral isthmus bidirectional block, and (C) procedural complications. Results showed that VOM-EI group was associated with a lower risk of late AF/AT recurrence and increased probability to achieve acute MIBB without an increase in procedural complications. Abbreviation: AF: Atrial fibrillation, AT: Atrial tachycardia, CA: catheter ablation, CI: confidence interval, VOM-EI: vein of Marshall ethanol infusion.
