Long-Term Efficacy of Vein of Marshall Ethanol Infusion for Persistent Atrial Fibrillation

A 2026 clinical study by Wei-Li Ge compares long-term arrhythmia-free survival rates between two treatment groups for persistent atrial fibrillation. The dataset likely contains patient outcomes over 36 months, including recurrence rates at 12, 24, and 36 months post-procedure. It was published on figshare under a CC-BY-4.0 license.

Use Cases

• Compare long-term treatment efficacy based on reported 12, 24, and 36-month recurrence rates.
• Analyze predictors of successful sinus rhythm maintenance based on the identified independent variables.
• Evaluate the clinical benefit of adjunctive ethanol infusion therapy mentioned in the study results.

Strengths

• Provides specific recurrence rates at three time points: 87.32% at 12 months, 80.25% at 24 months, and 77.46% at 36 months for the combined therapy group.
• Includes results from a comparative study with two defined patient cohorts (n=71 and n=41).
• Identifies independent predictors of long-term success through multivariate analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 149.9 KB, indicating limited scope.
