Data Sheet 1_Modified stepwise method with the guidance of QDOT MICRO catheter for mitral

A clinical trial document from figshare, authored by Jingchao Li, details a study comparing two catheter ablation methods for persistent atrial fibrillation. The dataset, last updated on 2026-03-18, includes results from 68 patients randomized into two groups, comparing operation times, ablation points, and block rates. It is shared under a CC-BY-4.0 license.

Use Cases

• Comparing procedural efficiency between catheter types based on operation and ablation times mentioned in the results.
• Analyzing the success rate of mitral isthmus block based on the reported block percentages for different ablation methods.
• Studying the impact of a modified stepwise ablation approach on reducing the need for epicardial ablation as described in the conclusions.

Strengths

• Includes specific statistical results (p-values) for comparisons between two patient groups.
• References a registered clinical trial (NCT06145906) for provenance.
• Document is 1.1 MB in size, indicating a detailed textual description of the study.

Limitations

• The dataset is a single DOCX file; the underlying structured data (e.g., patient-level records) is not directly accessible.
• Row count and column definitions are unknown, limiting suitability assessment for quantitative analysis.
• Description metadata is limited; actual data quality requires manual inspection after download.
