Meta-Analysis of Intracardiac vs. Transesophageal Echocardiography for LAAO

Twenty clinical studies with 3,610 atrial fibrillation patients compare procedural outcomes for left atrial appendage occlusion. The meta-analysis synthesizes data from four databases up to December 2022, finding comparable efficacy and safety between two imaging guidance methods. Author Zhi-Yuan Zhang published the results under a CC-BY-4.0 license.

Use Cases

• Comparing procedural success rates between ICE and TEE guidance based on the reported risk ratios.
• Analyzing the impact of patient subgroups (e.g., hypertension, paroxysmal AF) on procedural metrics like contrast use.
• Benchmarking total procedure time and fluoroscopic time for LAAO procedures using different imaging modalities.

Strengths

• Aggregates data from 20 eligible studies, providing a synthesized view.
• Includes results for 3,610 patients (1,564 ICE, 2,046 TEE).
• Reports specific statistical metrics like risk ratios and weighted mean differences for key outcomes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 17.9 KB file size suggests the dataset is a summary document, not a raw clinical data repository.
