Baseline Characteristics for Tetralogy of Fallot Study, 43 Patients

A study of 43 patients with repaired Tetralogy of Fallot, comparing right ventricular assessment methods. The dataset contains baseline characteristics for patients who underwent same-day 2D echocardiography, 3D echocardiography, and cardiac magnetic resonance imaging between November 2023 and December 2024. The data was uploaded by Kwannapas Saengsin and last updated in March 2026.

Use Cases

• Validate echocardiography-derived volumetric parameters against cardiac magnetic resonance (CMR) as a reference standard.
• Analyze correlations between right ventricular ejection fraction (RVEF) and global longitudinal strain (GLS) across imaging modalities.
• Assess the diagnostic accuracy of 3D echocardiography for detecting right ventricular systolic dysfunction.
• Compare measurement agreement using statistical methods like Bland-Altman analysis mentioned in the study description.

Strengths

• Data is directly tied to a published study methodology with specific statistical results (e.g., correlation r=0.95 for RVEDV).
• Includes multi-modal imaging comparisons (2DE, 3DE, CMR) for the same patient cohort on the same day.
• File size is 5.5 KB, indicating a concise and likely well-structured dataset for the given scope.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (43 patients), limiting statistical power for broader generalization.
