Data Sheet 1_Multi-chamber three-dimensional myocardial strain assessment by computed tomo

93 patients with severe aortic stenosis undergoing TAVI evaluation provided data for this study comparing strain measurements from cardiac CT and echocardiography. The dataset, authored by Vitaliy Androshchuk and last updated in May 2026, includes left ventricular, left atrial, and right ventricular global longitudinal strain values. It examines the agreement between imaging modalities and the association of strain with pulmonary hypertension.

Use Cases

• Compare agreement between CT-derived and echocardiography-derived strain measurements based on correlation coefficients (r-values) for LV-GLS, RV-GLS, and RV-FWLS.
• Identify optimal strain cutoff values for detecting high-probability pulmonary hypertension based on the reported CT and TTE thresholds.
• Assess the reproducibility of strain measurements based on the reported intraclass correlation coefficients (ICC > 0.9).
• Evaluate the prognostic value of multi-chamber strain for disease progression in aortic stenosis based on the study's association findings.

Strengths

• Includes data from 93 patients, with 43 classified as high-probability pulmonary hypertension and 50 as low-probability.
• Reports strong agreement (r > 0.78) between CT and TTE for most strain measurements.
• Strain measurements show excellent reproducibility with an intraclass correlation coefficient greater than 0.9.

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 a 4.2 MB DOCX file, suggesting it may be a document containing results rather than raw patient-level data.

Collection Method

Strain measurements were determined using 2D transthoracic echocardiography and CT-based 3D motion tracking in patients undergoing TAVI evaluation.
