Wall Shear Stress Vector Field Decomposition in Aortic Blood Flows

Comprising results from a Hodge decomposition analysis of wall shear stress vector fields in aortic blood flows. The analysis compares 11 patients with coarctation of the aorta before and after treatment against 10 control patients. The decomposition subdivides the vector field into five components: gradient, co-gradient, and three harmonic fields.

Use Cases

• Compare the five Hodge decomposition components (gradient, co-gradient, center, Neumann, Dirichlet fields) between CoA patients and healthy controls.
• Analyze the harmonic blood flow components to distinguish flow from the inlet from circulations induced by interior geometry topology.
• Investigate the significance of differences in decomposed WSS vector fields before and after treatment for coarctation of the aorta.

Strengths

• Analysis includes data from 21 total subjects (11 patients and 10 controls).
• Provides a comparative analysis of patients before and after treatment for coarctation of the aorta.
• Applies a novel discrete boundary-sensitive Hodge decomposition method to wall shear stress vector fields.

Limitations

• Specific sample size, row count, and column structure are unknown.
• Data is derived from a specific study of coarctation of the aorta, limiting generalizability to other cardiovascular conditions.
• The dataset's raw numerical data and file formats are not described.
