Who could benefit from this research

Could help

Adults diagnosed with Type B aortic dissection being considered for TEVAR or related management.

Less likely to help

Patients without TBAD or those not undergoing TEVAR planning are unlikely to benefit.

What this research studies

This project uses 4D flow MRI to measure heart and blood flow dynamics in people with Type B aortic dissection to identify which patients are at higher risk of adverse outcomes after treatment. We will compare flow patterns, energic metrics, and blood movement between true and false lumens, and see how these relate to outcomes after TEVAR. The goal is to develop clearer imaging biomarkers that clinicians can use to tailor treatment timing and strategies. The study builds on prior findings that 4D flow MRI can quantify flow and hemodynamics in TBAD, and will address barriers like measurement accuracy and reproducibility to enable clinical use.

Why it matters

Potential benefit: If successful, patients with TBAD could receive more precise risk assessments and personalized treatment plans, potentially reducing complications and unnecessary procedures.

How similar studies have gone: Previous small studies suggest hemodynamic 4D flow markers relate to outcomes, but larger, validated data are needed.
