Improving Outcomes in Aortic Dissection: Upfront TEVAR vs Surveillance (IMPROVE-AD) for Uncomplicated Type B Dissection

Official title: 1/2 IMPRoving Outcomes in Vascular DisEase - Aortic Dissection (IMPROVE-AD)

Funded at Duke University · NIH-11605967 · Data updated 2026-11-12

A large, patient-friendly study will compare starting with medicine plus an upfront TEVAR procedure versus medicine with careful monitoring for people with uncomplicated type B aortic dissection.

Who could benefit from this research

Could help

Adults with uncomplicated type B aortic dissection who meet trial eligibility.

Less likely to help

Patients with contraindications to TEVAR or who do not fit the study criteria may not benefit.

What this research studies

This project plans a pragmatic, multicenter trial in the United States enrolling about 1,100 participants to determine whether adding upfront TEVAR to standard medical therapy improves outcomes compared with ongoing medical therapy and monitoring in uncomplicated type B aortic dissection. Participants will undergo routine medical care with assessments for signs of deterioration, and clinically indicated TEVAR or open repair may be performed if needed. The trial is led by Duke, Baylor, and University of Washington teams with a dedicated data and clinical coordination center to ensure robust and real-world applicability. The aim is to establish clear guidance on how best to manage uTBAD to reduce death and complications.

Why it matters

Potential benefit: If successful, the trial could change standard care for uTBAD, potentially improving survival and reducing complications.

How similar studies have gone: This is one of the first large-scale trials to evaluate upfront TEVAR in uTBAD, with the potential for impactful results.
