IMPRoving Outcomes in Vascular DisEase - Aortic Dissection (IMPROVE-AD)

April 28, 2026 updated by: Duke University

IMPRoving Outcomes in Vascular DisEase- Aortic Dissection

The goal of this clinical trial is to determine whether an upfront invasive strategy of TEVAR plus medical therapy reduces the occurrence of a composite endpoint of all-cause death or major aortic complications compared to an upfront conservative strategy of medical therapy with surveillance for deterioration in patients with uncomplicated type B aortic dissection.

Study Overview

Detailed Description

The study will be a prospective, pragmatic, randomized clinical trial of the comparative effectiveness of an initial strategy for the treatment of uncomplicated type B aortic dissection (uTBAD). Patients with uTBAD and no prior history of aortic intervention will be randomized within 48 hours to 6 weeks after index admission to one of the two initial strategies. Follow-up will be ascertained via a centralized call center and ascertainment of medical records, as well as remote blood pressure monitoring. Recommendations regarding medical therapy will be made to enrolling centers and feedback on the quality of medical care given, however, all subsequent care, with the exception of aortic interventions, will be at the discretion of the responsible clinical care team. Aortic interventions will allowable only as per protocol.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Participants randomized to upfront TEVAR will receive a commercially available device customized to their individual anatomical requirements. Stent-graft implantation will be performed either in the operating room with appropriate digital imaging equipment to allow fluoroscopic and trans-esophageal echo (TEE) guidance or the catheterization laboratory, angiographic suite (with digital angiographic equipment).
Thoracic endovascular aortic repair
Routine clinical care with suggested antihypertensive therapy and cardiovascular risk factor reduction as per appropriate cardiovascular guidelines.
Active Comparator: Medical Therapy with surveillance for deterioration

Incidence of secondary percutaneous interventions after TEVAR
Time Frame: Last follow-up timepoint. Differential follow-up with median of about 4 years

Last follow-up timepoint. Differential follow-up with median of about 4 years
Quality of Life, as measured by the Abdominal Aortic Aneurysm Quality of Life questionnaire (AAAQol)
Time Frame: Last follow-up timepoint. Differential follow-up with median of about 4 years
An adapted version of the AAAQol survey and the PROMIS-16 will be used to assess general and aortic specific quality of life. The AAAQol questionnaire was specifically developed and validated on patients with abdominal aortic aneurysms and measures both the physical and emotional impact of either 1) having an abdominal aortic aneurysm or 2) having surgical or endovascular therapy for an abdominal aortic aneurysm. This metric has been shown to be valid and responsive in abdominal aortic aneurysm. While it has not been tested in aortic dissection, its questions assess the same domains shown to be significantly impacted in patients with aortic dissection.
Last follow-up timepoint. Differential follow-up with median of about 4 years
Incidence of all-cause death
Time Frame: Last follow-up timepoint. Differential follow-up with median of about 4 years
Death from any case
Last follow-up timepoint. Differential follow-up with median of about 4 years
Cumulative incidence of major aortic complications (MAC)
Time Frame: Last follow-up timepoint. Differential follow-up with median of about 4 years
Composite endpoint. MACs are defined as: • Aortic rupture • Malperfusion syndrome • New aortic tear requiring intervention, • Retrograde aortic dissection, • Dependence on outpatient dialysis (chronic) • Major amputation (above ankle) • Tracheostomy • fistula formation (e.g., aorto-esophageal, aorto-tracheal) • Spinal Cord Ischemia with paralysis or paresis • Stroke • AD-related intervention in either group defined as: - Open TAA/TAAA Repair - Fenestrated and/or Branched Endovascular Repair of TAAA - Repeat TEVAR
Last follow-up timepoint. Differential follow-up with median of about 4 years

Time Frame: Last follow-up timepoint. Differential follow-up with median of about 4 years
Defined as including: 1) flaccid paraplegia (no lower extremity movement), or lower extremity movement without gravity, or lower extremity movement with gravity, or standing with assistance or walking with assistance.
Last follow-up timepoint. Differential follow-up with median of about 4 years
Incidence of aortic-related death
Time Frame: Last follow-up timepoint. Differential follow-up with median of about 4 years
Aortic-related death will be defined as death within 30 days of 1) diagnosis of aortic dissection 2) any aortic intervention or 3) ruptured aortic aneurysm.
Last follow-up timepoint. Differential follow-up with median of about 4 years

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

The Statistical and data analytic center (SDCC) will submit to the NHLBI data repository de-identified Limited Access Datasets (LADs) and associated documentation, for use by other investigators. The LADs and documentation will be submitted within 2 years after publication of the primary results manuscript. Documentation will include copies of the case report forms; a list of derived variables and the formulas used to create them; and a codebook providing for each variable the variable name, coding conventions, and distribution of values. It will also include a list of data modifications made when creating the LAD, and a copy of the informed consent template, so that future use of the data will be consistent with the consent provided by the study subjects.The goal is to make data available to other investigators while protecting the rights and privacy of the subjects who participated in the studies. The SDCC will anonymize the datasets.

IPD Sharing Time Frame

2 years

IPD Sharing Access Criteria

The methods for restricting access will also need to be determined, either with password access and/or with executed Data Agreements. Related to the restricted use of data is the need to specify appropriately in informed consent forms that the study participant's de-identified data may be made available to other researchers.
