IMPRoving Outcomes in Vascular DisEase - Aortic Dissection

Not Applicable
Recruiting
Conditions
Type B Aortic Dissection
Registration Number
NCT06087029
Lead Sponsor
Duke University
Brief Summary

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.

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.

Primary Outcome Measures
NameTimeMethod
All-cause death or major aortic complications (MAC)Last follow-up timepoint. Differential follow-up with median of about 4 years

The primary endpoint is a composite of all-cause death or major aortic complications (MAC). 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

Secondary Outcome Measures
NameTimeMethod
Cumulative incidence of cardiovascular (CV) hospitalizationsLast follow-up timepoint. Differential follow-up with median of about 4 years

CV hospitalization will be defined as hospitalization \>/= 24 hours for any cardiovascular cause.

Mean number of cardiovascular (CV) hospitalizationsLast follow-up timepoint. Differential follow-up with median of about 4 years

CV hospitalization will be defined as hospitalization \>/= 24 hours for any cardiovascular cause.

Incidence of cardiovascular deathLast follow-up timepoint. Differential follow-up with median of about 4 years

Death from any cardiovascular cause.

Incidence of all-cause deathLast follow-up timepoint. Differential follow-up with median of about 4 years

Death from any case

Cumulative incidence of major aortic complications (MAC)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

Incidence of strokeLast follow-up timepoint. Differential follow-up with median of about 4 years

Defined as a focal neurological deficit that could be attributed to a vascular territory and lasted \>24 hours or was associated with a new lesion on computed tomography scan or magnetic resonance imaging.

Incidence of vascular access injury requiring surgical repairLast follow-up timepoint. Differential follow-up with median of about 4 years

Defined as any open surgical procedure to treat a vascular injury at the site of vascular access for a previous endovascular procedure.

Incidence of paraplegia or paraparesisLast 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.

Incidence of retrograde type A dissectionLast follow-up timepoint. Differential follow-up with median of about 4 years

Defined as any new ascending arch, or descending dissection contiguous with and proximal to the original presenting anatomy as confirmed by imaging.

Incidence of aortic-related deathLast 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.

Number of days alive and out of the hospitalLast follow-up timepoint. Differential follow-up with median of about 4 years

Defined as the number of days alive minus the number of days in the hospital over 4 years (primary analysis).

Quality of Life, as measured by the Abdominal Aortic Aneurysm Quality of Life questionnaire (AAAQol)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.

Incidence of aortobronchial / aortoesophageal fistulaLast follow-up timepoint. Differential follow-up with median of about 4 years

Defined as fistulous connection between the aorta and bronchus as confirmed by chest imaging or direct visualization (surgical or bronchoscopic). Aortoesophageal fistula is defined as a fistulous connection between the aorta and the esophagus as confirmed by chest imaging or direct visualization (surgical or endoscopically).

Incidence of secondary percutaneous interventions after TEVARLast follow-up timepoint. Differential follow-up with median of about 4 years

Any secondary percutaneous intervention after TEVAR
