Retrograde Ascending Dissection: Intraluminal Aortic Therapy

China149 participantsStarted 2026-01-01

Plain-language summary

This study is a single-arm, open-label, multi-center clinical trial evaluating the safety and efficacy of endovascular treatment for retrograde dissection involving the ascending aorta that is not suitable for open surgery. The aim is to assess the short-term (30 days) and medium- to long-term (6 months and 12 months) safety and efficacy of endovascular treatment in patients with retrograde dissection involving the ascending aorta who are not suitable for open surgery. The study plans to include patients with dissection confirmed by imaging, with the tear located in the aortic arch or descending aorta and extending retrogradely to the ascending aorta, and the most distal segment of the dissection is at least 2 cm away from the coronary artery ostia. These patients have been evaluated by cardiac surgery and found to be unsuitable for open surgery, with significant risks or risks outweighing benefits associated with open surgery. This is a single-arm, open-label, multi-center study, and no blinding or randomization will be used, nor will stratification factors be set. After successful screening, the subjects will undergo endovascular treatment for aortic dissection (stent implantation) during the operation. The subjects will be followed up for one year after the operation, and the safety and efficacy of endovascular treatment for retrograde dissection involving the ascending aorta will be evaluated based on the subjects' survival status, the occurrence of surgery and disease-related complications, and the recovery of the disease.

Inclusion Criteria: * Voluntary participation in the clinical trial; The individual fully understands and is informed of this study and has signed the informed consent form; Willing to follow and be able to complete all trial procedures * Age ≥ 65 years old, both male and female are eligible * Confirmed by imaging to be retrograde tear aortic dissection, that is, the tear site is located at the aortic arch or descending aorta, and the retrograde tear involves the ascending aorta. The farthest segment of the dissection tear is ≥ 2 cm from the coronary artery outlet * Evaluation by cardiac surgery indicates that open surgical treatment is not suitable, performing open surgery poses significant risks or the risks outweigh the benefits * Arterial access conditions are permitted, without severe stenosis or distortion, and the stent delivery system can be smoothly introduced; Exclusion Criteria: * Severe organ ischemia or functional failure, which, after assessment, is considered to have an extremely poor prognosis and cannot benefit from endovascular treatment, such as extensive cerebral infarction or cerebral hemorrhage, resulting in irreversible severe neurological deficits, acute extensive ischemic necrosis of the mesenteric arteries, acute liver and kidney failure; * Planned to undergo aortic valve repair/replacement or coronary artery interventional therapy within 30 days; * Mechanical heart valve present at the aortic valve position; * Aortic valve regurgitation degree ≥ …

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

The death events and major adverse cardiovascular and cerebrovascular events (MACCE) caused by any reason within 30 days after endovascular treatment, as well as their incidence rates
