Is this trial a fit for you?

Likely a good fit

Ideal candidates include high-risk surgical patients with specific aortic pathologies affecting the ascending thoracic aorta who meet the inclusion criteria.

Probably not a fit

Patients who are pregnant, pediatric, or have conditions that could lead to infection of the stent graft will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the outcomes of patients with various pathologies of the ascending thoracic aorta, including type A aortic dissection and pseudoaneurysms, who are suitable for endovascular repair using the Medtronic Valiant PS-IDE Stent Graft. A total of 20 patients will be enrolled and followed for five years post-surgery. Participants will undergo a series of imaging tests, including CT scans and echocardiograms, to monitor their condition and the effectiveness of the stent graft over time.

Why it matters

Potential benefit: If successful, this approach could provide a less invasive treatment option for patients with serious aortic conditions, potentially improving survival rates and quality of life.

How similar studies have gone: Other studies have shown promise with endovascular approaches for aortic conditions, suggesting potential for success in this novel application.

Inclusion Criteria:

* Patient must have a Type A thoracic aortic dissection, retrograde Type A thoracic aortic dissection, intramural hematoma, penetrating ulcer or pseudoaneurysm of the ascending thoracic aorta affecting the area between the Sinus of Valsalva and the innominate artery orifice (with no involvement of the aortic valve) and be considered candidates for endovascular repair;
* Patient must also have at least one cm proximal and distal landing zones in the ascending aorta between 28-44 mm in diameter;
* The patient must be deemed high-risk surgical candidate according to the following established criteria: ASA (American Society of Anesthesiologists) class IV.

Exclusion Criteria:

* Pregnant or pediatric patients (younger than 21 years of age);
* Patients who have a condition that threatens to infect the stent graft/aortic valve prosthesis;
* Patients with allergies to the stent graft material;
* Patients or their legally authorized representatives who do not sign the informed consent;
* Patients with expected survival less than one year.
