Clinical Trials

PMEG: Physician Modified Endovascular Grafts

  • PI: Benjamin Starnes
  • Description: A minimally invasive operation to repair juxtarenal aortic aneurysms that is proven safe and effective for patients unsuitable for open surgical repair. Due to the unique nature of the procedure, Dr. Starnes had to obtain an Investigational Device Exemption (IDE) from the FDA to be able to do these procedures and track subsequent outcomes. This was the first IDE of its kind in the United States and Dr. Starnes has enrolled over 200 patients in the trial to date.

Description: This clinical trial is a prospective, multicenter, non-blinded, non-randomized study designed to assess the RelayPro thoracic endografts in the treatment of acute, complicated type B aortic dissection. The primary endpoint will measure all-cause mortality at 30 days post-procedure.

ViTAA

  • PI: Benjamin Starnes
  • Description: This is a Prospective Registry study to collect imaging and clinical data both on patients with aortic aneurysm disease undergoing serial monitoring and on patients pre and post-endovascular repair, using ViTAA (The Sponsor) aortic mapping technology.

ELEGANCE: Drug-Eluting REGistry: Real-World Treatment of Lesions in the Peripheral Vasculature

  • PI: Elina Quiroga
  • Description: The ELEGANCE Registry's objective is to collect Real-World Data (RWD), including populations previously not represented in Peripheral Vascular Disease (PVD) trials, health economics data, and to support the safe use of commercially available Boston Scientific Corporation (BSC) drug-eluting devices for the treatment of lesions located in the peripheral vasculature.

BTEVAR: Branched Thoracic Endovascular Grafts for the Treatment of Thoraco-abdominal Aortic Aneurysms

  • PI: Matthew Sweet
  • Description: An investigator-initiated, prospective, consecutively enrolling, non-randomized single institution clinical evaluation of the safety and effectiveness of branched and fenestrated-branched endovascular stent grafts to preserve branch vessels when used in the treatment of patients with thoraco-abdominal aortic aneurysms. The study evaluates non-FDA-approved off the shelf and custom made branched and fenestrated-branched stent grafts manufactured by Cook Medical.

GORE TBE: Thoracic Branch Endoprosthesis

  • PI: Matthew Sweet
  • Description: The objective of this study is to determine whether the GORE® TAG® Thoracic Branch Endoprosthesis is safe and effective in treating lesions of the aortic arch and descending thoracic aorta, requiring Zone 2 proximal implantation of the device.

Multi-disciplinary Thoracic Aortic Program

Diseases of the thoracic aorta are life-changing diagnoses. The management of these conditions is complex and it is normal for patients and their families to feel overwhelmed by the prospect of major surgery as well as to worry about the long-term implications of this disease. We are here to help.

At the University of Washington “MTAP,” we believe that complex thoracic aortic disease is best treated by a team-based approach. We understand that no individual provider can tackle these complex issues alone, but rather acknowledge the benefit of a multi-disciplinary approach utilizing the diverse specialists available at the University of Washington. Our team includes both cardiac and vascular surgeons, along with collaborators in cardiology and medical genetics.
