New Stent Graft for Thoracic Aneurysms Offered at Penn
University of Pennsylvania Medical Center serves as regional site for national
trial
(Philadelphia, PA) – In an important step toward further establishing
treatment options for patients with life-threatening aneurysms or trauma involving
the aorta, the body’s largest artery, the University of Pennsylvania
Medical Center is participating in an FDA-approved clinical trial of
the Talent(TM) Thoracic Stent Graft System, manufactured by Medtronics, Inc.
Ronald M. Fairman, MD, Chief of Penn’s Division of Vascular
Surgery is the primary investigator for the nation-wide “VALOR”
trial, which is taking place at 35 sites across the country with Penn as the
only site in the Philadelphia region. Joseph E. Bavaria, MD,
Director of Penn’s Thoracic Aorta Surgery and Lung Transplantation Programs,
serves as co-investigator at the Penn site.
“This is an extremely important trial, as we will be exploring the safety
and effectiveness of a device that could significantly increase the number of
treatment options for thoracic aneurysm patients,” said Fairman. “In
most instances, treatment options are limited and, as a result, mortality rates
high. I’m hopeful that we can establish that this stent is both safe and
effective, ultimately providing patients with a new option that could save their
lives.”
The procedure involves introducing the stent graft through a small opening in
the femoral artery of the leg, and advancing it under fluoroscopic guidance
to the site of the thoracic aortic aneurysm or dissection, where it is then
deployed. Once placed, the stent graft expands to fit the diameter of the aorta,
thereby excluding the aneurysm by providing a new path for blood.
It is estimated that there are more than 21,000 patients diagnosed with thoracic
aortic aneurysms yearly in the U.S. A number of these patients also have serious
co-morbidities such as coronary artery disease, emphysema, high blood pressure
and diabetes that make it difficult – if not impossible – for them
to survive open surgical repair, which is the current standard of care. Open
surgery is a risky, taxing procedure that can lead to death in many frail and
elderly patients and can also be associated with severe complications, such
as paraplegia. For those patients considered ineligible for open surgical repair,
conservative medical management or “watchful waiting” is often used
as a treatment option and can lead to increased mortality and morbidity in many
elderly patients.
The TalentTM Thoracic Stent Graft System has been approved for over five years
in Europe and has been implanted more than 6,000 times worldwide. The VALOR
study is a prospective, non-randomized, multi-center, consecutive trial enrolling
patients in three separate study arms:
Patients will be divided into three categories: those diagnosed with thoracic
aortic aneurysms who are considered candidates for open surgical repair and
who are of low- to-moderate risk of major complications; those patients with
Type B thoracic aortic dissections, aneurysms associated with dissections, and
pseudoaneurysms; and high-risk/non-surgical candidates: including patients with
traumatic thoracic aortic aneurysms – incurred through emergencies such
as car accidents – who do not have a complete severing of the aorta.
“The standard operation for thoracic aortic aneurysms is difficult for
the patient, requires a lengthy recovery period, and can only be done when absolutely
necessary,” said Bavaria. “This new therapy is revolutionary and
allows much greater access to aneurysm repair in the chest with better outcomes.”
