|Medtronic Valiant(TM) Captivia(TM) Demonstrates Durability, Safety, and Efficacy at Five Years in Transection Patients|
New RESCUE Trial Data Presented in Blunt Thoracic Aortic Injury
DUBLIN and SAN DIEGO - January 30, 2019 - Medtronic plc (NYSE:MDT) today announced new data supporting the long-term durability, safety, and efficacy of the Valiant(TM) Captivia(TM) thoracic stent graft system for the treatment of blunt thoracic aortic injury (BTAI). The presentation by Himanshu J. Patel, M.D., University of Michigan Department of Cardiac Surgery at The Society of Thoracic Surgeons Annual Meeting, was the first and only five-year industry-issued dataset ever reported for patients with aortic transections undergoing thoracic endovascular aortic repair (TEVAR).
BTAI is an emergency medical condition in which the aorta is damaged due to traumatic force to the chest, usually the result of elevated falls or other high-impact injuries such as motor vehicle accidents. It is the second leading cause of traumatic death after head injuries. The data presented today by Dr. Patel came from the Evaluation of the Clinical PeRformancE of the Valiant Thoracic Stent Graft with the Captivia Delivery System for the EndovaSCUlar TrEatment of Blunt Thoracic Aortic Injuries (RESCUE) trial, a long-term study of this high-risk cohort of patients.
"These data from the RESCUE trial demonstrate that TEVAR with Valiant Captivia continues to be a valuable, safe, and less invasive alternative to open surgery for patients facing life-threatening aortic injury of BTAI, especially in the setting of critical multi-system injuries," said Dr. Patel. "This is the first five-year industry-issued dataset ever disseminated. The outcomes demonstrate Valiant Captivia to be a safe and durable therapy for high-risk BTAI patients."
The RESCUE study is a prospective, multi-center, non-randomized, descriptive study that evaluated a total of 50 patients with BTAI of the descending thoracic aorta. Subjects enrolled had a mean injury severity score (ISS) of 38.4 ± 14.4 and 70 percent (35/50) of BTAI extent was grade III or higher, including one grade IV free rupture, indicative of this extremely high-risk patient cohort. The extent of arch repair required full (40.0 percent, 20/50) or partial (18.0 percent. 9/50) left subclavian artery coverage. Of the 31 patients available at five years, 90.3 percent (28/31) received clinical follow-up, while 67.7 percent (21/31) received imaging follow-up.
Data highlights at five-year follow up:
"The Valiant Captivia five-year transection results demonstrate our commitment to life-saving treatments, and transparency in reporting long-term data to improve patient safety," said John Farquhar, vice president and general manager of the Aortic business, which is part of the Aortic, Peripheral, and Venous division at Medtronic. "These data also support our continuing focus on providing safe and durable endovascular repair to patients who have traditionally been challenging to treat."
