Aortic Dissection Clinical Trial
Official title:
Dissected Aorta Repair Through Stent Implantation (DARTS): A Feasibility Study
The objective of this study is to investigate the feasibility and clinical benefits of the AMDS to treat patients with acute DeBakey type I dissections and/or intramural hematomas (IMH) involving the ascending aorta and aortic arch through open surgical repair.
AMDS is designed to complement the replacement of the ascending aorta with conventional surgical technique utilizing a conventional polyester graft. AMDS is constructed of an uncovered Nitinol wire braided stent attached proximally to a polytetrafluoroethylene (PTFE) felt graft component. The PFTE felt graft component excludes the FL at the distal aortic anastomosis and the wire stent re-expands the dissection flap within the arch and descending aorta, which aims to treat malperfusion and promote positive remodeling of the aorta. The DARTS I Feasibility study is a prospective, non-randomized, non-blinded, single-arm, multi-institutional Canadian study evaluating the feasibility and safety of the AMDS graft. A goal of 40 subjects will be enrolled at approximately 5 sites in Canada. The enrollment period will span a minimum of 12 months from Institutional Review Board (IRB) approval and site activation. Candidates for this study are adults who require repair of an acute DeBakey type I aorta dissection and/or intramural hematoma (IMH). Patients will be consented pre-operatively and enrolled patients will be followed for approximately 5 years after their AMDS implantation date. Data will be collected at 10 time points: baseline (pre-operatively), discharge, 1 month post-operatively, 3 months post-operatively, and 6 months post-operatively, 1 year post-operatively and thereafter, annually, for a total of 5 years. ;
