Hemiarch vs Extended Arch in Type 1 Aortic Dissection (HEADSTART)
Hemiarch vs Extended Arch in Aortic Dissection - a SystemaTic Analysis by Randomized Trial (HEADSTART)

Detailed Description
DeBakey Type 1 aortic dissections continue to have high operative mortality and morbidity and there is equipoise in available literature with regards to the best operative strategy and patient selection criteria. Hemiarch repair is current standard of care in most centers but extended arch repair is gaining popularity aiming to address early post-operative malperfusion and improve long term aortic remodeling.
HEADSTART is a randomized controlled prospective trial of patients presenting to participating institutes with acute DeBakey 1 aortic dissection. Patients will be enrolled and randomized into one of two groups - 'hemiarch repair' and 'extended arch repair'. Pre-operative, early post-operative and long term follow clinical and CT imaging data will be collated on a centralized database and at a core lab respectively.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: Hemiarch repair
Standard hemiarch repair with open distal anastomosis in the proximal arch without replacement of the head vessels.
|
Current standard of surgical repair consisting of ascending aortic replacement with open distal anastomosis at level of proximal arch under a period of hypothermic circulatory arrest .
No surgical or endovascular intervention is carried out in the mid arch or descending aorta.
Intra-operative management, including cannulation, cardioplegia, cerebral perfusion technique, and neurologic monitoring will be done according to each institution's current standard of practice.
|
ACTIVE_COMPARATOR: Extended arch repair
Ascending aortic and arch replacement with or without head vessel re-implantation and single TEVAR device placement within 1 week.
|
Surgical replacement of the ascending aorta along with intervention on the arch and descending aorta.
Techniques for distal aspect of extended arch technique include but are not limited to total arch replacement along with TEVAR, Frozen Elephant Trunk procedure or surgical proximal arch replacement with bare metal stents in arch and descending aorta.
Intra-operative management, including cannulation, cardioplegia, cerebral perfusion technique, and neurologic monitoring will be done according to each institution's current standard of practice.
