About this trial

HEADSTART is a prospective, open-label, non-blinded, multicenter, randomized controlled trial that compares a composite of mortality and re-intervention in patients undergoing hemiarch and extended arch repair for acute DeBakey type 1 aortic dissection. Eligible patients will be randomized to one or the other surgical strategy and clinical and imaging outcome data will be collected over a 3 year follow up period.
