Acute type A aortic dissection (ATAAD) is a life-threatening disease with high mortality. Surgery remains the gold standard for the treatment of ATAAD. In recent years, ATAAD is still a persistent challenge for cardiovascular surgeons. This is a retrospective study based on the data available in our hospital database for ATAAD patients undergoing total aortic arch replacement with elephant trunk stent under cryogenic stop circulation from January 2020 to December 2021. These patients were divided into three groups according to the surgical procedures of aortic root: continuous aortic root suture group (CARS group); intermittent mattress type built-in skirt forming method group, which was created by our group and to be named as XJ-procedure (XJ-procedure group, XJ is an acronym for Xi'an Jiaotong University); aortic root replacement group (Bentall group). The primary outcomes were 30-day mortality and incidence of recurrent dissection of aortic root (before discharge, 3 and 6 months of follow-up). The secondly outcomes were the rate of reoperation for aortic root bleeding, the incidence of pseudoaneurysms and the severe aortic valve regurgitation (the residual aortic valve regurgitation greater than grade2+) rate before discharge, 3 and 6 months of follow-up. Compare Baseline data, perioperative and short-term follow-up results between the three groups. To evaluate the efficacy and safety of XJ-procedure in ATAAD.
