Short- and long-term outcomes of aortic root repair and replacement in patients undergoing acute type A aortic dissection repair: Twenty-year experience.

ABSTRACT: OBJECTIVE:The study objective was to evaluate the perioperative and long-term outcomes of aortic root repair and aortic root replacement and provide evidence for root management in acute type A aortic dissection. METHODS:From 1996 to 2017, 491 patients underwent aortic root repair (n = 307) or aortic root replacement (n = 184) (62% bioprosthesis) for acute type A aortic dissection. Indications for aortic root replacement were intimal tear at the aortic root, root measuring 4.5 cm or more, connective tissue disease, or unrepairable aortic valvulopathy. Primary outcomes were in-hospital mortality, long-term survival, and reoperation rate for root pathology. RESULTS:Patients' median age was 61 years and 56 years in the aortic root repair group and aortic root replacement group, respectively.
