Abe and associates reported the trends in the early outcomes of surgical repair for acute type A aortic dissection in 11,843 patients from the Japan Cardiovascular Surgery Database between 2008 and 2015. Operative mortality was 9.5% and 30-day mortality was 7.6%. The number of surgically treated cases increased by 45% during the interval. A signficant upward trend was found in patient age and the incidences of preoperative renal failure. Unadjusted operative mortality rate with arch replacement showed a significant downward trend (P = 0.01). Risk-adjusted mortality rate showed a downward trend both in ascending aortic or hemiarch and arch replacement, which did not reach statistical signficance.
