Major adverse events were defined as operative death, stroke, paraplegia, paraparesis, or renal failure requiring renal replacement therapy.

Emergency or urgent repair was performed in 14.6% of cases. Genetically triggered aortopathies were present in 16.5% of patients. In-hospital mortality occurred in 14.6%, with major adverse events in 23.3%. Stroke occurred in 4.6%, paraplegia in 2.9%, paraparesis in 5.2%, and permanent dialysis in 4.0%. Risk factors for operative mortality identified by univariable analysis included increasing age (OR, 1.074; 95% CI, 1.026-1.124) and previous myocardial infarction (MI) (OR, 5.920; 95% CI, 1.964-17.841). Factors associated with major adverse events included increasing age (OR, 1.053; 95% CI, 1.020-1.088), coronary artery disease (OR, 3.065; 95% CI, 1.274-7.376), previous MI (OR, 5.931; 95% CI, 2.012-17.488), and history of coronary artery bypass grafting (OR, 5.192; 95% CI, 1.161-23.223). Postoperative complications significantly associated with adverse outcomes included tracheostomy, ARDS, sepsis, and cardiac complications. The reintervention rate post-discharge was 15.8%. An overall 58.6% 5-year survival and 65.7% survival at 5 years following elective surgical repair were found.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
