AAS, acute aortic syndrome.

Complicated AAS: patients with AAS who developed any of the following complications before the surgical intervention: poor perfusion, kidney failure, myocardial infarction, tamponade, shock, and neurological complications.

a

The percentages of this variable are calculated with regard to the group of patients who underwent surgery (27 patients in the Aorta Code group and 14 patients in the Care-as-usual group).

b

The percentages of this variable are calculated with regard to patients with type A AAS (31 patients in the Aorta Code group and 14 patients in the Care-as-usual group).

c

The percentages of this variable are calculated with regard to the group of patients with type A AAS who underwent surgery (27 patients in the Aorta Code group and 13 patients in the Care-as-usual group).

d

The percentages of this variable are calculated with regard to the group of patients with type 1 AAS (involvement of the ascending and descending aorta) who underwent surgery (18 patients in the Aorta Code group and 10 patients in the Care-as-usual group).

In addition, and in line with the corrections, the text in the following paragraph: “Sixty percent of patients with type A AAS [acute aortic syndrome] were treated with the Bentall-De Bono procedure during the care-as-usual period. This percentage fell to 42% after implementation of the project, as 58% were treated with aortic root repair surgery. There was also a relative increase of 80% in the number of complete aortic arch procedures performed (P=.09) (table 2).” should be replaced by: “Of the patients requiring aortic root surgery, 60% (3 of 5 patients) were treated with the Bentall-De Bono procedure during the care-as-usual period. This percentage fell to 38.1% (8 of 21 patients) after implementation of the project, due to increases in aortic root repair surgery (9 of 21 patients, 42.9%) and the David procedure (4 of 21 patients, 19%). There was also a relative increase of 94.5% in the number of complete aortic arch procedures performed for type 1 AAS (77.8% [14] after implementation of the Aorta Code project vs 40% [4] in the care-as-usual period, P=.0045) (table 2).”
