Difficulties initiating sleep, difficulties maintaining sleep, and non-restorative sleep in octogenarian patients after SAVR or TAVI at baseline and on the first five postoperative nights.

Estimated mean scores, with 95% CIs, based on a longitudinal model. The number of patients varied between the different nights and the three questions. At baseline: TAVI 64–65, SAVR 78; 1st PO night: TAVI 56, SAVR 46–48; 2nd PO night: TAVI 52, SAVR 63; 3rd PO night: TAVI 51, SAVR 68; 4th PO night: TAVI 56, SAVR 65–66; 5th PO night: TAVI 54, SAVR 65–66.

CI: confidence interval; PO: postoperative; SAVR: surgical aortic valve replacement; TAVI: transcatheter aortic valve implantation.
