Patients and Operative Data
During the observational period of the study, 115 consecutive patients
underwent Perceval-S valve implantation in our institution and 103 were
included in the present study. The 12 excluded patients (10%) were
emergency situations (n = 5, including four patients with endocarditis)
and combined surgery other than AVR plus CABG (n = 7, including three
AVR plus mitral, two AVR plus tricuspid and three AVR plus mitral and
tricuspid procedures). Preoperative data are reported in Table 1.
Fifty-seven patients (55%) underwent isolated AVR, of which 17 (30%)
were performed via ministernotomy. The other 46 patients (45%)
underwent combined surgery with CABG (mean anastomoses 1.9). Mean CPB
times were 59.3 ± 45.4 min and 89.2 ± 43.5 min, and aortic cross-clamp
times were 39.4 ± 24.2 min and 69.0 ± 35.6 min in isolated AVR and
combined procedures, respectively.
