SCAP Technique
In total, 34 patients (33%) required SCAP (Group SCAP); the other 69 patients (67%) benefited from a classical implantation technique (Group No-SCAP). In Group SCAP, only one SCAP was performed in 23 patients (68%) and a double SCAP in 11 patients (32%). Perceval-S sizes and SCAP techniques are reported in Table 2.
Moreover, the rate of SCAP’s use differed according to the anatomy of the aortic valve, as SCAP was necessary in 24 patients (28%) with a tricuspid aortic valve, versus in 10 patients (63%) among those who had BAV (figure 2).
For patients who underwent in isolated AVR procedure, mean CPB times were 57.0 ± 38.3 min and 64.6 ± 59.9 min, and aortic cross-clamp times were 39.7 ± 26.4 min and 38.7 ± 18.7 min in groups No-SCAP and SCAP, respectively (p = 0.57 and p = 0.90). This shows that SCAP did not significantly increase valve implantation or overall procedure times.
