Hemodynamic of the neo-aortic valve
There was a significant reduction in the medians of the peak (66mmHg, CI95%=52.5-81.3 vs 15mmHg, CI95%=12.1-17.5, p<0.0001) and mean (41mmHg CI95%=31.8-50.1 vs 8mmHg, CI95%=6.0-9.6, p<0.0001) AV gradients (Table 3, Figure 2A). In this period, no patient had a mean gradient greater than 20mmHg.
The sum of patients without AV insufficiency or with insufficiency grade I was 37/38 (97%), only one patient (3%) had AV regurgitation grade II, no cases with insufficiency grade III or IV were observed, when these data were compared with the preoperative period, the difference was significant (table 3).
