Aortic Regurgitation
For the entire cohort, the proportion of patients with moderate to
severe regurgitation significantly decreased between pre-and
post-operation (P<0.0001). In the pericardium group, 28 (93%)
had moderate to severe AR at baseline which improved to 11 (37%)
post-operatively and increased to 21 (70%) at time of follow-up. In the
biomaterial group, 8 (100%) had moderate to severe AR which improved to
3 (38%) post-operatively and increased to 7 (88%) at time of follow-up
(Table 2, Figure 2).
