Aortic Stenosis
For the entire cohort (N=40), the peak trans-valvular gradient
significantly decreased between pre-operative and post-operative
assessments (P =0.0017), with no significant change observed at
outpatient follow-up (P=0.36). In the pericardium group, the peak
trans-valvular gradient also significantly decreased pre- and
post-operatively (P= 0.012), with no significant change at outpatient
follow-up (P=0.12). In the CorMatrix group, only 4 patients had AS at
baseline; therefore, there was insufficient data for between-group tests
(Table 2).
