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).
