Freedom from Re-Operation
At five years after AVR, freedom from reoperation was significantly
poorer in patients receiving CorMatrix (12.5%) compared to patients
receiving autologous pericardium (62.5%) (P = 0.01) (Figure 1).
16 patients (42%) underwent a re-operation of the aortic valve, with 10
patients requiring re-operation due to severe or recurrent AR and 6
patients with severe, critical, or worsening AS. 6 patients underwent
the Ross procedure, 2 underwent AVr with autologous pericardium, 5
underwent AVr with the Carpentier Edwards Valve, and 3 underwent AVr
with the Resilia Bovine Pericardial Valve. The mean length between the
initial operation and re-operation was 1390 days.
