Inflow conduits at explant. Gross photography of longitudinally sectioned Cooley (A) and Vascutek (B) conduits, from a 17 year old supported for 61 days and an 18 year old supported for 99 days, respectively, both male with idiopathic cardiomyopathy and both successfully transplanted. Note the retracted, nonadherent pannus on the explanted Cooley conduit and the smooth adherent pannus lining the Vascutek conduit.

Freedom from embolic CVA. Freedom from embolic CVA was computed using the Kaplan-Meier algorithm. During the observation period (180 days post-LVAS implantation), the risk of embolic CVA was significantly lower in the test group (p = 0.022, log-rank statistic). The number of patients at risk (control, test) were 204, 139 at 1 month; 157, 106 at 2 months; 95, 79 at 4 months; and 64, 36 at 6 months.
