Supports Trifecta in small annuli; confirms similar exercise hemodynamics versus Freestyle in this RCT.
RCT (n=22)

Absolute Event Rate: 9.7% vs 7.4%
p-value: p=0.243
The Trifecta stented bioprosthesis provides excellent hemodynamic performance similar to the Freestyle stentless valve at rest and during exercise in patients with a small aortic annulus.
Tasca et al. (2015) conducted an RCT in Small aortic annulus (n=22). Trifecta bioprosthesis vs. Freestyle bioprosthesis was evaluated on Mean gradient at peak of exercise (p=0.243). The Trifecta stented bioprosthesis provided similar mean gradients at peak exercise compared to the stentless Freestyle valve (9.7 vs 7.4 mmHg; p=0.243) in patients with a small aortic annulus.
