Intentionally designed for durability and performance, Avalus™ bioprosthesis is our most advanced and effective surgical aortic tissue valve engineered for lifetime patient management.
Consistent mean pressure gradients out to 5 years.
Circularity is crucial, but not all aortic valves are circular. Noncircular or deformed surgical valves can have decreased durability and poor blood flow.5-8 The non-deformable polymer base of Avalus surgical aortic valve is designed to:
