Clinical impact of a new bioprosthetic aortic valve: the St. Jude Medical Trifecta™.

Background: The St. Jude Medical (SJM) Trifecta™ aortic valve was designed to face common issues such as high transvalvular pressure gradients and low effective orifice areas (EOAs), which lead to prosthesis-patient mismatch after implanting small valve sizes. To reduce the obstruction of the left ventricular outflow tract, the Trifecta™ was designed as a stented valve for supraannular placement.
