Propensity matched long-term analysis of mechanical versus stentless aortic valve replacement in the younger patient.

Objectives: The choice of prosthesis for aortic valve replacement (AVR) in younger patients remains controversial. Stentless AVR was introduced 3 decades ago, with the aim of better haemodynamics and durability than stented xenografts. The objective of this analysis was to compare the long-term outcomes to mechanical prostheses in younger patients (age ≤60 years).

The St. Jude Toronto stentless bioprosthesis: up to 20 years follow-up in younger patients.

Background: A retrospective long-term evaluation of the St. Jude Toronto stentless bioprosthesis in patients aged 60 years or younger.

Methods: From 1994 to 1997, 50 patients underwent aortic valve replacement with the prosthesis.
