Conclusions
This study provides an overview of contemporary published studies on
outcome after aortic root replacement with biological valve prostheses
and provides age-specific prediction of valve-related outcome. Patient
survival is impaired. Type of prosthesis is not associated with
(valve-related) outcome. Notably, thromboembolic events occur frequent,
especially during early follow-up.
This report may be used to benchmark the potential therapeutic benefit
of other surgical approaches.
