Key result
Observational data informs mechanical versus bioprosthetic valve selection for AVR under 50.
Why the study?
The optimal type of aortic valve prosthesis for replacement in young patients under 50 years old remains controversial.
Key points are not available for this paper at this time.
Population
Young patients under 50 years old undergoing aortic valve replacement
Comparison
Biological prosthesis versus mechanical prosthesis
Design
Observational study
Observational data on valve choice for AVR in patients under 50 should not yet change practice; leaves open optimal selection pending randomized trials.
Schnittman and colleagues have recently published a very interesting observational study from the Mount Sinai group (1). It contributes with new and useful data on the controversial issue of the most adequate aortic valve type when performing an aortic valve replacement (AVR) in young patients (under 50 years old).

Alperi et al. (2018) studied this question. Aortic valve replacement in patients under 50 years old involves a controversial choice between biological and mechanical prostheses, which is being informed by new observational data.
