Overview

Potential variance in aortic silicone prostheses warrants monitoring; leaves open larger cohort validation of failure rates.

Structured PICO

P
Population
One specimen of a silicone elastomer heart ball valve
I
Intervention
Laboratory characterization of the polymer before and after implantation
O
Outcome
Polymer integrity and mechanism of ball variance

Analysis of a silicone heart valve specimen highlights the potential for functional variance as a failure mode, occurring in up to 1.5% of aortic prostheses.

Limitations

  • Evaluation of only one specimen
  • Results should not be taken to mean that every silicone ball will show this variance
