Overview

FSI modeling refinements may guide prosthetic valve research; leaves open clinical translation without prospective validation.

Structured PICO

P
Population
Prosthetic heart valves (bioprosthetic and mechanical) in computational models
I
Intervention
Fluid-structure interaction (FSI) simulations
O
Outcome
Hemodynamics and nonphysiologic flow patterns

Fluid-structure interaction simulations are crucial for understanding the nonphysiologic hemodynamics of prosthetic heart valves that contribute to clinical complications like thrombosis and structural damage.

Limitations

  • Lack of realistic, image-based ventricle and atrium geometries in current models
  • Lack of direct comparison between MHV and BHV under similar conditions
  • Need for better models to estimate platelet activation potential
  • Need to identify optimum placement of valves in mitral and aortic positions
