Understanding the complex flow fields around artificial heart valves is essential to ensuring their safety and effectiveness. Turbulence, shear stresses, and recirculation zones can all impact hemocompatibility, durability, and long-term patient outcomes. That’s why Particle Image Velocimetry (PIV) testing has become a cornerstone of advanced valve evaluation.
At our laboratory, we perform PIV testing in full compliance with ISO 5840, the international standard governing heart valve prostheses. This cutting-edge optical technique provides detailed, quantitative insights into valve hydrodynamics under clinically relevant conditions.
- High-Resolution Flow Mapping:
Visualization of velocity fields, vortices, and shear layers around valve leaflets. - Quantitative Analysis:
Measurement of shear stress distribution, and flow uniformity. - Clinical Relevance:
Testing under pulsatile flow conditions replicating physiological pressures and cardiac cycles. - Regulatory Documentation:
Comprehensive reporting aligned with ISO 5840 requirements to support FDA, CE, and global approvals.
- Patient Safety:
Identifying regions of high shear stress or stagnation helps reduce risks of hemolysis and thrombosis. - Design Optimization:
Flow visualization guides improvements in leaflet geometry, hinge design, and material selection. - Accelerated Market Access:
ISO 5840 compliance streamlines regulatory pathways and builds confidence with clinicians and stakeholders.
By combining advanced optical instrumentation, expert analysis, and strict adherence to ISO standards, we help manufacturers validate the hydrodynamic performance of their artificial heart valves. Partnering with us means confidence in compliance, innovation, and patient protection.
