Artificial heart valves must be evaluated not only through physical testing but also by advanced computational methods that provide deeper insights into blood flow behavior. Computational flow field assessment is a powerful tool for visualizing and quantifying velocity fields, shear stresses, and turbulence patterns around valve structures. These analyses are critical for understanding hemocompatibility, optimizing design, and ensuring compliance with international standards.

At our laboratory, we perform computational flow field assessments in full compliance with ISO 5840, the global benchmark for heart valve prostheses. This ensures every device is validated using both experimental and computational approaches.

Artificial heart valves must not only enable efficient forward blood flow but also prevent excessive leakage in the reverse direction. Steady backward leakage testing is a critical evaluation that measures regurgitant flow under controlled, non-pulsatile conditions. This ensures valves maintain proper closure and minimize risks of inefficiency, clot formation, or patient complications.

At our laboratory, we perform steady backward leakage testing in full compliance with ISO 5840, the international standard for heart valve prostheses. This rigorous assessment validates valve sealing performance and provides essential data for regulatory approval and design optimization.

Artificial heart valves operate under relentless mechanical and physiological stresses, opening and closing millions of times throughout a patient’s life. To ensure long-term reliability, manufacturers must evaluate how valves behave under dynamic loading conditions — identifying potential points of weakness before they reach the clinic. This is where dynamic failure mode testing becomes essential.

At our laboratory, we perform dynamic failure mode testing in full compliance with ISO 5840, the international standard governing heart valve prostheses. This rigorous evaluation simulates real-world operating conditions to uncover mechanical vulnerabilities and validate device durability.

Artificial heart valves must deliver consistent, unobstructed blood flow to sustain life. One key evaluations in valve development is steady forward flow testing, which measures how effectively a valve maintains forward flow under controlled, non-pulsatile conditions. This testing provides essential data on valve efficiency, pressure gradients, and effective orifice area — all key indicators of clinical performance.

At our laboratory, we perform steady forward flow testing in full compliance with ISO 5840, the international standard for heart valve prostheses. By adhering to this rigorous framework, we ensure every valve is validated against globally recognized benchmarks for safety and reliability.

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.

Artificial heart valves must deliver precise, reliable blood flow under the demanding conditions of the cardiovascular system. Their hydrodynamic performance — the ability to regulate forward flow while minimizing regurgitation and pressure gradients — is a critical determinant of both safety and long-term clinical success.

At our laboratory, we perform hydrodynamic performance testing in full compliance with ISO 5840, the international standard governing heart valve prostheses. This ensures every device is rigorously evaluated against globally recognized benchmarks.

Artificial heart valves must remain durable and biocompatible throughout years of continuous operation. One of the most critical long-term risks is calcification — the deposition of calcium salts on valve leaflets and supporting structures. Calcification can impair valve flexibility, increase regurgitation, and ultimately lead to device failure. Rigorous testing is therefore essential to validate valve durability and patient safety.

At our laboratory, we conduct calcification testing under internationally recognized protocols, providing manufacturers with the data needed to demonstrate reliability and compliance.

Artificial heart valves must withstand millions of cycles of opening and closing under pulsatile blood flow. Over time, mechanical fatigue, material degradation, and performance drift can compromise safety and reliability. That’s why accelerated wear testing (AWT) is a critical requirement in valve validation — ensuring devices deliver consistent performance throughout their intended lifespan.

At our laboratory, we conduct accelerated wear testing in full compliance with ISO 5840, the international standard for heart valve prostheses. This rigorous framework ensures every valve is evaluated under clinically relevant conditions, simulating years of operation in a condensed timeframe.
