Key result
Computational modeling demonstrated that thinner, more compliant biological tissues in aortic valve replacements induce significant leaflet flutter, initiating blood flow disturbances and oscillatory strains.
Why the study?
The impact of incorporating thinner, more flexible biological tissues in catheter-based bioprosthetic aortic valves within the dynamic valvular system remains poorly understood.

Thinner leaflets may raise flutter concerns in TAVR; leaves open durability questions pending clinical validation.
Do thinner biological tissues in bioprosthetic aortic valves induce leaflet flutter and flow disturbances in a computational model?
Computational modeling reveals that thinner biological tissues used in transcatheter aortic valves induce significant leaflet flutter, which may accelerate valve deterioration and cause blood damage.
Johnson et al. (2020) studied Valvular heart disease. Thinner, more compliant aortic valve tissues was evaluated on Leaflet flutter, blood flow disturbances, and oscillatory leaflet strains. Computational modeling demonstrated that thinner, more compliant biological tissues in aortic valve replacements induce significant leaflet flutter, initiating blood flow disturbances and oscillatory strains.
