TAVR Valves: The effect of Post Implantation leaflet Distortion on Durability

Bioprosthetic Heart Valves

Stent-Mounted Valves

High-Risk Surgery to Implant

 

The Goal

Assessment of the durability of the distorted TAVR based on stresses in the leaflets

 

Stent distortions changed the values and contours of stresses

Results demonstrated the effects of prosthesis-host mismatch on stresses in the leaflets

The chances of early deterioration is higher when the prosthesis experiences distortions

Surgical techniques that aim to minimize stent distortions help for improved valve durability

Further analysis is required to model stent distortions more realistically
