A calcified polymeric valve for valve-in-valve applications [PDF]
Journal of Biomechanics, 2017 The prevalence of aortic valve stenosis (AS) is increasing in the aging society. More recently, novel treatments and devices for AS, especially transcatheter aortic valve replacement (TAVR) have significantly changed the therapeutic approach to this disease.

A Mathematical Model of a Valve-Controlled Bioreactor for Platelet Production
Frontiers in Mechanical Engineering, 2022 As blood donor numbers decrease, while demand for platelets increases, hospitals worldwide are becoming increasingly vulnerable to critical platelet shortages. Alternative methods of supplying platelets are therefore required. One approach is to engineer

JACC: Case Reports, 2019 A female patient presented with severe, symptomatic aortic stenosis after distant surgical aortic valve replacement and subsequent transcatheter aortic valve implantation 6 years prior. A 23-mm CoreValve Evolut (Medtronic, Dublin, Ireland) was implanted with excellent symptomatic and hemodynamic results. (Level of Difficulty: Advanced.).
