Numerical simulation of a transcatheter aortic heart valve under application-related loading
Current Directions in Biomedical Engineering, 2018 For the treatment of severe symptomatic aortic valve stenosis, minimally invasive heart valve prostheses have more recently become the lifesaving solution for elderly patients with high operational risk and thus, are often implanted in patients with ...

Patient Prosthesis Mismatch After SAVR and TAVR
Frontiers in Cardiovascular Medicine, 2022 Patient-prosthesis mismatch (PPM) remains one out of many factors to be considered during decision-making for the treatment of aortic valve pathologies. The idea of adequate sizing of a prosthetic heart valve was established by Rahimtoola already in 1978.

Long-term survival after aortic valve replacement with the Mitroflow bioprosthesis : a comparative study [PDF]
, 2019 Background Recent case reports of early structural degeneration of the Mitroflow valve have cast doubts on the suitability of this bioprosthesis, particularly in the smaller sizes, and in younger patients.

Remote Ischemic Preconditioning Neither Improves Survival nor Reduces Myocardial or Kidney Injury in Patients Undergoing Transcatheter Aortic Valve Implantation (TAVI) [PDF]
, 2020 BACKGROUND: Peri-interventional myocardial injury occurs frequently during transcatheter aortic valve implantation (TAVI). We assessed the effect of remote ischemic preconditioning (RIPC) on myocardial injury, acute kidney injury (AKIN) and 6-month ...
