Raised Prosthetic Valve Gradients: What Should be the Approach?

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2019
The introduction of valve replacement surgery has dramatically improved the outcome of patients with valvular heart disease. Echocardiography plays an important role to determine the outcome of the surgery and follow up of these patients with prosthetic ...

Evolving technology: the TRIFLO tri-leaflet mechanical valve without oral anticoagulation: a potential major innovation in valve surgery

Frontiers in Cardiovascular Medicine, 2023
The aortic valve is the most frequently diseased valve and aortic stenosis (AS) is the most prevalent valvular heart disease in developed countries. The diseased native aortic valve can be replaced by either a biological or mechanical valve prosthesis ...

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.

Transcatheter aortic-valve replacement for inoperable severe aortic stenosis. [PDF]

, 2012
BACKGROUND: Transcatheter aortic-valve replacement (TAVR) is the recommended therapy for patients with severe aortic stenosis who are not suitable candidates for surgery. The outcomes beyond 1 year in such patients are not known.

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 ...
