Improved Heatmap-based Landmark Detection [PDF]
, 2021 Mitral valve repair is a very difficult operation, often requiring experienced surgeons. The doctor will insert a prosthetic ring to aid in the restoration of heart function. The location of the prosthesis' sutures is critical. Obtaining and studying them during the procedure is a valuable learning experience for new surgeons.

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 ...

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.

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 ...
