Mitral valve replacement in infants and children 5 years of age or younger: Evolution in practice and outcome over three decades with a focus on supra-annular prosthesis implantation [PDF]
, 2008 ObjectiveSuccessful mitral valve replacement in young children is limited by the lack of small prosthetic valves. Supra-annular prosthesis implantation can facilitate mitral valve replacement with a larger prosthesis in children with a small annulus, but

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 ...

Artificial Organs, Volume 47, Issue 1, Page 168-179, January 2023., 2023 Peak oxygen consumption, VO2peak, was associated with short‐term 3‐months‐rehospitalization in heart failure patients with reduced ejection fraction (HFrEF). Exercise oscillatory ventilation (EOV), representing fluctuations of pulmonary artery pressure, can be observed in heart failure patients with reduced ejection fraction with and without left ...

An echocardiographic comparison of sutureless and conventional aortic valve replacement : a matched case-control study [PDF]
, 2018 Background: Patients at a high operative risk for conventional aortic valve replacement (AVR) may be offered sutureless valve implantation. Sutureless valves resemble conventional valves but incorporate an anchoring mechanism without using annular ...

Controlled Comparison of Simulated Hemodynamics across Tricuspid and Bicuspid Aortic Valves [PDF]
, 2021 Bicuspid aortic valve is the most common congenital heart defect, affecting 1-2% of the global population. Patients with bicuspid valves frequently develop dilation and aneurysms of the ascending aorta. Both hemodynamic and genetic factors are believed to contribute to dilation, yet the precise mechanism underlying this progression remains under debate.

Artificial Organs, Volume 47, Issue 1, Page 129-137, January 2023., 2023 Device‐based therapies for heart failure with preserved ejection fraction are limited, but the left atrial assist device pump is making progress as one option. Since the implantation site is unique, options for device orientation, driveline exteriorization, and exit sites must be demonstrated.
