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

Effects of heart valve prostheses on phase contrast flow measurements in cardiovascular magnetic resonance - a phantom study [PDF]
, 2017 BACKGROUND: Cardiovascular Magnetic Resonance is often used to evaluate patients after heart valve replacement. This study systematically analyses the influence of heart valve prostheses on phase contrast measurements in a phantom trial.

A successful pregnancy outcome after mitral valve replacement: a case report [PDF]
, 2023 Valvular heart disease can be acquired or congenital. Although the incidence of rheumatic heart disease is on the decline, the number of patients with congenital heart disease who survive into adulthood has grown substantially over the past 30 years ...

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.

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.

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 ...
