Prediction of Turbulent Shear Stresses through Dysfunctional Bileaflet Mechanical Heart Valves using Computational Fluid Dynamics

, 2018
There are more than 300,000 heart valves implanted annually worldwide with about 50% of them being mechanical valves. The heart valve replacement is often a common treatment for severe valvular disease.

Transthoracic three-dimensional echocardiography for the assessment of straddling tricuspid or mitral valves [PDF]

, 2008
Background The advent of 3D echocardiography has provided a technique which, potentially, could afford significant additional information over conventional cross-sectional echocardiography in the assessment of patients with straddling atrioventricular ...

Which Method Best Predicts Postoperative Complications: Deep Learning, Machine Learning, or Conventional Logistic Regression?

Annals of Gastroenterological Surgery, EarlyView.
Deep learning has shown promise in predicting postoperative complications, particularly when using image or time‐series data. However, on tabular clinical data such as the NCD, it often underperforms compared to conventional machine learning. Integrating multimodal data may enhance predictive accuracy and interpretability in surgical care.

Transplante de valva mitral heteróloga: Nova alternativa cirúrgica: estudo clínico inicial Heterologous mitral valve transplant: New surgical technique: initial clinical trial

Brazilian Journal of Cardiovascular Surgery, 1993
A substituição da valva mitral tem sido realizada, nestes 30 anos, usando-se o modelo aórtico. Embora o resultado clínico, na maioria dos pacientes seja satisfatório, existem, restrições específicas, tanto entre as biopróteses, como nas próteses ...

A Rare Culprit of Infective Endocarditis in an IV Drug User: Burkholderia cepacia

Case Reports in Medicine, 2019
Infective endocarditis (IE) is an infection of the cardiac native or prosthetic valves typically caused by Staphylococcus aureus, viridans streptococci group, and coagulase-negative staphylococci. Risk factors include congenital heart disease, structural

The living aortic valve: From molecules to function. [PDF]

, 2014
The aortic valve lies in a unique hemodynamic environment, one characterized by a range of stresses (shear stress, bending forces, loading forces and strain) that vary in intensity and direction throughout the cardiac cycle.

"Pac-Man Heart" and Mitral Valve Prolapse

Journal of Cardiovascular Echography, 2021
A 50-year-old man accessed the echo laboratory for dyspnea. His medical history was unremarkable. Transthoracic two-dimensional echocardiogram showed a posterior leaflet of the mitral valve prolapse associated with eccentric regurgitant jet.

Factors associated with cardiovascular events after simultaneous liver–kidney transplant from the US Multicenter Simultaneous Liver–Kidney Transplant Consortium

Hepatology Communications, EarlyView., 2022
Abstract Cardiovascular disease is a leading complication after both liver and kidney transplantation. Factors associated with and rates of cardiovascular events (CVEs) after simultaneous liver–kidney transplant (SLKT) are unknown. This was a retrospective cohort study of adult SLKT recipients between 2002 and 2017 at six centers in six United Network ...
