Fluid-structure interaction simulation of prosthetic aortic valves : comparison between immersed boundary and arbitrary Lagrangian-Eulerian techniques for the mesh representation [PDF]

, 2016
In recent years the role of FSI (fluid-structure interaction) simulations in the analysis of the fluid-mechanics of heart valves is becoming more and more important, being able to capture the interaction between the blood and both the surrounding ...

Study of mitral valve in human cadaveric hearts

Heart Views, 2012
The mitral valve is a complex structure that is altered by disease states. The classical image of the mitral valve is a bicuspid valve with two leaflets and two papillary muscles. The reason for the present study is to study the morphology and morphometry of the mitral valve.This study was carried out on 116 human cadaveric hearts.

Left Ventricular Outflow Tract Geometry as a Predictor of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation Using the Evolut Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Predicting the need for permanent pacemaker implantation (PPM) after transcatheter aortic valve implantation (TAVI) is crucial for procedural planning and patient counseling. Aims To evaluate whether left ventricular outflow tract (LVOT) morphology, specifically a tapered configuration, predicts conduction disturbances requiring PPM

Automatic calcium scoring in low-dose chest CT using deep neural networks with dilated convolutions

, 2018
Heavy smokers undergoing screening with low-dose chest CT are affected by cardiovascular disease as much as by lung cancer. Low-dose chest CT scans acquired in screening enable quantification of atherosclerotic calcifications and thus enable ...

MELD score predicts outcomes in patients with advanced heart failure: A longitudinal evaluation

ESC Heart Failure, Volume 12, Issue 2, Page 839-847, April 2025.
Abstract Aims Advanced heart failure (AHF) is characterized by recurrent episodes of haemodynamic instability and frequent hospitalizations, leading to a progressive decline in quality of life and high mortality rates. The objectives of this study were to evaluate the effect of the model for end‐stage liver disease (MELD) score and its variations in ...

Plástica da valva mitral em pacientes consecutivos: como é a evolução tardia?: avaliação clínica e ecocardiográfica Mitral valve reconstruction: long-term follow-up

Brazilian Journal of Cardiovascular Surgery, 1991
Foram estudados no pós-operatório tardio 39 pacientes submetidos a plástica da valva mitral por insuficiência ou dupla lesão. A idade média dos pacientes foi de 30,5 anos com desvio padrão de 17,2 anos sendo 24 (61,50%) pacientes do sexo feminino e 15 ...

Effect Of Coronary Bypass And Valve Structure On Outcome In Isolated Valve Replacement For Aortic Stenosis [PDF]

, 2012
Reports differ regarding the effect of concomitant coronary artery bypass grafting (CABG) in patients who undergo aortic valve replacement (AVR) for aortic stenosis (AS), and no reports have described the effect of aortic valve structure in patients who ...

On-pump fibrillating heart mitral valve replacement with the SAPIEN  XT transcatheter heart valve [PDF]

European Journal of Cardio-Thoracic Surgery, 2013
In some high-risk patients, standard mitral valve replacement can represent a challenging procedure, requiring a risky extensive decalcification of the annulus. In particular, high-risk redo patients and patients with a previously implanted transcatheter aortic valve, who develop calcific mitral disease, would benefit from the development of new ...

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...
