A coupled mitral valve -- left ventricle model with fluid-structure interaction

, 2017
Understanding the interaction between the valves and walls of the heart is important in assessing and subsequently treating heart dysfunction. With advancements in cardiac imaging, nonlinear mechanics and computational techniques, it is now possible to ...

Prognostic value of echocardiographic indices of left atrial morphology and function in dogs with myxomatous mitral valve disease [PDF]

, 2018
Background: The prognostic relevance of left atrial (LA) morphological and functional variables, including those derived from speckle tracking echocardiography (STE), has been little investigated in veterinary medicine.

Balloon‐Expandable Versus Self‐Expanding Valves in Bicuspid Aortic Stenosis: Insights From the SWEDEHEART Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve replacement (TAVR) is increasingly used in patients with bicuspid aortic valve (BAV) stenosis, but there is limited comparative data on balloon‐expandable (BEV) versus self‐expanding valves (SEV) in this population. Aim To compare clinical and hemodynamic outcomes between BEVs and SEVs in patients with BAV

Analysis of Echocardiography Images Using Grid Independent Technique for Patients with Mitral Valve Problems (MVP) [PDF]

, 2011
With echocardiography images collected by a transthoracic transducer, can be used to evaluate the mitral valve problems. Incorrect surgical of mitral valves failure will cause death and the surgical repair can be improved by knowing the correlations ...

Impact of Heart Failure and Chronic Kidney Disease on All‐Cause Mortality in Patients Undergoing Coronary Angiography: Results From the Finnish Kardio Multicentre Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Heart failure (HF) and chronic kidney disease (CKD) are common comorbidities among patients undergoing coronary angiography. Both conditions are associated with increased risk of adverse cardiovascular outcomes and mortality. However, the joint prognostic impact of HF and CKD in this patient population remains unclear. Aims We aimed

Computational Analysis: Fluid Structure Interaction Model Of The Mitral Valve Leaflet [PDF]

, 2010
In the mitral valve, regional variations in structure and material properties combine to affect the biomechanics of the entire valve. Previous study, we know that mitral valve leaflet tissue is highly extensible.

Feasibility and Safety of Transfemoral Aortic Valve Replacement Using Local Anesthesia in the Catheterization Suite Versus General Anesthesia in the Operation Theater

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background For over a decade, transfemoral transcatheter aortic valve replacements (TF‐TAVR) have been performed at the University Hospital of Nancy. A minimalistic approach to TF‐TAVR, conducted without general anesthesia and entirely percutaneously in a catheterization suite (simplified approach), has been reported to be as safe and ...

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 ...

Two‐Year Results of Percutaneous Endocardial Septal Radiofrequency Ablation for Hypertrophic Obstructive Cardiomyopathy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Hypertrophic obstructive cardiomyopathy (HOCM) is a hereditary myocardial disease. Percutaneous endocardial septal radiofrequency ablation (PESA) is an innovative approach for treating HOCM. Consequently, we present the outcomes of the PESA for HOCM. Methods This study included 20 patients with HOCM who received PESA.

Transcatheter Management of Severe Paravalvular Leak in the Inferior Vena Cava Prosthesis of the TricValve Bicaval Valve System

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We present a 74‐year‐old female with a history of mechanical aortic and mitral valve implantation and non‐Hodgkin lymphoma. She presented with right sided heart failure due to severe functional tricuspid regurgitation and was treated with transcatheter TricValve bicaval system implantation.
