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 ...

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 ...

Estimation of elastic and viscous properties of the left ventricle based on annulus plane harmonic behavior [PDF]
, 2006 Assessment of left ventricular (LV) function with an emphasis on contractility has been a challenge in cardiac mechanics during the recent decades. The LV function is usually described by the LV pressurevolume (P-V) diagram. The standard P-V diagrams

Dose Impaired Relaxation of Left Ventricle Affect Early Outcomes [PDF]
Acta Medica Iranica, 2010 Although systolic dysfunction is revealed as a prognostic factor in cardiac surgery , the role of diastolic dysfunction as a predictive factor is less evaluated. In this retrospective study from 872 patients that underwent isolated coronary artery bypass

Journal of the American College of Cardiology, 2009 Heart failure with normal ejection fraction (HFNEF) is a common presentation in elderly persons and seems to have a prognosis almost as bleak as systolic heart failure. Much work on the pathophysiology of this entity has focused on left ventricular (LV) stiffness ([1][1])—indeed, stiffening ...

Aortic valve stenosis: Prognosis and therapy [PDF]
Vojnosanitetski Pregled, 2003 There is a long latent period in the clinical course of aortic valve stenosis in adults. Symptoms usually occur in the case of critical stenosis, when aortic orifice area is under 0.7cm2 (0.4 cm2/m2).
