The choice of a bioprosthetic valve substitute remains controversial with the major concern being primary tissue failure after implantation. We compared biological properties of the two most frequently used bioprosthetic valve materials, bovine peric

Modeling methods have been employed to further characterize the physical and physiologic processes of filling and diastolic function. They have led to more detailed understanding of the effect of alteration of physiologic parameters on the Doppler E-

Cardiovascular dynamics is a field in which modelling and systems analysis have formed an extremely important discipline. For example, understanding of even such a fundamental function of the circulation as the relationship between central venous pre

To study cardiac mechanics, it is important to study the beat-to-beat changes in the heart. Left ventricular diastolic filling properties are determined by a passive component and an active component due to ventricular relaxation that occur simultane

This study supports a mathematical model and previous findings indicating that , the time from onset of contraction to , reflects the time-dependent aspects of contraction and hence decreases with increasing contractility. Combined data from 20 consc

A mathematical model of left ventricular pressure (LVP) during isovolumic contraction in the time domain shows the following predictions: 1) td, the time from onset of contraction to dP/dtmax and (dP/dt)/P, reflect only the time-dependent aspects of

This article presents a didactic approach toward understanding the complex relations between transmitral flow patterns and cardiac properties. We start with some observations, obtained noninvasively, from normal and diseased human hearts, and supplem

BACKGROUND The importance of the contribution of atrial systole to ventricular filling in mitral stenosis is controversial. The cause of reduced cardiac output following the onset of atrial fibrillation may be due to an increased heart rate, a loss o
