Staged surgical palliation and ventricular performance in functionally single ventricle anatomy
… the acute effect of surgical palliation on ventricular function in children with functionally single ventricle anatomy. Ventricular volume and pressure were measured using a combined pressure-conductance catheter. Initial laboratory-based experiments were performed using a physical model of …

Muscle Metaboreflex Control Of Cardiovascular Function In Hypertension
… (HTN), metaboreflex-mediated increases in ventricular function and CO are markedly attenuated during mild exercise. As sympathetic nerve activity (SNA) is exaggerated in both heart failure and HTN, it is plausible that the mechanisms mediating the attenuation of CO in HTN with muscle …

A theoretical study of left ventricular and heart muscle dynamics
… Further, the mechanical behaviour of the ventricular wall is synthesised from anatomical data concerning the cardiac muscle fibre structure of the wall. Its mechanical and dynamical properties are then, as in the physiological situation, dependent on those of the muscle fibre. These fibre …

Acoustic Radiation Force Impulse Imaging of Myocardial Performance
… diseases, it is necessary to assess myocardial performance and function. One mechanical property that has been shown to reflect myocardial performance is myocardial stiffness. Acoustic radiation force impulse (ARFI) imaging has been demonstrated to be capable of visualizing variations in local …

Parameters and algorithms to evaluate cardiac mechanics by conductance catheter
… particular, we present the phenomenon known as ventricular mechanical dyssynchrony: its impact on cardiac function, the therapy for its treatment and the methods for its quantification. Specifically, we describe the conductance catheter and its use for the measurement of dyssynchrony. At the end …
