The role of myocardial fibrosis and ventricular mechanical dyssynchrony in the pathogenesis and treatment of contractile myocardial dysfunction.
… Although the development of systolic left ventricular impairment has been linked with a number of causative factors, the pathophysiological cascade between these initiators of myocardial dysfunction and its overt manifestation has been incompletely characterised. Amongst the proposed …

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 …

Mechanisms by which cardiac resynchronisation therapy improves cardiac performance in heart failure
This thesis assesses the mechanisms by which biventricular and left ventricular pacing improves cardiac performance in patients with heart failure. We demonstrated for the first time that CRT results in an improvement in acute haemodynamic variables in heart failure patients with a narrow QRS …

New methods for quantifying the synchrony of contraction and relaxation in the heart
… electrocardiogram QRS duration as a measure of dyssynchrony. However, up to 30% of patients selected for CRT show no improvement. This poor response rate may in part be explained by the poor correlation between mechanical dyssynchrony and QRS duration. Thus, better methods to quantify mechanical …
