Parameters and algorithms to evaluate cardiac mechanics by conductance catheter
… quantification. Specifically, we describe the conductance catheter and its use for the measurement of dyssynchrony. At the end of the Section 1, we propose a new set of indexes to quantify the dyssynchrony that are studied and validated thereafter. In Section 2 we describe the studies carried …

Studies in right ventricular function: Employing the conductance catheter method for ventricular volume determination
… of right ventricular function using the conductance catheter method to measure real-time continuous right ventricular volume. The initial part of the thesis, chapters 2 and 3,, deals with the 2 accuracy and limitations of the conductance method in measuring right ventricular volume. In …

Staged surgical palliation and ventricular performance in functionally single ventricle anatomy
… pressure were measured using a combined pressure-conductance catheter. Initial laboratory-based experiments were performed using a physical model of the left ventricle, which allowed examination of the measurement techniques used in the clinical studies but under controlled conditions. These …

Cardioprotective effects of Glucagon-like Peptide 1 (GLP-1) and their mechanisms
… ischaemia during GLP-1 infusion, assessed by conductance catheter. A further transient balloon occlusion is also used to assess the effect of supply ischaemia on RV function. Finally, the GOLD PCI study assesses whether GLP-1 protects against periprocedural myocardial infarction when …

Vergleich regionaler und globaler Kontraktilitätsparameter unter den Bedingungen der Inotropieänderung im normoperfundierten und ischämischen Myokard
… LV Druck und Volumen wurden mit einem Conductance-Katheter-Messmethode bestimmt. Die systolische Strainrate wurde Doppler-echokardiographisch als Rate der systolischen LV Wandverdickung des posterioren Myokards erfasst. Die koronare Minderperfusion wurde mittels eines speziellen …

Effekte der Inhalationsanästhetika Isofluran und Xenon auf die systolische und diastolische Ventrikelfunktion während Myokardischämie
… systolic and diastolic function were assessed by conductance catheter.RESULTS: Xenon and isoflurane did not impair cardiac output or arterial pressure, whereas xenon increased afterload. Nevertheless, both drugs demonstrated negative inotropic effects. Xenon affected the active relaxation and …
