Intracardiac pressures were simultaneously recorded in all cardiac chambers in anesthetized intact dogs during periods of volume overload produced by infusion of a blood saline mixture. The right and left intracardiac pressures increased simultaneously during the interval of infusion with the left side greater than the right side. The administration of a positive myocardial inotropic drug resul...

INTRODUCTION Intra cardiac tumours and tumour thrombi can present in a manner resembling a massive pulmonary embolism. Intravascular leiomyomatosis with intracardiac extension is one such rare tumour. Survival from obstructive shock in this condition has not been previously reported. CASE PRESENTATION A case is presented of a female who presented with recurrent syncope, cyanosis and then circ...

Massive intracardiac and intravascular thrombosis is a rare complication following cardiopulmonary bypass (CPB). Most of the cases of the disseminated thrombosis have been reported in patients undergoing complex cardiac surgeries and those receiving antifibrinolytic agents during CPB. We report the occurrence of disseminated intravascular and intracardiac thrombosis after CPB in a patient under...

At electrophysiologic study in a patient with the Wolff-Parkinson-White syndrome, intracardiac catheter recordings demonstrated a deflection that occurred 30 ms before ventricular activation. The rapid deflection was present during ventricular preexcitation but not during normal atrioventricular conduction. All QRS complexes were preexcited to varying degrees during atrial fibrillation, yet the...

Introduction Intracardiac blood flow measurements using 4D Phase Contrast CMR (4D PC-CMR) may contain useful information about cardiac pumping. Lagrangian Coherent Structures (LCS) is a new, operator-independent method which can simplify analysis by partitioning the flow into regions with different origins and destinations. Since LCS are operator-independent, they may be used to define quantita...

Purpose: Intracardiac flow analysis utilizing non invasive imaging methods is an increasingly attractive approach to evaluate cardiac function.
