The magnitude and time course of alterations in left ventricular size, end-diastolic pressure (LVEDP), and stiffness consequent to chronic volume overloading were examined in conscious dogs. A large infrarenal aortocaval shunt was produced surgically, left ventricular dimensions were measured by cineradiography using radiopaque beads implanted subendocardially, and LVEDP was measured via an ind...

Abstract So-called respectively readings have posed serious challenges for theories of syntax and semantics. Sentences like George and Martha respectively denounced and were denounced by the governor (McCawley 1998) show that although the conjoined verbal expressions share the same syntactic subject, they do not predicate that subject in the same way; George (not Martha) denounced the governor,...

Dilated cardiomyopathy (DCM) or round heart disease is a muscle disease of the heart which is characterized by ventricular dilatation and abnormal systolic and diastolic left ventricular function. In animals, including turkeys and humans, DCM is the major cause of morbidity and mortality which results from heart failure. In the turkey, DCM can be idiopathic or induced. Since idiopathic or spont...

BACKGROUND Benefits of cardiac resynchronisation therapy (CRT) for survival in selected congestive heart failure (CHF) patients have been acknowledged by the 2005 ESC guidelines. AIM To analyse mortality in CRT pacing only (CRT-P) patients during at least one-year follow-up. METHODS This was a prospective, multi-site, at least one-year observational study on mortality and mode of death in p...

Percutaneous mechanical circulatory support has traditionally been considered in patients with acute myocardial infarction (AMI), however, this technology is now being used for optimizing decompensated heart failure (ADHF). Widely accepted data on left ventricular recovery (LVR) focused the optimization of after durable assist devices (LVAD) but not described Impella. Current parameters definin...

To evaluate the prognostic significance of clinicopathological measurement in the diagnosis of acute myocardial infarction (MI) in sheep, acute MI was induced by ligation of left anterior descending coronary artery (LAD). For this purpose, twenty four healthy sheep were divided into the sham-operated or control group (group I, thoracotomy without MI) and the experimental group (group II, with M...

BACKGROUND In patients with left ventricular (LV) dysfunction the mitral leaflet coaptation point (CPMA) is displaced towards the LV apex. The aim of our study was to estimate the value of CPMA measurement as a simple index regarding the acute effects of cardiac resynchronization therapy (CRT), which is coming to be an established method of treatment for congestive heart failure (CHF). METHOD...

BACKGROUND Monitoring of the appearance of left ventricular hypertrophy (LVH) by echocardiography is currently recommended for in the management of children with End-stage renal disease (ESRD). In order to investigate the validity of this method in ESRD children, we assessed the intra- and inter-observer reproducibility of the diagnosis LVH. METHODS Echocardiographic measurements in 92 childr...
