d i ( i a f r i v g ( Unraveling the mysteries of cardiac contraction has been a major preoccupation of the cardiac investigators. More recently, the right ventricle is in focus, especially the right ventricle in the systemic position. The differences between the right and the left ventricles in myocardial architecture, blood supply, metabolism, response to loading conditions, and embryological...

The purpose of this investigation was to analyze how left ventricular assist device (LVAD) with a centrifugal pump alters left ventricular diastolic hemodynamics and energy by means of a left ventricular pressure volume relationship. Fifteen anesthetized normal pig hearts were studied after placement of an apical drainage LVAD with a centrifugal pump. Indices of the left ventricular isovolumic ...

External ventricular drainage (EVD) is frequently used in neurosurgery to drain cerebrospinal fluid in patients with raised intracranial pressure. We performed a retrospective single center study in order to evaluate the incidence of EVD-related infections and to identify underlying risk factors. 246 EVDs were placed in 218 patients over a 30-month period. EVD was continued in median for 7 days...

BACKGROUND Intraventricular haemorrhage (IVH) causes blockage of ventricular conduits leading to hydrocephalus, increased intracranial pressure (ICP), and a reduced level of consciousness. The current standard management of IVH is insertion of an external ventricular drainage (EVD) catheter. However, this procedure addresses only the problems of acute hydrocephalus and raised ICP. Endoscopic wa...

the aim of this study is to evaluate how far lempel-ziv complexity (lzc) of the binary symbolic sequences resulting from static or dynamic transformation (partitioning first-order difference) of the short-term electrocardiogram (ecg) signals (only 2 seconds duration) has the  potential in discriminating normal and ventricular tachycardia/ventricular fibrillation (vt/vf) subjects. the statistica...

conclusions chronic smoking caused left ventricular diastolic dysfunction. acute intake caused left and right ventricular diastolic dysfunction. changes persisted up to 30 minutes after smoking, although diastolic blood pressure returned to normal state. objectives the current study aimed to evaluate the acute and chronic effects of smoking on the left and right ventricular (rv) diastolic funct...

Adult T cell leukemia/lymphomas are aggressive disorders, which infiltrate not only the bone marrow but extensively the visceral organs as well. A case with left ventricular systolic dysfunction with myocardial infiltration and massive pericardial effusion which was demonstrated with echocardiography is discussed. The patient responded well to pericardial drainage and subsequent chemotherapy. T...

A unique case of infradiaphragmatic total anomalous pulmonary venous return in a 10-year-old girl is described. A persistent ductus arteriosus, ventricular septal defect, and large atrial septal defect were also present. Corrective surgery was performed at 10 years of age, with an excellent clinical result. The factors which permitted this unprecedented period of survival included non-obstructe...
