ventriculoperitoneal (vp) shunt placement that diverts the cerebrospinal fluid (csf) into the peritoneal cavity is the most common method of treatment of hydrocephalus. this shunt has a high incidence of malfunction mainly due to catheter obstruction or infection. about 20% of these complications are abdominal that may occur at any time after shunt placement from 1 week to several years. this s...

Intracoronary ECG was invented in 1974 and in 1985 it was shown for the first time that intracoronary wire could be used as an ECG unipolar lead to detect ongoing ischemia in humans. Intracoronary ECG still remains highly underused technique for guiding percutaneous coronary interventions. This article summarizes studies dating from 1974 through 2016 showing intracoronary ECG usefulness in find...

background: dilated cardiomyopathy is associated with a progressive deterioration in cardiac function and eventually death. initial interest in this hypothesis was to create another large animal model for dilated cardiomyopathy in addition to pigs and dogs . methods: after the induction of anesthesia to 10 female sheep, a carotid-jugular shunt was created in all the animals via a 1-cm fistula b...

BACKGROUND Experimental studies have demonstrated that intracoronary platelet aggregation and thrombus formation may induce marked vasoconstriction of epicardial arteries with endothelial injury. METHODS AND RESULTS To examine the effects of intracoronary thrombus formation on coronary vasomotor tone of human epicardial arteries in vivo, we studied 15 patients who developed intracoronary thro...

Introduction: We aimed at evaluating the clinical, laboratory and echocardiography effects of intracoronary administration of autologous bone marrow stem cell transplantation in different clinical entities of chronic Heart Failure (HF) patients.   Methods: This procedure was carried out during an interventional study conducted in the Cardiology department from JAN 2012 to APR 2013. The HF ...
