BACKGROUND Non-invasive assessment of volume and function on the right ventricle (RV) for pulmonary hypertension (PH) is limited. METHODS AND RESULTS Patients with PH (n=23) underwent 3-dimensional (D) echocardiography (3DECHO), with cardiac magnetic resonance imaging to confirm its precision, and right heart catheterization. On linear regression analysis the RV end-systolic volume index (ESV...
Persistent and long-standing persistent atrial fibrillation evolves from complex arrhythmogenic substrate and sources. Multiple studies have shown improved freedom from arrhythmia recurrences if sinus rhythm had been restored during the index ablation; however, such harder procedural endpoint requires laborious stepwise approach almost invariably pursuing non-pulmonary-vein sources. Longer-term...
BACKGROUND Renal hemodynamic measurements are complicated to perform in patients with cirrhosis, yet they provide the best measure of risk to predict hepatorenal syndrome (HRS). Currently, there are no established biomarkers of altered renal hemodynamics in cirrhosis validated by measured renal hemodynamics. METHODS In this pilot study, simultaneous measurements of glomerular filtration rate ...
Periodontal disease is associated with endothelial dysfunction of the brachial artery and hemodynamic alterations of the common carotid artery. Periodontal therapy improves endothelial function. It is not known if it is able also to improve the hemodynamics of the carotid artery. The aim of the current study was to evaluate the efficacy of 2 different periodontal treatments on carotid hemodynam...
Background and Aim: Hemodynamic stability during anesthesia and operation is the most important aim of anesthesiologists. Every anesthetic drug has its own hemodynamic effects. The interaction of these drugs with each other and with preoperative drugs of the patients, may cause critical changes in patient's hemodynamic status. For a perfect anesthesia induction, while using high doses of op...
BACKGROUND Considering the role of aging in brain atrophy and cerebral vascular demand, we carried out this study to clarify the role of aging in duplex indices of vertebral arteries. METHODS From June 2005 to June 2006, 96 volunteers with age range of 20 to 95 years, were evaluated with color doppler for duplex indices of vertebral arteries. Sever hemodynamic stenosis was excluded in all of ...
background surgeon’s depend to a large degree on the amount of blood loss and a clear view of the surgical field, when conducting endoscopic procedures in order to achieve satisfactory outcomes. the anesthesiologist’s choice of method for the induction and maintenance of anesthesia plays a major role in achieving this goal. objectives this study was performed in order to compare the two most we...
