Near-infrared spectroscopy (NIRS) is used to monitor regional cerebral oxygenation (rScO2) during cardiac surgery but is less established during non-cardiac surgery. This systematic review aimed (i) to determine the non-cardiac surgical procedures that provoke a reduction in rScO2 and (ii) to evaluate whether an intraoperative reduction in rScO2 influences postoperative outcome. The PubMed and ...

As the population continues to age, more older patients present themselves for surgical procedures. Not uncommonly, these patients have considerable multiorgan dysfunction. Fundamental knowledge of predisposing risk is imperative for the optimal perioperative care of such patients. This review considers available data on factors that affect perioperative cardiac risk as they apply to specific c...

Cardiac resynchronization therapy (CRT) addresses abnormal left ventricular (LV) activation that produces detrimental effects on cardiac systolic and diastolic function. CRT improves symptoms and ventricular performance, promotes reverse remodeling, and decreases mortality and hospitalization in patients with congestive heart failure (CHF). Atrial-synchronized biventricular stimulation reverses...

BACKGROUND Several risk factors have been shown to increase mortality in cardiac surgery. However, the importance of left ventricular end-diastolic pressure (LVEDP) as an independent risk factor before cardiac surgery is unclear. Method. This observational study investigated 3024 consecutive adult patients who underwent cardiac surgical procedures at the Montreal Heart Institute from 1996 to 20...

Background: The purpose of this study was to investigate efficacy of high dose vitamin D in improving left ventricular ejection fraction (LVEF) in thalassemia patients with heart failure and vitamin D deficiency. Materials and Methods: This clinical trial study was conducted on 16 chronically transfused thalassemia patients and ventricular dysfunction with vitamin D deficiency between December...

introduction: heart failure is a major hazard for public health. despite recent advance in medical therapy, there is not enough information on the outcome of off-pump coronary artery bypass (opcab) and medical therapy on the patients with severe ventricular dysfunction and triple-vessel (cad). this study aimed to compare treatment outcomes and mortality rate in patients undergoing off-pump coro...

conclusions for laterally localized and protruded duodenal diverticula, laparoscopic resection is a feasible and safe method. the role of laparoscopy in surgical treatment of complicated diverticula, located in other parts of the duodenum, is unclear because of lack of experience. case presentation in this article, we present a case report of a large duodenal diverticulum, treated with laparosc...

P harmacologic management of patients with cardiac arrest or cardiogenic shock may be insuI cient in restoring adequate circulatory support. This has led physicians to investigate and develop more aggressive interventions for these problems. Cardiogenic shock most frequently occurs in the following clinical settings: (1) acute myocardial infarction; (2) postcardiotomy; (3) an acute exacerbation...
