Abstract Objective Timing and causes of hospital mortality in adult patients undergoing veno-arterial extracorporeal membrane oxygenation (V-A ECMO) have been poorly described. Aim of the current review was to investigate..

Abstract Objectives: Cardiac surgery using cardiopulmonary bypass frequently provokes a systemic inflammatory response syndrome. This can lead to the development of low cardiac output syndrome (LCOS). Both of these can..

Abstract Introduction Cardiopulmonary bypass (CPB) is a common procedure to maintain body perfusion during cardiac surgery. It is associated with a systemic inflammatory response, hemostasis and circulatory dysfunction that can..

Abstract Background We sought to determine differences in the circulating metabolic profile of infants with or without acute kidney injury (AKI) following cardiothoracic surgery with cardiopulmonary bypass (CPB). Methods We..

Abstract Background Cerebral autoregulation mechanisms help maintain adequate cerebral blood flow (CBF) despite changes in cerebral perfusion pressure. Impairment of cerebral autoregulation, during and after cardiopulmonary bypass (CPB), may increase..

Abstract The importance of teamwork in health care delivery and patient safety is increasingly being recognized and has benefitted substantially by adopting a human factors' perspective and approach. The scientific..

Abstract Objectives: Cardiopulmonary bypass surgery is complicated by metabolic acidosis, microvascular dysfunction, and capillary leak. The glycocalyx—a layer of proteins and sugars lining the vascular endothelium—is degraded during cardiopulmonary bypass...

Abstract Background Recurrent observation of clot in the cardiopulmonary bypass circuit after the administration of a protamine test dose (PTD) prompted concern over the effects of PTDs on patient activated..

Abstract Systemic hypertension (HTN) is a recognized complication of veno-venous (VV) extracorporeal membrane oxygenation (ECMO) in children. We sought to determine the prevalence and associated features of HTN in a..

Abstract A prospective, observational single-center study was carried out. Pediatric patients undergoing congenital heart defect surgery were evaluated before, during, and after surgery. At each time point, sublingual microcirculation and..

Abstract Objective after cardiac surgery can be difficult to assess, often requiring invasive measurements. Bioelectrical impedance vector analysis (BIVA) is based on patterns of resistance (R) and reactance (Xc), corrected..

Abstract Introduction: Minimally invasive aortic valve replacement (MIAVR) requires changes in cannulation strategy and cardiopulmonary bypass (CPB) management when compared to the conventional approach (CAVR). We aimed at evaluating if..

Very little is known about tricuspid valve when compared to other valves, and tricuspid stenosis is rarely described. It most often co-exists with mitral valve pathology especially in patients with..

Uhl's Anomaly is a rare cardiac condition in which there is total absence of right ventricular myocardium resulting in apposition of the endocardium and epicardium. We report a case of..

A single ventricle is an uncommon occurrence in embryogenesis, which results in the anatomical or functional loss of a ventricular cavity. These malformations are life-threatening and necessitate quick revision to..
