BACKGROUND Bleeding is the most frequent cause of preventable death after severe injury. Coagulopathy associated with severe injury complicates the control of bleeding and is associated with increased morbidity and mortality in trauma patients. The causes and mechanisms are multiple and yet to be clearly defined. METHODS Articles addressing the causes and(More)
R apid progress in trauma care occurs when the results of translational research are promptly integrated into clinical practice. Experience with a high volume of severely injured casualties expedites the process. 1 Historically, these conditions have converged during times of conflict, improving the care of combat casualties and subsequently that of(More)
AIMS Dysfunction of valved conduits in the right ventricular outflow tract (RVOT) limits durability and enforces repeated surgical interventions. We report on our combined two-centre experience with percutaneous pulmonary valve implantation (PPVI). METHODS AND RESULTS One hundred and two patients with RVOT dysfunction [median weight: 63 kg (54.2-75.9 kg),(More)
BACKGROUND Bleeding is one of the leading causes of preventable death after traumatic injury. Trauma-associated coagulopathy complicates the control of bleeding. The published approaches on the management of this coagulopathy differ significantly. METHODS A qualitative international survey of clinical practice among senior physicians responsible for the(More)
A precise and rapid procedure employing gel filtration on Superose-12 to measure the tetramer-dimer dissociation constants of some natural and recombinant hemoglobins in the oxy conformation is described. Natural sickle hemoglobin was chosen to verify the validity of the results by comparing the values with those reported using an independent method not(More)
BACKGROUND To treat the coagulopathy of trauma, some have suggested early and aggressive use of cryoprecipitate as a source of fibrinogen. Our objective was to determine whether increased ratios of fibrinogen to red blood cells (RBCs) decreased mortality in combat casualties requiring massive transfusion. METHODS We performed a retrospective chart review(More)
OBJECTIVE Down syndrome is frequently associated with complete atrioventricular septal defect. The aim of this retrospective study was to evaluate the impact of Down syndrome on morphologic features, surgical management, and perioperative and long-term mortality in patients with complete atrioventricular septal defect. METHODS Between October 1974 and(More)
OBJECTIVES Intracardiac thrombus formation is suspected to be a specific sequela after the Fontan operation and is difficult to determine by means of routine transthoracic echocardiography. The aim of our study was to evaluate the occurrence of intracardiac thrombi in the different types of Fontan modifications and to identify predisposing risk factors. (More)
BACKGROUND Human urotensin II (hU-II) is a potent vasoactive peptide possibly involved in pulmonary hypertension. Because the signaling mechanisms activated by this peptide in the pulmonary vasculature are largely unknown, we investigated the role of hU-II in the activation of NADPH oxidase and the control of redox-sensitive kinase pathways, expression of(More)
The coagulopathy of trauma is a syndrome of non-surgical bleeding from mucosal lesions, serosal surfaces, and wound and vascular access sites associated with serious injury, hypothermia, acidosis, hemodilution, and occasionally with classic disseminated intravascular coagulation (DIC). It can be largely explained by the effects of cold on platelet function,(More)
