1. Comparison of vena cava distensibility index and pulse pressure variation for the evaluation of intravascular volume in critically ill children
Abstract Objective: In this study, the authors aimed to evaluate the effectiveness of the vena cava distensibility index and pulse pressure variation as dynamic parameters for estimating intravascular volume in critically ill children. Methods: Patients aged 1 month to 18 years, who were hospitalized in the present study’s pediatric intensive care unit,

2. Adventitial Collagen Cross-Linking by Glutaraldehyde Reinforcing Human Saphenous Vein - Implication for Coronary Artery Bypass Grafting
ABSTRACT Introduction: A weak venous wall is one of the major reasons contributing to vein graft failure after coronary artery bypass grafting (CABG). We investigated whether adventitial collagen cross-linking by glutaraldehyde reinforces venous wall, preserving the endothelium of veins during high-pressure distention. Methods: Human saphenous veins (SVs)

3. Short-term outcome of Polytetrafluoroethylene Membrane Valve versus Transannular Pericardial patch Reconstruction of Right Ventricular Outflow Tract in Tetralogy of Fallot : a Randomized Controlled Trial
Abstract Introduction: Reconstruction of right ventricular outflow tract during primary repair of tetralogy of Fallot often requires the placement of a transannular patch which results in pulmonary regurgitation (PR). We compared the short-term outcomes of bicuspid polytetrafluoroethylene membrane valve versus transannular pericardial patch reconstruction o

4. Cardiovascular involvement in COVID-19: not to be missed
Abstract In December 2019, a striking appearance of new cases of viral pneumonia in Wuhan led to the detection of a novel coronavirus (SARS-CoV2). By analyzing patients with severe manifestations, it became apparent that 20 to 35% of patients who died had preexisting cardiovascular disease. This finding warrants the important need to discuss the influence of

5. COVID-19: A Matter Close to the Heart
Abstract Background: Hepatic congestion is a frequent finding in patients with heart failure (HF). Physical examination has limitations in quantifying systemic congestion and requires correlation with echocardiographic and laboratory data (usually B-type natriuretic peptide, BNP, or N-terminal pro-B type natriuretic peptide, NT-proBNP). Hepatic elastography

8. Impact of Vacuum-Assisted Venous Drainage on Forward Flow in Simulated Pediatric Cardiopulmonary Bypass Circuits Utilizing a Centrifugal Arterial Pump Head
Abstract Objective: To analyze the impact of vacuum-assisted venous drainage (VAVD) on arterial pump flow in a simulated pediatric cardiopulmonary bypass circuit utilizing a centrifugal pump (CP) with an external arterial filter. Methods: The simulation circuit consisted of a Quadrox-I Pediatric oxygenator, a Rotaflow CP (Maquet Cardiopulmonary AG, Rastatt

9. Hemodynamic variables in piglets anesthetized with isoflurane or propofol, kept under spontaneous ventilation and FIO2 of 0.5
RESUMO O objetivo deste estudo foi avaliar comparativamente os efeitos do propofol ou do isoflurano sobre as variáveis hemodinâmicas em leitões que receberam fração inspirada de oxigênio (FIO2) de 0,5 sob ventilação espontânea. Dezesseis leitões, pesando 16±1,1kg, foram divididos aleatoriamente em dois grupos: GI (isoflurano e FIO2 de 0,5) e GP (p

11. Revascularização venosa via transposição de veia gonadal esquerda em síndrome de nutcracker posterior: relato de caso
Resumo A síndrome de nutcracker é manifesta na presença de um aprisionamento sintomático da veia renal esquerda entre a aorta abdominal e a artéria mesentérica superior. Uma variação mais efêmera desta desordem é dita síndrome de nutcracker posterior, quando a compressão da veia renal não mais ocorre frontalmente à aorta, mas posteriormente a e

12. Clinical and blood gas analysis of calves conceived by artificial insemination, in vitro fertilization and animal cloning
RESUMO: Para que ocorra adaptação extra-uterina bem sucedida é necessário que o neonato consiga estabelecer suas funções respiratórias de maneira eficaz, garantindo oxigenação eficiente e boa vitalidade. Distúrbios respiratórios são os maiores causadores de óbito durante o período neonatal em bovinos, e essa mortalidade é ainda mais expressiva
