Abstract OBJECTIVES Postoperative organ dysfunction is common after cardiac surgery, particularly when cardiopulmonary bypass (CPB) used. The Sequential Organ Failure Assessment (SOFA) score validated to predict morbidity and mortality in surgery. However, the impact of CPB duration on postoperative SOFA remains unclear. METHODS This a retrospective study. Categorical values are presented as percentages. comparison groups utilized Kruskal–Wallis chi-squared test, complemented by ad hoc...

Background/Objectives: The incidence of aortic stenosis (AS) is predicted to rise with the aging population, emerging as a growing public health challenge in developed countries, leading an increased demand for intervention. Our aim predict evolution proposed cases SAVR geographic referral area our tertiary hospital until 2041. Methods: We used data from Portuguese Census 2001, 2011, and 2021 analyze resident population within Cardiothoracic Surgery Department's area. Applying projection...

Background: Aortic valve stenosis remains the most prevalent valvular pathology in Western countries. Rapid deployment bioprosthesis (RD) has emerged as a promising alternative to conventional valves for surgical aortic replacement (SAVR), particularly elderly and high-risk patients. This study reports short- long-term outcomes of RD patients with isolated stenosis. Methods: A retrospective single-center analysis was conducted on 382 who underwent RD-AVR between 2014 2020. Data were...

To assess by Doppler echocardiography the structural and functional alterations of rat heart with surgical induced extensive myocardial infarction.Five weeks after ligature left coronary artery, 38 Wistar-EPM rats both sexes, 10 them infarction, undergone anatomical evaluation then euthanized for anatomopathological analysis.Echocardiography was 100% sensible specific to confirmed miocardial infarction. Extensive infarction lead dilatation ventricle (diastolic diameter: 0.89 cm vs.0.64 cm;...

Excess nitrogen in the ammonium form may induce different nutritional disorders plants depending on species cultivated. Therefore, objective herein was to evaluate accumulation of nutrients, growth and visual symptoms rice spinach function concentrations nutrient solution. Two experiments were performed with a greenhouse, at Unesp Campus Jaboticabal-SP, Brazil. In each experiment five used (10, 20, 40, 80 100 mmol L-1), arranged randomized block design repetitions. The effects excess ammonia...

Aortic stenosis is the most common valvular heart disease. The number of octogenarians proposed for intervention growing due to increased lifespan. In this manuscript we aim evaluate perioperative outcome and long-term survival after surgical aortic valve replacement (SAVR) in octogenarians, comparing patients with low risk (EuroscoreII <4%) intermediate-high ≥4%).

Growth Differentiation Factor 15 (GDF15) is an emerging biomarker that significantly increases during acute stress responses, such as infections, and moderately elevated in chronic inflammation-driven conditions. While evidence suggests high levels of GDF15 cardiac surgery are associated with worse outcomes, its utility evaluator early postoperative complications remains unclear. This study aims to characterize the profile patients undergoing isolated surgical aortic valve replacement,...

Aortic valve stenosis is the most common adult disease in industrialized countries. The aging population and increase comorbidities urge development of safer alternatives to current surgical treatment. Sutureless bioprosthesis has shown promising results, especially complex procedures patients requiring concomitant surgeries.Assess clinical hemodynamic performance, safety, durability Perceval® prosthetic valve.This single-center retrospective longitudinal cohort study collected data from all...

Bone fractures are not uncommon in paediatric age. However, when recurrent, an underlying clinical condition must be excluded. We describe the case of a boy aged 7 years, referred for investigation recurrent bone fractures. Personal and family histories were unremarkable. Physical examination was normal. Almost all primary disorders Additional laboratory investigations ruled out majority secondary causes fragility. Coeliac disease (CD) serologies, however, positive, duodenal biopsies...

Introduction Low mean arterial pressure (MAP) periods occur frequently during cardiopulmonary bypass (CPB), and their management remains controversial. Our aim was to correlate MAP CPB with the occurrence of post-operative acute kidney injury (AKI), considering two different parameters: consecutive cumulative low periods. Methods Single-centre observational retrospective study including 250 patients submitted non-emergent aortic valve replacement, tepid mild hypothermia (not below 32°C). The...

Tumors of the heart are uncommon, and lymphangiomas among rarest this group, with very few cases reported. These tumors consist a benign slow-flow vascular malformation.We report case man diagnosed incidentally pericardial mass our surgical approach for its treatment.The had no cleavage plane between myocardium tumor. Because this, rather than total resection, high operative risk, biopsy was preferred. The pathology specimen showed tumor patient referred to cardiologist regular...

Constrictive pericarditis is a clinical condition characterized by the appearance of signs and symptoms right heart failure due to loss pericardial compliance. Cardiac surgery now one most frequent causes in developed countries, while tuberculosis remains prevalent cause developing countries. Malignancy rare but usually has poor prognosis. The diagnosis constrictive challenge requires combination noninvasive diagnostic methods (echocardiography, cardiac magnetic resonance computed...

OBJETIVO: comparar a incidência de lesões neurológicas em cirurgias corretivas curvas rígidas escoliose idiopática, utilizando-se somente o teste do despertar e monitoração neurofisiológica intra-operatória por meio dos Potenciais Evocados Somato-Sensitivo (PESS). MÉTODOS: foram realizadas 111 para correção com instrumentação artrodese pela via posterior, no período janeiro 1985 maio 2001. Os procedimentos divididos dois grupos, sendo 80 pacientes operados sem intra-operatória, utilizando...

Anterior mediastinal tumours account for 50% of all masses. Surgical intervention is the standard approach their diagnosis or treatment. Minimally invasive techniques have gained significant popularity in last few decades due to obvious advantages that they offer. We will describe a series composed first 20 patients who were submitted new minimally video-assisted technique, which uses an inframammary incision involving Thoratrak rib spreader and Rultract Skyhook retractor.A retrospective...
