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...
Medium-resolution satellite images have been widely used for the identification and quantification of irrigated areas by center pivot. These areas, which present predominantly circular forms, can be easily identified visual analyses these images. In addition to identifying quantifying pivot, other information that is associated fundamental producing cadastral maps. The goal this work was generate mapping pivots in State Minas Gerais, Brazil, with purpose supplying on agriculture. Using...
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%).
A sinus floor elevation via lateral window (LSFE) is one of the most widely used bone augmentation procedures for implant therapy in posterior area maxilla. Locating and preparing a correct opening on wall key step this procedure. Conventionally, surgeon designs locates after flap reflected based information obtained from cone-beam computed tomography (CBCT) images or other diagnostic aids. Nevertheless, spite advancements CBCT imaging, clinicians may still experience hardships situating...
The Sequential Organ Failure Assessment (SOFA) score is a predictor of mortality in ICU patients. Although it widely used and has been validated as reliable independent morbidity cardiac ICU, few studies correlate early postoperative SOFA with long-term survival.Retrospective observational cohort study.Tertiary academic surgery ICU.One-thousand three-hundred seventy-nine patients submitted to surgery.SOFA 24 hours, 48 mean, highest scores were correlated survival at 12 months. Wilcoxon tests...
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...
Abstract OBJECTIVES Activated clotting time (ACT) is commonly used to monitor anticoagulation during cardiac surgeries. Final ACT values may be essential predict postoperative bleeding and transfusions, although ideal remain unknown. Our aim was evaluate the utility of as a predictor transfusion use. METHODS Retrospective study (722 patients) submitted surgery between July 2018–October 2021. We compared patients with final &lt; basal ≥ 140 s ≥140 s. Continuous variables were analysed...

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,...
Abstract Introduction The natural history in aortic stenosis (AS) is a slowly progressive process which begins as sclerosis and subsequently progresses to severe opening restriction, conditioning symptoms development. At this time, surgical valve replacement strongly recommended due its poor prognosis. Purpose Evaluation of predictor factors symptomatic AS prognostic impact. Methods Single center retrospective analysis patients' data accompanied cardiology consultation diagnosed between...
Abstract Introduction The prognostic value of pharmacologic stress echocardiography has been extensively demonstrated in patients undergoing noncardiac surgery since 42% the perioperative complications are cardiac. Coronary artery stenoses can became flow-limiting due to hemodynamic fluctuations this period leading myocardial ischemia. Purpose Evaluation preoperative risk stratification. Methods Single center retrospective analysis patients’ data referred perform a stratification through...
OBJECTIVES: Cardiac surgery is frequently associated with significant postoperative bleeding. Platelet-dysfunction the main cardiopulmonary bypass (CPB)-induced hemostatic defect. Not only number of platelets decreases, but also remaining are functionally impaired. Although lipid metabolism crucial for platelet function, little known regarding metabolic changes CPB-dysfunction. Our aim to explore possible contribution perturbations dysfunction after cardiac surgery. DESIGN: Prospective...
Abstract Background Despite recent advances, surgical aortic valve replacement (SAVR) remains the gold standard for most of patients with stenosis. The ageing population, increased comorbidities and rising minimally invasive techniques, led to development new prosthetic devices easier faster implantation. Purpose This study aimed analyse short long-term outcomes SAVR rapid-deployment (RD) bioprosthesis isolated stenosis Method Singe center, retrospective longitudinal cohort who underwent...
Abstract Background Multivalvular surgery (MV) requires prolonged extracorporeal circulation (ECC) and aortic cross-clamp times (X-Ao). Rapid-deployment prosthesis (RD-AV) allow lower ECC X-Ao in isolated valve (AVR), but have not been studied MV surgery. Purpose To determine if RD-AV use influences early outcomes when compared to biological stented or mechanical valves Methods Retrospectively collected pre, intra immediate post-operatory data on all adult patients with AVR operated our...
