Introdução: os instrumentos endodônticos confeccionados com uma liga de Níquel e Titânio foram importantes para a endodontia atual. Com o aprimoramento da metálica utilizada fabricação possibilitou automatização conferiu excelentes propriedades tais como melhor flexibilidade resistência fratura. Objetivos: discorrer por meio revisão literatura evolução dos níquel titânio, além fatores envolvidos nessa evolução, necessidade melhorar flexibilidade, durabilidade instrumentos. Metodologia: é...
Abstract Background Chronic total coronary occlusion (CTO) myocardial territories maintain perfusion via collateral circulation from adjacent vessels, thereby preventing transmural infarction and partially preserving ventricular function. The network may be categorized based on its angiographic characteristics, using either Rentrop or Werner classification, which used to evaluate the need for revascularization. Nevertheless, their relationship with ischemic burden is not entirely...
Abstract Background Chronic total coronary occlusion (CTO) poses a complex challenge in angiographic hemodynamics. Blood supply to the affected myocardium is dependent on formation of collateral network from adjacent vessels. However, this steal phenomenon reduces myocardial blood flow (MBF) remote myocardium, particularly under stress conditions. Limited data exist quantitative perfusion alterations both these regions following intervention. Purpose To assess effect percutaneous...
Abstract Funding Acknowledgements Type of funding sources: None. Introduction 3D left ventricular ejection fraction (LVEF) quantification methods are more accurate and reproducible than 2D echocardiography, however, conventional is time consuming requires extensive user expertise, thus hindering its routine implementation in busy echocardiography laboratories use by inexperienced physicians. HeartModel A.I. (HM) a simple, fast, recently validated automated analysis software that detects LV...
Abstract Background The long-term survival rates of myocardial infarction with non-obstructive coronary arteries (MINOCA) patients is lower than in the general population. Nevertheless, there are conflicting results regarding prognosis MINOCA comparison to obstructive artery disease (MI-CAD) patients. Purpose aim this study was assess all-cause mortality and compare it MI-CAD Methods Retrospective analysis 2443 consecutively admitted for acute (AMI), a single intensive care unit. Only 5...
Abstract Introduction Cardiopulmonary exercise testing (CPET) is recommended in patients with heart failure (HF) to optimize prescription and as part of the evaluation for transplantation. Recently, a new multivariable score (MVS) was proposed powerful method predict HF events an optimal cut-off value 120. Purpose We aimed evaluate prognostic this tool HF. Methods conducted single-centre study assessing consecutive who underwent CPET from 2013 2017. Classic recently variables were collected,...
Abstract Background Sodium fluoride (18F-NaF) uptake in positron emission tomography with computed (PET-CT) identifies active microcalcification both atherosclerotic plaques and the aortic valve. Purpose We aimed to evaluate global cardiac activity 18F-NaF, as a measure of burden, high cardiovascular (CV) risk patients. Additionally, an exploratory endpoint, we evaluated association between diastolic dysfunction. Methods High CV-risk individuals without previous CV events from single centre...
Abstract Background The prognosis of patients with myocardial infarction non-obstructive coronary arteries (MINOCA) is worse than that the general population. Nevertheless, predictors for a outcome in MINOCA are not fully determined. Purpose aim this study was to evaluate prognostic value C-Reactive Protein (CRP) patients. Methods Retrospective analysis 706 consecutively admitted due acute (AMI), whom angiography revealed absence obstructive artery disease (≥50% stenosis). CRP levels were...
Abstract Introduction Transcatheter edge-to-edge repair (TEER) has been proven to reduce cardiovascular events in a particular subset of patients with severe mitral insufficiency (MR) and left ventricle dysfunction. Nevertheless, its short long-term impact on the right (RV) remained be determined. Our goal was assess effect TEER RV chamber pressures. Methods Patients were consecutively enrolled from Nov 2018 Jul 2022. Clinical, laboratory echocardiographic procedural data collected....
Abstract Background Approaching the congestive patient is a complex task that requires combination of different assessment methods. The Strauss formula uses variations in haemoglobin and haematocrit to estimate plasma volume (PVV) haemoconcentration. However, this was only validated outpatients followed with chronic heart failure. We aimed assess applicability hospitalized patients for acute failure (AHF). Methods conducted single-centre, retrospective, observational study 302 who were...
Abstract Funding Acknowledgements Type of funding sources: None. Background After an ST-elevation myocardial infarction (STEMI), the risk subsequent cardiovascular events is high. Risk stratification at index hospitalization remains a core challenge, especially in patients with subtle changes LV function. Early systolic lengthening (ESL) may occur ischemic segments reduced contractile force and it has been correlated infarct size prognosis STEMI mildly impaired In this study, we aimed to...
Abstract Background In the PARADIGM-HF trial, sacubitril/valsartan (SV) was shown to be superior enalapril in reducing hospitalizations for worsening heart failure (HF), cardiovascular mortality, and all-cause mortality patients with reduced ejection fraction (HFrEF). The 2021 ESC Guidelines recommends SV as a replacement angiotensin-converting-enzyme inhibitors reduce risk of HF hospitalization death. There is little information regarding effects according atrial fibrillation (AF) status....
Abstract Collateral development in chronic total occlusions (CTO) is crucial to perfuse the distal myocardium and its angiographic evaluation frequently used assess need for revascularization. We aimed analyse association between presence of ischemia hibernating myocardium, evaluated by cardiac [ 13 N]NH3/2-[ 18 F]FDG PET-CT, characterization collateral circulation. Prospective study including patients with a CTO who underwent N]NH3 and, when deemed necessary, 2-[ PET-CT. Well developed (WD)...
Abstract Background Covid-19 is associated with an increased risk of pulmonary embolism (PE) therefore, should the cut off d-dimer value be adjusted for these patients? Material and methods Retrospective observational study to understand if there a cut-off that could guide clinics perform thoracic computed tomography angiography (CTA) in patients covid-19. The population was covid-19 admitted dedicated wards University Hospital Centre one year. Results conclusions 725 (52%) had dosed during...
Abstract Background Cardiopulmonary exercise testing (CPET) has an important role in mortality prediction heart failure (HF) and patient selection for transplant. New indices as circulatory power (CP) ventilatory (VP) have been proposed predictors of cardiac events. In addition, VP predicts mean pulmonary artery pressure (mPAP) patients with arterial hypertension. Purpose We aimed to analyse the prognostic value classic new CPET variables HF. Methods retrospectively assessed consecutive HF...
Abstract Introduction Cardiopulmonary exercise testing (CPET) is routinely used in the prognostic evaluation of patients with heart failure reduced ejection fraction (HFrEF). Left ventricular (LVEF) a strong marker but have shown bad correlation capacity. The aim this study to assess relationship between echocardiographic parameters and capacity HFrEF patients. Methods We retrospectively assessed all submitted CPET echocardiography March September 2019. 73 were eligible for analysis. ANOVA...
