1. Pulmonary Thromboendarterectomy Without Circulatory Arrest
Abstract Introduction: Here we describe our technique and results of beating heart pulmonary thromboendarterectomy (PTE) with cardiopulmonary bypass (CPB) in four patients for treatment of chronic thromboembolic pulmonary hypertension (CTEPH). Methods: Retrospective analysis of data from patients who underwent PTE for CTEPH between January 2019 and Septemb

2. The Predictive Effects of Clinical Hematological Changes on Saphenous Graft Patency after Coronary Artery Surgery
Abstract Objectives: To investigate the association between clinical hematologic parameters and saphenous vein graft failure after on-pump coronary artery bypass surgery. Methods: A total of 1950 consecutive patients underwent isolated on-pump coronary artery surgery between November 2010 and February 2013. Of these, 284 patients met our inclusion criteria

3. Common operation, uncommon complication. Bleeding from superior haemorrhoidal artery after minimally invasive procedure for hemorrhoids - a case report
RESUMO O procedimento minimamente invasivo para as hemorroidas (PMIH) é uma das novas operações mais comuns para ao tratamento de hemorroidas prolapsadas. O diâmetro do tecido grampeado é crítico nessa operação; um aumento nesse diâmetro poderia colocar mais tecido na bigorna do grampeador, com resultados desastrosos. Este relato de caso descreve o

4. Anterior Spinal Artery Syndrome Following Coronary Artery Bypass Grafting: a Case Report
Abstract We present a patient with unstable angina candidate for coronary artery bypass grafting. Saphenous vein graft was used in obtuse marginal and left internal mammary artery to left anterior descending artery properly. After surgery, the patient experienced flaccid paralysis of lower limb and impaired sensation of touch and warmth of knee and below. A

5. B-type natriuretic peptide as a predictor of anterior wall location in patients with non-ST-elevation myocardial infarction
OBJECTIVE: Involvement of the left ventricular anterior wall in ST-elevation myocardial infarction has a worse prognosis compared with other regions. In non-ST-elevation myocardial infarction, noninvasive methods of locating the ischemic myocardial territory have been limited. The objective of this report is therefore to determine what factors are predictive

6. Quantitative evaluation of experimental choroidal neovascularization by confocal scanning laser ophthalmoscopy: fluorescein angiogram parallels heparan sulfate proteoglycan expression
The objective of the present study was to develop a quantitative method to evaluate laser-induced choroidal neovascularization (CNV) in a rat model using Heidelberg Retina Angiograph 2 (HRA2) imaging. The expression of two heparan sulfate proteoglycans (HSPG) related to inflammation and angiogenesis was also investigated. CNV lesions were induced with argon

7. Predictors of restenosis after percutaneous coronary intervention using bare-metal stents: a comparison between patients with and without dysglycemia
The objective of this study was to identify intravascular ultrasound (IVUS), angiographic and metabolic parameters related to restenosis in patients with dysglycemia. Seventy consecutive patients (77 lesions) selected according to inclusion and exclusion criteria were evaluated by the oral glucose tolerance test and the determination of insulinemia after a s

8. Frequencia de aterosclerose nas arterias radiais de 29 cadaveres / Frequency of atherosclerosis in radial arteries of 29 cadavers
The use of radial artery as a coronary artery bypass graft increased since 1992. It is justified that arterial grafts theoretically would last more than venous grafts. But radial arteries could have atherosclerotic obstructions before cardiac bypass grafting surgery. The objective of this study is to verify the incidence of atherosclerotic obstructions and m

9. Progressão da aterosclerose coronária avaliada pela coronariografia, em portadores de doença multiarterial submetidos a tratamento clínico, cirúrgico ou angioplastia / The progression of atherosclerotic coronary disease assessed by coronary arteriography in patients with multivessel coronary disease undergoing medicine, angioplasty, or surgery treatments
Introdução: Freqüentemente a progressão da doença coronariana aterosclerótica é observada por angiogramas seqüenciais e atribuída ao aumento da incidência de eventos coronarianos.O significado prognóstico desta progressão em pacientes randomizados e submetidos a diferentes formas terapêuticas ainda é pouco conhecido. Este estudo compara a progr

10. Influence of routine assessment of fractional flow reserve on decision making during coronary interventions / Influência da avaliação rotineira do fluxo fracionado de reserva durante intervenções coronárias percutâneas na estratégia terapêutica
BACKGROUND: In complex and multivessel coronary artery disease, it is often difficult to assess which lesions are associated with reversible ischemia and should be stented. Fractional flow reserve (FFR) is a well established methodology to indicate which lesions are culprit or not. Yet, frequently the selection of lesions to be stented is based on the angiog

11. Relação entre a proliferação neointimal e a lesão inicial, em pacientes portadores de stent coronario, pela angiografia quantitativa
In the process of restenosis, neointimal proliferation appears to be associated with initial plaque, according to intravascular ultrasound studies. The purpose this study was to assess the relationship between initial plaque and neointimal proliferation afier stent implantation using quantitative coronary angiography (QCA). Methods: We select the data fi:om

12. Effect of stenosed and occluded coronary arteries on immediate and late myocardial uptake of thallium-201.
Exercise and redistribution myocardial scintigraphy using thallium-201 was compared with the left ventricular angiogram and with the presence of stenosis or occlusion of coronary arteries on angiography. Irreversible scintigraphic defects representing areas of myocardial infarction were found in all patients with occlusion of the left anterior descending art
