1. Circumflex Coronary Artery Fistula Draining into Coronary Sinus
ABSTRACT Coronary artery fistula draining into the coronary sinus is a rare vascular malformation, and its diagnosis and clinical manifestations usually occur late. We describe the case of a 72-year-old female patient with dyspnea on exertion (New York Heart Association Class III) associated with palpitations. The transthoracic echocardiogram showed signific

2. Streptococcus gallolyticus Bacteremia Detected in Apheresis Platelets and Its Link to Colonic Neoplasms
Abstract Introduction Streptococcus gallolyticus belongs to theStreptococcus bovis complex, and it is a common bacterium colonizing the gastrointestinal tract. Its presence in the blood may suggest an underlying pathology such as a colonic neoplasm. We report herein a case of S. bovis bacteremia in an apheresis platelet donor, review similar cases in the li

3. Evaluation of Ventricular Remodeling and Prognosis in Patients with Aortic Stenosis Who Underwent Surgical or Percutaneous Transcatheter Aortic Valve Replacement
ABSTRACT Introduction: Aortic stenosis is the most common heart valve disease in the world, and patients that present with symptoms have a high mortality rate. Aortic valve replacement has the objective of promote left ventricular remodeling, reduce symptoms, and increase overall survival. The objective of this study is to evaluate reverse remodeling of the

4. Strain Magnitude Assessed at Rest and During Stress Echocardiography in Patients with Normal Coronary Flow Reserve
Abstract Background Coronary flow and myocardial contractile performance assessed by strain magnitude increase during a dobutamine stress echocardiogram (DSE). Normal coronary flow reserve (CFR) can be attained upon completion of a DSE at age-predicted maximum heart rate (HR) (HRmax = 220 - age)] or submaximal HR [(0.85) HRmax] or before completion (early

5. Prognosis of Heart Failure with Preserved Ejection Fraction in Primary Care by the H2FPEF Score
Abstract Background: Primary care physicians have difficulty dealing with patients who have HF with preserved LVEF(HFpEF). The prognosis of HFpEF is poor, and difficult to predict on primary care. Objective: The aim of the study is to apply the H2FPEF score to primary care patients and verify its power to assess the risk of death or hospitalization due to

6. Gasparyan Method of Total Autologous Reconstruction of the Aortic Valve
Abstract In this case report, I describe a new technique for total reconstruction of the aortic valve with autologous pericardium. The parameters of the cusps were calculated using very simple formulas after measurement of the aortic root intercommissural distances. Glutaraldehyde-treated pericardium was trimmed along the marked line, leaving 2 mm of tissue

7. Relevance of Animal Models and Echocardiogram for Hypertensive Disease Studies
RESUMO O trabalho propõe uma metodologia para estabelecer competências em um perfil do profissional da informação com a perspectiva de uma visão regional que favoreça a mobilidade e tenda a melhorar e se adaptar a contextos mutáveis. A metodologia toma a taxonomia de Bloom como um quadro conceitual e estabelece elementos a serem preenchidos: áreas de

8. Dobutamine-induced Takotsubo syndrome during stress echocardiogram – An unusual but potentially severe association
Resumo Introdução e objetivo: A Cardiomiopatia Arritmogênica do Ventrículo Direito (CAVD) é uma cardiomiopatia genética caracterizada por taquicardia ventricular potencialmente letal. Descrevemos um paciente com CAVD com Cardioversor Desfibrilador Implantável (CDI) submetido a anestesia geral para cirurgia de seio maxilar. Relato do caso: Paciente m

10. Correlação entre a deflexão intrinsecoide, classificação clínica e parâmetros ecocardiográficos em cães com degeneração mixomatosa valvar mitral
RESUMO A degeneração mixomatosa valvar mitral (DMVM) costuma ser diagnosticada pelo ecocardiograma, porém o eletrocardiograma (ECG) pode sugerir alterações específicas e auxiliar no diagnóstico e no tratamento. A deflexão intrinsecóide (DI) é uma medida simples do ECG, que representa o início da despolarização ventricular e pode indicar a presen

11. Correlação entre os achados radiográficos e ecocardiográficos sugestivos de aumento cardíaco em cães: 104 casos
RESUMO Radiografias torácicas e ecocardiogramas de 104 caninos foram avaliados e correlacionados quanto ao aumento das câmaras cardíacas. Os achados radiográficos foram correlacionados estatisticamente a fim de se estabelecer a acurácia do exame radiográfico na detecção do aumento cardíaco em comparação ao ecocardiográfico - padrão-ouro não inv

12. Propranolol inhibits myocardial infarction-induced brown adipose tissue D2 activation and maintains a low thyroid hormone state in rats
Considering the recognized role of thyroid hormones on the cardiovascular system during health and disease, we hypothesized that type 2 deiodinase (D2) activity, the main activation pathway of thyroxine (T4)-to-triiodothyronine (T3), could be an important site to modulate thyroid hormone status, which would then constitute a possible target for β-adrenergic
