1. Common Arterial Trunk with Interrupted Aortic Arch
Abstract Clinical data: Patient diagnosed with common arterial trunk, submitted to pulmonary artery banding in another center and lost to clinical follow-up. Referred to our center at four years old, extremely cyanotic. Chest radiography: Cardiomegaly; attenuated peripheral vascular markings. Electrocardiography: Right ventricular hypertrophy. Echocardiograp

2. Rare Association Between Atrioventricular Septal Defect and Partial Anomalous Pulmonary Venous Connection
Abstract Clinical data: Infant, 7 months, female, referred to our department at one month of age, suspecting of congenital heart disease for further investigation. Chest radiography: Demonstrates cardiomegaly and prominent pulmonary vascular markings. Electrocardiography: Shows right ventricular hypertrophy and left anterior fascicular block. Echocardiog

3. Echocardiographic Correlation between Right Ventricular Function and Left Atrial Volume
Resumo Fundamentos: A relação entre a disfunção diastólica do ventrículo esquerdo (DDVE), seus achados mais importantes, como aumento do átrio esquerdo e hipertrofia ventricular esquerda (HVE), e a função do ventrículo direito (VD) tem pouca documentação na literatura científica. Objetivo: Avaliar a correlação entre o tamanho atrial esquerdo

4. Prevalence of electrocardiographic abnormalities in primary care patients according to sex and age group. A retrospective observational study
ABSTRACT BACKGROUND: Knowledge of the prevalence of electrocardiographic abnormalities in a population is useful for interpreting the findings. The aim here was to assess the prevalence of electrocardiographic abnormalities and self-reported comorbidities and cardiovascular risk factors according to sex and age group among Brazilian primary care patients.

5. Respiratory Muscle Training Improves Diaphragm Citrate Synthase Activity and Hemodynamic Function in Rats with Heart Failure
Abstract INTRODUCTION: Enhanced respiratory muscle strength in patients with heart failure positively alters the clinical trajectory of heart failure. In an experimental model, respiratory muscle training in rats with heart failure has been shown to improve cardiopulmonary function through mechanisms yet to be entirely elucidated. OBJECTIVE: The present r

6. Avaliação experimental do metabolismo energético em dois protocolos de sobrecarga sistólica do ventrículo direito / Experimental evaluation of energy metabolism in two right ventricle systolic overload protocols
Objective: Altered energy metabolism has been identified in myocardial hypertrophy. Some processes are considered beneficial, whereas others are linked to heart failure. The purpose of this study was to compare the activity of three different energy metabolism enzymes in two different protocols of right ventricle (RV) systolic overload in young goats. Method

7. Análise da função ventricular direita em dois protocolos de treinamento com bandagem ajustável do tronco pulmonar / Assessment of right ventricular function in two training protocols with adjustable pulmonary banding
The ideal surgical treatment of transposition of the great arteries is the Jatene operation during the neonatal period. If the neonate remains untreated for several reasons, the left ventricle may become unprepared to sustain systemic circulation. The preparation of the subpulmonary ventricle by pulmonary trunk (PT) banding is an option for the 2-stage Jaten

8. Influência da integridade dos barorreceptores nos ajustes morfofuncionais cardíacos à hipertensão espontânea em ratos / Influence of baroreceptor integrity on cardiac morpho-functional adjustments to spontaneous hypertension in rats
It has been demonstrated that reduced baroreflex sensitivity is an independent marker of mortality risk. The arterial baroreflex plays an important role in the maintenance of the moment-to-moment stability of blood pressure (BP). Although the contribution of blood pressure variability (BPV) to cardiovascular morbidity and mortality is well established, the m

9. Alterações cardiovasculares de fêmeas de ratos espontaneamente hipertensos (SHR) relacionadas com a idade / Cardiovascular changes in female spontaneously hypertensive rats (SHR) age-related
Hypertension is a major cause of cardiovascular disorders, and the natural progression of this disease may trigger further changes in the circulatory system. Experimental models are widely used in studies on the changes that occur in the cardiovascular system induced by hypertension. The SHR is the model that most closely matches the human hypertension, as i

10. Adaptação oxidativa e funcional progressiva do sistema cardiopulmonar secundária à hipertensão arterial pulmonar em ratos
Pulmonary Arterial Hypertension (PAH) is a disease that affects the pulmonary vessels, essentially pre-capillaries, leading to remodeling of the vascular wall. It is characterized hemodynamic syndrome, which is the increase in pulmonary vascular resistance and right ventricular afterload. A growing body of evidence shows the involvement of oxidative stress i

11. A influência do estrogênio na hipertensão arterial pulmonar : papel do estresse oxidativo
A hipertensão arterial pulmonar é uma síndrome caracterizada por vasoconstrição e remodelamento vascular pulmonar, levando a um aumento progressivo na resistência vascular pulmonar, que eleva a pós-carga imposta ao ventrículo direito, gerando consequente hipertrofia e insuficiência cardíaca direita. Essa doença acomete duas vezes mais mulheres do

12. Efeito protetivo da hipertrofia ventricular esquerda nas oclusoes de coronaria direita / Protective effect of left ventricular hypertrophy in right coronary artery occlusions
Objective - To test the hypothesis that left ventricular hypertrophy (LVH) reduces the electrocardiographic and functional effects of right coronary artery occlusion. Methods - We analysed 215 patients (166 males and 49 women,age of 58.9±10.6 years), with occlusion of the right coronary artery without other associated lesions. There was no significant diffe
