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. Early reduction of pulmonary arterial hypertension in patients using a long-term mechanical ventricular assistance device: a cross-sectional study
ABSTRACT BACKGROUND: Severe pulmonary arterial hypertension (PAH) is a contraindication for heart transplantation (HT). It has been correlated with increased early and late mortality, mainly associated with right ventricular failure. Ventricular assistance devices (VADs) can promote reduction of intracardiac pressures and consequent reduction of PAH over th

3. Acute Kidney Injury after Heart Valve Surgery in Elderly Patients: any Risk Factors to Modify?
Abstract Introduction: Postoperative acute kidney injury contributes to longer hospital stays and increased costs related to cardiac surgery in the elderly. We analyse the influence of the patient’s age on risk factors for acute kidney injury after cardiac valve surgery. Methods: We evaluated the prevalence and risk factors for acute kidney injury in 939

4. Hypotension and Bradycardia Produced by Transthoracic Application of Low-Intensity Ultrasound Therapy in Hearts of Healthy Rats - A Preclinical Study
Abstract Objective: To investigate the cardiovascular effects produced by transthoracic application of low-intensity pulsed ultrasound therapy (LIPUST). Methods: Three-month-old male Wistar rats (± 300 g, N=16) were randomly allocated in two groups, namely SHAM (control group, faked procedures) and UST (animals treated with LIPUST). These animals, under a

5. Cannot Extubate a Newborn Patient after an Arterial Switch Operation? Check Major Aortopulmonary Collaterals!
Abstract The standard treatment of transposition of the great arteries is the arterial switch operation (ASO). Despite successful surgical correction, patients cannot tolerate extubation after the operation. Major aortopulmonary collaterals (MAPCAs) are one of the rare causes of prolonged mechanical ventilation due to significant hemodynamic effects. We repo

6. Hepatic Elastography in the Assessment of Heart Failure: Where We Came from and Where We Are Going
Abstract Background: Stress test is used to detect coronary artery disease (CAD). The QTc interval dispersion (dQTc) is an electrocardiographic index of ventricular repolarization heterogeneity. Some researchers have linked transient myocardial ischemia induced by physical exertion with increased heterogeneity of ventricular repolarization measured by dQTc.

8. Relationship between right atrium area and right ventricular ejection fraction on magnetic resonance imaging: comparison with other prognostic markers in patients with pulmonary arterial hypertension
Resumo Objetivo: Comparar a área do átrio direito (AD) e a fração de ejeção do ventrículo direito (FEVD) com outros marcadores prognósticos conhecidos em pacientes com hipertensão arterial pulmonar (HAP). Materiais e Métodos: Identificamos, retrospectivamente, 74 pacientes com diagnóstico de HAP por cateterismo cardíaco direito em um centro de

9. Nailfold capillaroscopy as a risk factor for pulmonary arterial hypertension in systemic lupus erythematosus patients
Abstract Background: Pulmonary arterial hypertension (PAH) is a rare and severe complication of systemic lupus erythematosus (SLE). This study aimed to evaluate clinical and laboratory risk factors associated with PAH in SLE patients. Methods: This was a retrospective case-control study in which patients with SLE with PAH (SLE-PAH) confirmed by right heart

10. Valvular Disorders in Carcinoid Heart Disease
Abstract Carcinoid heart disease is a rare but important cause of intrinsic right heart valve disorders leading to right heart failure. Occasionally, left-sided heart valves may also be involved. The characteristic cardiac pathological findings of carcinoid heart disease are endocardial thickening as a result of fibrous deposits on the endocardium. Echocardi

11. Hemodynamic changes with high infusion rates of lipid emulsion. Experimental study in swine
PURPOSE: To evaluate hemodynamic changes caused by sole intravenous infusion of lipid emulsion with doses recommended for treatment of drug-related toxicity. METHODS: Large White pigs underwent general anesthesia, tracheal intubation was performed, and mechanical ventilation was instituted. Hemodynamic variables were recorded using invasive blood pressure

12. Avaliação da função ventricular sistólica e diastólica pelo ecocardiograma transesofágico e da capacidade funcional em ratos espontaneamente hipertensos submetidos à desnervação sino-aórtica / Evaluation of the systolic and diastolic ventricular function by transesophageal echocardiogram and functional capacity in spontaneously hypertensive rats submitted to sinoaortic denervation
INTRODUÇÂO: Durante o desenvolvimento da hipertensão arterial sistêmica (HAS) ocorre a hiperatividade simpática, que está relacionada ao comprometimento dos sistemas baro e quimiorreflexo arteriais e disfunção ventricular esquerda (VE). Entretanto, a função ventricular direita (VD) tem sido pouco avaliada no contexto da HAS associada à desnervaç�
