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. 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

3. 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

4. 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.

5. QT Interval Dispersion Behavior in Patients With and Without Obstructive Coronary Artery Disease Undergoing Exercise Test
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.

6. Monitorizacion del gasto cardiaco con ecocardiografia transtoracica y cateter de Swan Ganz. Estudio comparativo en pacientes en ventilacion mecanica con presión positiva espiratoria final elevada
ABSTRACT Objective: To compare cardiac output measurements by transthoracic echocardiography and a pulmonary artery catheter in mechanically ventilated patients with high positive end-expiratory pressure. To evaluate the effect of tricuspid regurgitation. Methods: Sixteen mechanically ventilated patients were studied. Cardiac output was measured by pulmona

7. Challenges in Diagnosis and Management of Spontaneous Coronary Artery Dissection in a Young Patient
Abstract Spontaneous coronary artery dissection (SCAD) is characterized by tear of the inner layer in the coronary artery, creating a false lumen between the inner and central layer. Its infrequent incidence often leads to delay in diagnosis posing challenges in management. There are currently no guidelines for the treatment of this condition. We describe an

8. Evaluation of Myocardial Perfusion by Computed Tomography - Principles, Technical Background and Recommendations
Resumo A angiografia coronariana por tomografia computadorizada (ACTC) assumiu um papel de destaque na avaliação da doença arterial coronariana. Entretanto, sua natureza anatômica não permitia a avaliação da repercussão funcional das obstruções coronarianas. Recentemente, tornou-se possível a avaliação da perfusão miocárdica por tomografia com

9. 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

10. Symptomatic Aortic Valve Mass - Cardiac Work-Up Challenges and Role of Computed Tomography Angiography: A Case Report
Abstract Cardiac papillary fibroelastoma are rare, benign cardiac tumors that may lead to lethal complications from embolization or valvular dysfunction if left untreated. When working up symptomatic tumors with concomitant angina, traditional diagnostic studies such as cardiac catheterization may predispose the patient to embolic complications if the mass i

11. Analysis of the Appropriate Use Criteria for Coronary Angiography in Two Cardiology Services of Southern Brazil
Resumo Fundamento: Apesar de sua grande relevância, não existem trabalhos em nosso país que avaliem a aplicação das diretrizes de 2012 para uso apropriado do cateterismo cardíaco diagnóstico. Objetivo: Analisar a apropriação das coronariografias realizadas em dois hospitais da região sul do Brasil. Métodos: Estudo transversal multicêntrico, qu

12. Fístula arteriovenosa pós-cateterismo radial com repercussões cardiopulmonares
Resumo O presente artigo relata o caso de um paciente coronariopata de 86 anos submetido a cateterismo cardíaco via acesso radial à esquerda. Cerca de 16 meses após o procedimento, manifestou dispneia sem relação com esforço, associada a hipóxia noturna. Apresentava frêmito à palpação do punho esquerdo e foi diagnosticado com fístula arterioveno
