OBJECTIVES The primary objectives of this study were to assess the feasibility of temperature-controlled radiofrequency catheter ablation of left and right sided manifest accessory pathways in patients with Wolff-Parkinson-White syndrome and to gain more insights into biophysical aspects of temperature-controlled catheter ablation in humans. BACKGROUND The electrode-tissue interface temperatu...

Rev Esp Cardiol 2003;56(4):331-2 331 Today the majority of tachyarrhythmias can be treated with percutaneous ablation.1 To summarize, the ablation procedure consists of transmitting energy (generally radiofrequency) to the distal electrode of a catheter introduced into the heart via a vein or artery. This electrode, once placed at the site chosen by means of electroanatomic references, selectiv...

We evaluated the presentation, treatment, and outcome of infants who present with ventricular tachycardia in the first year of life. Seventy-six infants were admitted to our institution with a diagnosis of ventricular tachycardia between January, 1987 and May, 2006. Forty-five infants were excluded from the study because of additional confounding diagnoses including accelerated idioventricular ...

BACKGROUND Urolithiasis is a common and recurrent disease, whose prevalence rate has recently increased in parallel to obesity pandemic. OBJECTIVES To estimate the prevalence of history of urolithiasis in a non-randomized sample of adults assisted by a community-based health program and to analyze its association with metabolic syndrome. METHODS Cross-sectional study set in Niteroi, Rio de ...

OBJECTIVE The aim of this study was to evaluate the value of lung ultrasound in the diagnosis of respiratory distress syndrome (RDS) in newborn infants. METHODS From March 2012 to May 2013, 100 newborn infants were divided into two groups: RDS group (50 cases) and control group (50 cases). According to the findings of chest x-ray, there were 10 cases of grade II RDS, 15 grade III cases, and 2...

Introduction Wolff-Parkinson-White (WPW) syndrome is characterized by a short PR interval, wide QRS complex, and paroxysmal supraventricular tachycardia. An accessory atrioventricular connection is known to be the underlying mechanism of this syndrome. Accessory pathways (APs) are mainly located along the tricuspid or mitral annulus, accounting for 10%– 20% and 50%–60% of cases, respectively. M...
