Abstract Background Atrial fibrillation (AF) is the most frequent arrhythmia, and its prevalence increases with age. The management of AF in the elderly is challenging, as it is normally associated with comorbidities and frailty. AF catheter ablation (CA) is a safe and superior alternative to antiarrhythmic drugs (AADs) for the maintenance of sinus rhythm. Objectives To evaluate the rate of complications associated with CA for AF across different age groups. Methods A retrospective analysis of 219 patients who underwent CA […]

Abstract Background Infective endocarditis (IE) is a disease with high morbimortality and an increasing incidence. With improved diagnosis and treatment, a number of epidemiological changes have been reported over time. Objectives We sought to describe the epidemiological profile, mortality predictors, and analysis of a possible microbiological transition in patients admitted to three tertiary centers in Brazil. Methods In this cross-sectional retrospective study, data from 211 patients with definite or probable IE were analyzed according to the modified Duke criteria between […]
