Endoscopic third ventriculostomy in patients with myelomeningocele after shunt failure.

Purpose: Myelomeningocele (MMC) is the most frequent form of spina bifida. Moreover, 90% of patients with MMC have hydrocephalus and require shunt placement. However, shunt failure management in such patients typically involves several shunt revisions, increasing the risk for morbidity and mortality.

Thromboembolism and bleeding risk scores and predictors of cardiac death in a population with atrial fibrillation.

Background: Atrial fibrillation (AF) is a common arrhythmia, with risk of systemic embolism and death. It presents rheumatic etiology in up to 32% of developing countries, whose anticoagulation and evolution data are scarce.

Objectives: to determine the predictors of cardiac death considering the clinical profile, thromboembolism and bleeding scores of patients with AF of a single center, with high prevalence of rheumatic heart disease.
