Trial Offers Little Support for Early Use of Radiofrequency Ablation in Atrial Fibrillation
Larry Husten, PHD
A new trial offers little support for early use of radiofrequency ablation (RFA) to treat atrial fibrillation (AF). Current guidelines state that RFA may be indicated in patients with symptomatic paroxysmal AF after antiarrhythmic drug therapy has failed. Although earlier hopes have been dashed that RFA would prove to be a cure for AF, some experts […]

New Trial Confirms Role for Dabigatran in Venous Thromboembolism
Larry Husten, PHD
A new study helps support a role for the new oral anticoagulant dabigatran (Pradaxa, Boehringer Ingelheim) in patients with venous thrombosis (VTE). The RE-COVER II trial, published online in Circulation, confirms the finding of the earlier and highly similar RE-COVER trial, published in the New England Journal of Medicine in 2009, that dabigatran is as safe and effective as warfarin for […]
