Am Heart J. Commentary on: Eikelboom JW, Connolly SJ, Brueckmann M, et al. [25,26] In a randomized controlled trial comparing warfarin with the direct oral thrombin-inhibitor dabigatran for the prevention of thromboembolic events in patients with mechanical heart valves, the treatment with dabigatran was associated with an increased risk of thromboembolic and bleeding events however. The RE-ALIGN investigators concluded that at the doses studied, dabigatran was less effective than warfarin for thromboembolic prevention in patients with mechanical heart valves and was associated with an increased risk of bleeding; therefore, dabigatran should not be used in patients with mechanical heart valves. 2013; 369 : 1206-1214 View in Article Dabigatran versus warfarin in patients with mechanical heart valves.

BACKGROUND: Dabigatran is an oral direct thrombin inhibitor that has been shown to be an effective alternative to warfarin in patients with atrial fibrillation. The addition of aspirin 75 to 100 mg once daily to therapeutic warfarin is recommended for all patients with mechanical heart valves and those patients with biological valves who have risk factors.

BACKGROUND: Dabigatran is an oral direct thrombin inhibitor that has been shown to be an effective alternative to warfarin in patients with atrial fibrillation. Thousands of people take this class of drugs for clot prevention with atrial fibrillation.

Dabigatran versus warfarin in patients with mechanical heart valves. 2013 Sep 26;369(13):1206-14. Extended Use of Dabigatran, Warfarin, or Placebo in Venous Thromboembolism. Waltham, MA: Massachusetts Medical Society. Mechanical heart valves: Dabigatran is contraindicated in patients with mechanical heart valves. Methods. Most of the evidence for using aspirin in combination with a vitamin K antagonist for patients with mechanical heart valves comes from small studies of low quality. Only one study has been released on dabigatran versus warfarin in people with mechanical heart valves. Methods In patients with mechanical heart valves, anticoagulation with dabigatran was associated with significantly higher rates of stroke and major bleeding when compared to warfarin. The decision between initiating dabigatran or warfarin is influenced by indication and the patientâs characteristics, e.g. Only one study has been released on dabigatran versus warfarin in people with mechanical heart valves. A randomised controlled trial that compared 84 patients on warfarin and 168 patients on dabigatran who had a recent mechanical heart valve replacement, was stopped early at 12 weeks because of safety concerns. BACKGROUND: Dabigatran is an oral direct thrombin inhibitor that has been shown to be an effective alternative to warfarin in patients with atrial fibrillation. 2 Connolly SJ, et al. Patients who received mechanical heart valves (MHVs) have significantly lower mortality, higher cumulative incidence of bleeding and, in some age groups, stroke than recipients of a biologic prosthesis .

Patients aged â¥18 years and â¤75 years, either undergoing implantation of a mechanical bileaflet valve (aortic or mitral or both) during the current hospital stay or having undergone implantation a mitral bileaflet valve >3 months before randomization, will be randomized between dabigatran etexilate or warfarin (in a ratio of 2:1) in an open-label design.
