Revista Colombiana deCardiología CARDIOLOGÍA DEL ADULTO ---REVISIÓN DE TEMAS Guía basada en la evidencia para el manejo perioperatorio de la anticoagulación oral con warfarina en pacientes con alto riesgo embólico que serán llevados a implante de dispositivos de estimulación cardiaca bajo la licencia CC BY-NC-ND (http://creativecommons.org/licenses/by-nc-nd/4.0/). 28 A. Olaya et alResultados: Las guías SIGN y CHEST tuvieron la mejor calificación con AGREE II. Con la nueva evidencia disponible proveniente de tres revisiones sistemáticas y dos experimentos clínicos, se generó recomendación fuerte a favor de continuar la anticoagulación oral con warfarina durante el perioperatorio de implante de dispositivos de estimulación cardíaca en pacientes con riesgo embólico moderado y alto. Conclusiones: A partir de la nueva evidencia cambia la recomendación propuesta por las guías SIGN y CHEST. La alternativa de continuar la terapia con warfarina a cambio de realizar terapia puente, debe considerarse en la práctica clínica. Evidence-based guidelines for the perioperative management of oral anticoagulation with warfarin in patients scheduled for implantation of a cardiac electronic device AbstractIntroduction: The perioperative management of chronic anticoagulation concerns all physicians involved in the implantation of cardiac electronic devices (either pacemakers and cardioverterdefibrillators). Switching from warfarin to low molecular weight heparins (LMWH) has been performed to reduce the risk of bleeding. However, this approach has been shown to be controversial. Objective: To generate evidence-based recommendations on the perioperative management of oral anticoagulation with warfarin in patients who will undergo the implantation of a cardiac electronic device. Methods: A literature search was performed to identify evidence-based clinical practice guidelines, which were assessed using the AGREE II instrument. The guidelines were updated with systematic reviews and randomized clinical trials published from February 2009 to November 2013 comparing the continuation of warfarin versus switching to a LMWH or withholding warfarin. These studies were analyzed using the SIGN and GRADE scales to assess methodological quality. Recommendations were put forward through an expert panel. Results:The guidelines with highest methodological quality were the SIGN (Scottish Intercollegiate Guidelines Network) guideline published in June 2013 and the CHEST guideline published in February 2012. The update included three systematic reviews and two randomized clinical trials. The continuation of warfarin for the perioperative management of implantable cardiac electronic devices in patients with moderate and high risk is recommended. Conclusion: Based on the new evidence changes the recommendation given by the CHEST SIGN and guides. The alternative of continued therapy with warfarin in exchange for performing therapy bridge, should be considered in clinical practice.
