Thoughtful preparation with detailed input from the patient's comprehensive hemophilia center combined with vigilant pericatheterization hematologic management allowed for safe and successful cryoablation of this arrhythmia. Strategies for the management of patients with bleeding disorders who require invasive cardiac catheterization or surgery are reviewed. © 2010 Lippincott Williams & Wilkins, Inc.
