Pharmacotherapy

Current guidelines recommend using bivalirudin, a direct thrombin inhibitor,as a preferred alternative to unfractionated heparin in patients with heparin induced thrombocytopenia (HIT) for percutaneous coronary intervention, as well as for cardiac and vascular surgery. Anticoagulation during radiofrequency catheter ablation (RFA) procedures may be another potential use for bivalirudin in the setting of HIT. Radiofrequency catheter ablation procedures involving left atrial or left ventricular access are increasingly employed as a method to treat cardiac arrhythmias. ⋯ Both procedures were completed without any embolic events. No bleeding or clotting events were noted; one patient experienced minor access site oozing that was not felt to be clinically important. Bivalirudin is a therapeutic option for anticoagulation during left-sided catheter RFA procedures in patients with a history of HIT.
