Successful intraprocedural anticoagulation with bivalirudin during pulmonary vein isolation in a patient with known heparin-induced thrombocytopenia type II

چکیده
We report the case of a 56-year-old female who presented with symptomatic paroxysmal atrial fibrillation. Anamnestic heparin-induced thrombocytopenia (HIT) type II was suspected, and a rapid diagnostic test showed antibodies against platelet factor 4. The heparin-induced platelet activation-assay was negative. Radiofrequency pulmonary vein isolation with intraprocedural anticoagulation using bivalirudin was ultimately performed. Dosing was controlled by monitoring the activated clotting time. Post-procedural blood tests were normal. There were no thromboembolic or bleeding events. Bivalirudin is a therapeutic option for anticoagulation during pulmonary vein isolation procedures in patients with a history of HIT type II.

Current guidelines recommend using bivalirudin as an alternative to unfractionated heparin in patients with heparin-induced thrombocytopenia undergoing percutaneous coronary intervention (PCI). Pulmonary vein isolation (PVI) is a well-established treatment strategy for patients with drug-refractory atrial fibrillation (AF) and requires systemic anticoagulation to avoid thromboembolic events, ge...

Type II heparin-induced thrombocytopenia (HIT) is an immune-mediated syndrome that may arise in a time-dependent manner following heparin therapy, placing patients at significant risk for thromboembolic events. Therapy includes anticoagulation with a direct thrombin inhibitor and avoidance of heparin. We report a patient with Budd-Chiari syndrome and a history of heparin-induced thrombocytopeni...

Heparin-induced thrombocytopenia (HIT) is an antibody-mediated reaction in which heparin administration causes a person to enter a pathological and highly prothrombotic state. When patients with known HIT undergo coronary artery bypass and grafting procedures, they must be appropriately anticoagulated. The dangers of heparin administration in this population necessitate the use of an alternativ...

Heparin-induced thrombocytopenia presents a challenge for anticoagulation techniques during cardiac surgery and ventricular assist device implantation. Bivalirudin is currently recommended for use during cardiopulmonary bypass for patients with heparin-induced thrombocytopenia but requires the use of special techniques to avoid blood stagnation. We report the successful use of bivalirudin durin...

Heparin-induced thrombocytopenia (HIT) is a problem of growing significance and concern, affecting an estimated 1-3% of patients among those receiving an estimated 10 million heparin exposures annually in the United States. The prevalence of heparin antibodies has been reported as at least 12.7% in the general cardiac surgery population before surgery and 42% following surgery. Various manageme...
