Thrombosis with heparin-induced thrombocytopenia during percutaneous coronary intervention

Thrombosis with heparin-induced thrombocytopenia during percutaneous coronary intervention refers to acute thromboembolic complications arising in cardiovascular patients who develop or have immune-mediated heparin-induced thrombocytopenia (HIT) while undergoing catheter-based revascularization This intense prothrombotic state interacts with procedure-related endothelial disruption and intracoronary instrumentation, significantly increasing the risk of acute coronary occlusion, stent thrombosis,...

Pathophysiologically, IgG antibodies form against platelet factor 4–heparin complexes, binding to platelet FcγRIIa receptors and provoking platelet activation, consumptive thrombocytopenia, and excessive thrombin generation

This intense prothrombotic state interacts with procedure-related endothelial disruption and intracoronary instrumentation, significantly increasing the risk of acute coronary occlusion, stent thrombosis, or systemic thromboembolism

Because standard heparin-based anticoagulation is strictly contraindicated, this specific procedural setting requires prompt non-heparin anticoagulation to avert ischemic vessel compromise and procedural failure
