Background: Catheter-directed thrombolysis (CDT) is one of the emerging venous thromboembolism management modalities. There are fairly limited data regarding the use of direct-thrombin inhibitors (DTIs) in patients with heparin-induced thrombocytopenia and undergoing CDT.
Objectives: The aim of this study was to provide a summary of the available evidence supporting the use of DTIs in patients undergoing CDT.
Methods And Results: We included 6 case reports in our analysis after searching for peer-reviewed articles and case reports in multiple research engines. Four of the 6 cases used argatroban, and 2 cases used bivalirudin. Alteplase was used in all of the 6 cases. All cases used lower activated partial thromboplastin time target. The average initial dose of alteplase ranged from 0.5 to 3 mg/h. The average duration of CDT was 26 hours (SD, 13 hours). Five patients (83%) survived after the procedure, and no complications were reported.
Conclusions: The use of DTIs might be safe and effective in selected patients with heparin-induced thrombocytopenia and undergoing CDT.

Background: Heparin-induced thrombocytopenia (HIT) is a potentially life-threatening adverse drug reaction with numerous diagnostic challenges. Diagnosis of HIT begins with 4T score clinical assessment, followed by laboratory testing for those not deemed low risk. Laboratory testing for HIT includes screening [enzyme-linked immunosorbent assay (ELISA)] and confirmatory [serotonin release assay (SRA)] assays, wherein SRA testing can be pursued following a positive ELISA result.

Though there are models for use of non-heparin anticoagulants, heparin remains the preferred anticoagulant in many operative settings, especially cardiovascular surgery and percutaneous cardiac intervention. The natural history of HIT can be stereotyped into phases using HIT laboratory testing to guide clinical management and determine whether heparin re-exposure can be considered.

Background: IgG antibodies (Abs) to platelet factor 4 complexed to heparin (PF4/H) commonly occur after heparin exposure but cause life-threatening complications of heparin-induced thrombocytopenia (HIT) in only a few patients. Presently, only platelet activation assays reliably distinguish anti-PF4/H Abs that cause disease (HIT Abs) from those likely to be asymptomatic (AAbs).
Objectives: Recent studies indicate that complement activation is an important serologic property of HIT Abs and is essential for FcγRIIA-mediated cellular activation.

A 66-year-old man presented with chills, exertional dyspnea, and palpitations; he later developed a fever. Because of his elevated cardiac enzymes and electrocardiography and coronary angiography findings, he was diagnosed with acute myocarditis. Given his unstable hemodynamics, an intra-aortic balloon pump was inserted; however, he experienced a hemodynamic collapse due to refractory ventricular fibrillation.
