Tirofiban in Suspected Left Ventricular Assist Device Pump Thrombosis.

Antithrombotic optimization with a glycoprotein IIb/IIIa inhibitor has been used for the treatment of suspected pump thrombosis, but available literature with tirofiban is lacking. This study aims to describe the use of tirofiban for suspected pump thrombosis. This was a single-center cohort study of left ventricular assist device patients who received tirofiban for the treatment of suspected pump thrombosis from January 1, 2016 to July 31, 2017.

Risk Factors and Outcomes Associated with Prolonged Subtherapeutic Anticoagulation with Bivalirudin: A Retrospective Cohort Study.

Background: Bivalirudin, a direct thrombin inhibitor, is a treatment option for the management of heparin-induced thrombocytopenia (HIT) and other coagulation disorders. To date, no published studies have identified patients at risk for or the consequence of subtherapeutic bivalirudin therapy.

Objectives: The primary objective was to identify factors associated with failure to achieve early therapeutic anticoagulation (ETA) with bivalirudin, defined as achievement of two consecutive therapeutic activated partial thromboplastin times (aPTTs) within 24 hours.
