Assessment of Anticoagulation in Patients Receiving Ultrasound-Assisted Catheter-Directed Thrombolysis for Treatment of Pulmonary Embolism.

Background: Ultrasound-assisted, catheter-directed thrombolysis (USAT) has emerged as a popular treatment option for submassive pulmonary embolism (PE). The optimal strategy for transitioning patients from full-intensity to reduced-intensity heparin during the procedure has yet to be established.

Objective: The goal of this study was to evaluate the anticoagulation management in patients receiving catheter-directed thrombolysis with USAT.
