Ultrasound accelerated catheter directed thrombolysis for pulmonary embolus and right heart thrombus secondary to transvenous pacing wires.

Acute pulmonary embolism is associated with a significant number of deaths each year, which are commonly attributed to deep venous thrombosis of the lower extremity. Pulmonary embolism due to right-sided cardiac thrombus associated with transvenous wires is a rare occurrence. Treatment considerations have been systemic anticoagulation with heparin or systemic thrombolytic therapy. A unique case of a patient with symptomatic PE and extensive atrial and ventricle thrombus formation associated with transvenous pacing wires treated with ultrasound accelerated catheter directed thrombolysis is presented.
