    Abstract:
    Acute pulmonary embolism (PE) causes significant morbidity and mortality, particularly for patients with subsequent right ventricular (RV) dysfunction. Once diagnosed, risk stratification is imperative for therapeutic decision making and centers on evaluation of RV function. Treatment includes supportive care, systemic anticoagulation, and consideration of reperfusion therapy. In addition to systemic anticoagulation, patients with high-risk PE should receive reperfusion therapy, typically with systemic thrombolysis. The role of reperfusion therapies, which include catheter-based interventions, systemic thrombolysis, and surgical embolectomy, are controversial in the management of intermediate risk PE. Catheter directed thrombolysis (CDT) can be considered in certain intermediate risk patients although prospective, comparative data for its use are lacking. Surgical or catheter embolectomy are viable treatment options for high-risk patients in whom reperfusion therapy is warranted but who have absolute contraindications to thrombolysis. Further research is needed to better elucidate which patients with PE would most benefit from advanced reperfusion therapies.
