Treatment of choice in a patient of acute pulmonary embolism with right ventricular hypokinesis and compromised cardiac output but normal blood pressure is:

Successful fibrinolytic therapy rapidly reverses right hea failure. Thrombolytic therapy in pulmonary embolism is used for patients who present with hemodynamic compromise, patients who develop hemodynamic compromise during conventional therapy with heparin, and patients with embolism associated with intracavitary right-hea thrombi. Acute embolectomy might be considered in patients with hemodynamically massive PE or right-hea thrombus who have an absolute contraindication to anticoagulant or thrombolytic therapy.
