The pulmonary embolism response team team is a multidisciplinary team made up of cardiologist and pulmonologist specialized. They work together to treat pulmonary embolism and to determine the best treatment plan and achieve the best outcomes. Once catheter directed thrombolysis is chosen as a management course, the practitioners should counsel the patient regarding the risk and benefits of the procedure. A trained physician knowledgeable in the risk and benefits should have this discussion. The patient should give consent. An anesthesiologist should evaluate the patient to determine the need, mode, and safety of anesthetic delivery. An imaging specialist or structuralist may consult for further recommendations on the size and burden of pulmonary embolism. It is a level I recommendation to utilize this multidisciplinary approach. Studies have shown the pulmonary embolism response team team can reduce adverse events 25). A swift and early diagnosis followed by early treatment is the key to successful thrombolysis of pulmonary embolism.
Is thrombolysis a catheter directed thrombolysis?
Though thrombolysis is administered locally during catheter directed thrombolysis for pulmonary embolism, the thrombolysis disperses systemically.

What is plasminogen activator?
Tissue plasminogen activator (tPA) is a thrombolytic (i.e. , it breaks up blood clots) formed by aggregation of activated platelets into fibrin meshes by activating plasminogen. More specifically, it cleaves the zymogen plasminogen at its Arg561-Val562 peptide bond to form the serine protease, plasmin 1). Plasmin, an endogenous fibrinolytic enzyme, breaks the cross-links between fibrin molecules, which are the structural support of the blood clot, and its activity is extremely short-lived. This is because alpha 2-antiplasmin, an abundant inhibitor of plasmin, quickly inactivates it and restricts the action of plasmin to the vicinity of the clot.
