 Historically, pulmonary embolism occurs in about one to two of every thousand people annually. It carries with it significant morbidity and mortality. Pulmonary embolism is blood clot moving toward your heart and your lungs. That's the simplest way I can explain that. In the past five to ten years, we've really experienced a revolution in therapies that have been advanced for treatment of pulmonary embolism, many of which have demonstrated superior efficacy over simple anticoagulation. Now as a vascular surgeon, I can offer them options other than just blood thinners. The typical treatment for PE is blood thinners, but I can potentially go through minimally invasive route, either through the groin or through the arm, and try to suction the clot out. Therapies that are wielded by vascular surgery and catheter-based therapies, we have therapies that are wielded by cardiac surgeons and surgical open embolectomy. We have intensivists who are good at front-end resuscitation, and we've got heart failure specialists and pulmonary hypertension specialists who are ideal at managing these patients long-term. In the old model of pulmonary embolism therapy that we've been following for years, it would be up to, if you're an emergency medicine physician, you identify somebody with a pulmonary embolism. It would be up to you to call a hospitalist or call an intensivist to get the patient admitted. If you've got a vascular surgeon or interventional radiology who performs these interventions, to call them and see if they might be amenable to providing catheter-based therapy. If you have a cardiac surgery group that might be interested in doing thrombectomy, to call them and see if they would evaluate the patient. What we provide with the PERT team, and the advantage of the PERT team and the pulmonary embolism response team, is that we bring all of these players to the table and all of their skill sets to the table for your individual patient. It really becomes a one-phone call solution for a patient with a submassive or massive pulmonary embolism. After the acute phase that the surgical team has intervened or not, these patients normally are followed by primary doctors. In our area, in our team, these patients are followed by a specific vascular medicine doctor that is looking for the complications or sequela of pulmonary embolism or DVT. So, and because vascular medicine sees these patients almost every day, we are very familiar with the complication with the missed details that can save the life. I can see if the patients are in the right anti-coagulation and if they need any other therapies to prevent them to develop chronic pulmonary pulmonary hypertension.
