Given that high and intermediate-high risk PE patients require special attention, a standardized procedure is provided to these patients by an established pulmonary embolism response team (PERT) at the Inselspital in Bern. The pulmonary embolism response team consists of an angiologist, a cardiologist, an emergency physician, and a cardiac surgeon available 24 hours a day, and 7 days a week. Each patient is evaluated whether he/she is best treated by anticoagulation only or additional catheter-directed thrombolysis or surgical pulmonary embolectomy is indicated. Hereby, an already established standardized clinical algorithm is used to guide treatment procedures depending on the individual risk setting (Appendix 5).
