This episode is part 2 of the PE podcast where we will discuss risk stratification and treatment of PE.  It's important that we accurately quanitfy the amount of clot burden that the patient has to order the right treatment and admit them (or maybe even discharge them) to the right location.  We'll talk about how to classify massive, sub-massive, and "non-massive" PEs and how to treat them. We'll also briefly talk about emergning evidence for the expanding role of thrombolytics and outpatient treatment of PE.
