This talk introduces the concept of a new generation of pulmonary embolism (PE). What was once considered a deadly disease process now carries a mortality rate of <3%, which may be driven by overtesting as well as overdiagnosis. This talk will explore this phenomenon and current evidence-based approaches to the evaluation and treatment of PEs.
