Deciding  which pulmonary embolism patient needs thrombolytics/catheter based intervention is a shared decision among emergency physicians, intensivists, interventionalists, hospitalists, and the patient/family.  This  article provides evidence to help guide this decision.  Keep in mind “The use of either CDL or catheter-based embolectomy in patients with intermediate-risk PE has, thus far, been correlated only with more rapid improvement of RV dysfunction than anticoagulation alone, not short- or long-term clinical or functional outcomes.”

"1. Massive (AHA) or high risk (ESC): Hypotension, defined as a systolic blood pressure <90 mm?Hg, a drop of >40 mm?Hg for at least 15 minutes (this latter criterion may be difficult to ascertain in some clinical circumstances), or need for vasopressor support, identifies these patients. They account for ?5% of hospitalized patients with PE and have an average mortality of ?30% within 1 month.

2.Submassive (AHA) or intermediate risk (ESC): RV strain without hypotension (see above) primarily identifies these patients. RV strain includes RV dysfunction on computed tomography pulmonary angiography or echocardiography (RV/left ventricular [LV] ratio >0.9)6,7 or RV injury and pressure overload detected by an increase in cardiac biomarkers such as troponins or brain natriuretic hormone.

3.Low risk (ESC and AHA): These patients do not meet criteria for submassive (AHA) or intermediate-risk (ESC) PE"
