Massive Pulmonary embolism
In the past, "massive pulmonary embolism" has been defined on the basis of angiographic burden of emboli by using the Miller Index[1]. This is a retrospective diagnosis based upon the pulmonary angiogram that does not inform prospective decisions.
Recently American heart association[2] has proposed the following definition for Massive PE: Acute pulmonary embolism with sustained hypotension (systolic blood pressure <90 mm Hg for at least 15 minutes or requiring inotropic support, not due to a cause other than PE, such as arrhythmia, hypovolemia, sepsis, or left ventricular [LV] dysfunction), pulselessness, or persistent profound bradycardia (heart rate <40 bpm with signs or symptoms of shock).
