Definition cont’d.
Medically, AMPE is defined as an occlusion of the PA that exceeds
50% of its cross sectional area, resulting in progressive
hemodynamic compromise.
Massive PE is also defined as the presence of persistent systemic
hypotension or cardiogenic shock and signs of right ventricular
dysfunction (RVD).
A sub-massive PE is defined as moderate to large clot, presence of
RVD, and normal arterial blood pressure.
