RV dysfunction = mortality Goldhaber. Lancet. 1999; 353:1386-89. AHA Categorization of PE • LowRisk: Sub- massive PE Massive PE No right ventricular (RV) strain or hemodynamic instability. • Favorable prognosis • 30-50% of PE patients. • 3-21% mortality • “hemodynamically stable” with RV strain • 5% of PE patients. • 90-day mortality rate 50%. • Hemodynamically unstable Definitions • Massive PE - Acute PE with sustained hypotension (SBP < 90mmHg for at least 15 minutes or requiring inotropic support and not due to a cause other than PE) • Submassive PE - Acute PE without systemic hypotension but with either RV dysfunction or myocardial necrosis RV dysfunction: RV dilatation (RV/LV diameter > 0.9) RV dysfunction on ECHO RV dilatation on CT Elevated BNP (>90pg/mL) Elevation of N-terminal pro-BNP (>500pg/mL) ECG changes (new complete or incomplete RBBB, anteroseptal STE or ST-dep, anteroseptal TWI) Myocardial necrosis Elevated troponin I (> 0.4 ng/mL) Elevated troponin T (>0.1 ng/mL) • Low Risk JaffMR.Circula.on2011;123:1788-830. Catheter Embolectomy/Fragmentation or Surgical Embolectomy for PE • Depending on local expertise - Massive PE and contraindications to fibrinolysis (Class IIa; Level of Evidence C). • Massive PE who remain unstable after receiving fibrinolysis (Class IIa; Level of Evidence C). • Massive PE and contraindications to fibrinolysis or unstable after fibrinolysis, transfer to an institution experienced in either catheter embolectomy or surgical embolectomy (Class IIa; Level of Evidence C). • Submassive acute PE with clinical evidence of adverse prognosis (new hemodynamic instability, worsening respiratory failure, severe RV dysfunction, or major myocardial necrosis) (Class IIb; Level of Evidence C). • Not recommended for low-risk PE or submassive acute PE with minor RV dysfunction, minor myocardial necrosis, and no clinical worsening (Class III; Level of Evidence C). JaffMR.Circula.on2011;123:1788-830. Fibrinolysis for acute PE 1. Massive acute PE and acceptable risk of bleeding complications (Class IIa; Level of Evidence B). 2. Submassive acute PE with adverse prognosis (new hemodynamic instability, worsening respiratory insufficiency, severe RV dysfunction, or major myocardial necrosis) and low risk of bleeding complications (Class IIb; Level of Evidence C). 3. Not recommended for low-risk PE (Class III; Level of Evidence B) or submassive acute PE with minor RV dysfunction, minor myocardial necrosis, and no clinical worsening (Class III; Level of Evidence B). 4. Not recommended for undifferentiated cardiac arrest (Class III; Level of Evidence B). JaffMR.Circula.on2011;123:1788-830.

Contemporary data and technology may suggest utilizing therapies beyond anticoagulation. In the absence of large, controlled studies, a team approach should be utilized. THANK YOU
