The effect of increasing the amount of vascular obstruction on mean PAP (mmHg) shown for 5, 7, and 10 mm emboli. Pulmonary hypertension (PH) is defined clinically as PAP >25 mmHg,and right ventricular failure (RVF) is considered likely at pressures >40 mmHg. ;(1).Gali N,Hoeper MM,Humbert M,Torbicki A,Vachiery J-L,Barbera JA,Beghetti M,Corris P,Gaine S,Gibbs SJ, et al.Guidelines for the diagnosis & treatment of PH: the Task Force for the Diagnosis and Treatment of PH of the European Society of Cardiology & the European Respiratory Society, endorsed by the International Society of Heart Lung Transplantation.Eur Heart J. 2009 ;30(20):2493-537. ; (2).McIntyre KM,Sasahara AA.Hemodynamic alterations related to extent of lung scan perfusion defect in pulmonary embolism.J Nucl Med. 1971 ;12(4):166-70. ;; (3).Knapp RS,Mullins CB.Progressive tricuspid regurgitation as a limit to right ventricular output in acute pulmonary hypertension.
