Stanford Echo: http://www.stanford.edu/group/ccm_echocardio/cgi-bin/mediawiki/index.php/Main_Page Pressure gradient (dP) (mmHg) = 4v2 (m/s) Mean PA pressure = 0.61 × PASP + 2
Stroke volume = VTILVOT x AreaLVOT
LAP = SBP - dPLA/LV (MR jet)
Pulmonary hypertension = High TR max velocity (≥ 2.6 m/s) or low PA acceleration time (<105) Pressure (chronic) overload = D-shaped septum in systole Volume overload = D-shaped septum in diastole
EF ≈ 20 + 44(aortic root displacement [cm]) (Acad EM 2013; 20:367-373)Reference limits and values and partition values of left ventricular function
Estimation of right atrial pressure from the inferior vena cava (spontaneously breathing)
Am J. Cardiol. 1990;66: 493-6 Estimation of CVP from the IVC (mechanically ventilated)Diastology:Lusitropy = myocardial relaxation
Increased with catecholamines
Decreased with extracellular calcium

Mitral Valve Inflow (MVI) Normal: E > A
Impaired Relaxation: E < A
Pseudonormal: E > A
Restrictive: E >> A
Mitral Annulus Tissue Doppler (TDI)
Normal: e' > a'
Normal: e' > 8
Nagueh-Formula: 1.9 + (1.24 x E/E') = PCWP
