Pulmonary Capillary Wedge Pressure (PCWP) by E/e'

– share this tool –

Data Acquisition

Diastolic function measurement

Reference Values

PCWP (mmHg)
Normal 2-15
Increased filling pressure >15


\[E’ = \frac{E’_{lateral} + E’_{septal}}{2}\]

\[PCWP = 1.24(E/E’) + 1.9\]


E Mitral inflow E velocity
E’ lateral Early diastolic velocity of lateral mitral annulus
E’ septal Early diastolic velocity of septal mitral annulus
PCWP Mean pulmonary capillary wedge pressure
