#### Example :

Let us consider the problem with the value of the early diastolic velocity of the lateral mitral annulus as 4 , the value of the early diastolic velocity of the medial mitral annulus as 3 and the value of mitral inflow E velocity as 2. Find PCWP?

###### Solution:

We can calculate the Pulmonary Capillary Wedge Pressure (PCWP) using the given PCWP by E/e' (Nagueh Formula).

#### Formula:

e = (l + s) / 2
p = (1.24 x (E / e)) + 1.9
**Where,**
e = Average of the Lateral and Septal E Values
l = Early Diastolic Velocity of Lateral Mitral Annulus
s = Early Diastolic Velocity of Medial Mitral Annulus
E = Mitral Inflow E Velocity
p = Mean Pulmonary Capillary Wedge Pressure
Substituting the values in the formula,

Average of the Lateral and Septal E Values = (4 + 3) / 2;
Average of the Lateral and Septal E Values = 3.5

Mean Pulmonary Capillary Wedge Pressure = (1.24 x (4 / 3.5)) + 1.9;
Mean Pulmonary Capillary Wedge Pressure = 3.884

Therefore, the values of
**Average of the lateral and septal E is 3.5** and ** Mean Pulmonary Capillary Wedge Pressure is 3.884.**
