Biventricular Echocardiographic Index of Goda et al for Predicting Survival of a Patient with Pulmonary Hypertension

Description

Goda et al developed simple echocardiographic index based on the ratio of ventricular areas in patients with pulmonary hypertension. The ratio is a measure of cardiac remodeling and can identify a patient who may benefit from more aggressive management. The authors are from the University of Pittsburgh.


Patient selection: pulmonary hypertension

 

Imaging study: apical 4-chamber view (giving a longitudinal view of the ventricular cavities)

 

Parameters:

(1) end-diastolic area for the right ventricle in square centimeters

(2) end-diastolic area of the left ventricle in square centimeters

 

ratio of right to left ventricular areas =

= (right ventricular area) / (left ventricular area)

 

Interpretation:

• A ratio >=0.93 was associated with increased all-cause mortality (odds ratio 1.8) in multivariate analysis.

• Other risk factors for mortality: older age; right ventricular global strain >= (-15%).
