The right ventricular fractional area change is a two-dimensional measure of right ventricular global systolic function usually made on an echocardiogram. It is obtained from the apical four-chamber view and is calculated as
- RV- fractional area change = (end-diastolic area - end-systolic area) / end-diastolic area
The normal value in adults is considered >35%.
