A model using echocardiography to predict the severity of aortic regurgitation in patients with congenital heart disease. Data is from investigators at Boston Children's Hospital.

Parasternal Vena Contracta:

Enter the vena contracta width in centimeters(cm), measured from the parasternal long axis; for multiple jets, enter as comma separated values, eg., "0.5,0.1,0.1"
