    • Moderate subpulmonary stenosis across a double chambered right ventricle

The subcostal short axis view is a excellent view to profile the right ventricular outflow tract and pulmonary valve. In cases of double chambered right ventricle, hypertrophied muscle bands can be visualized dividing the right ventricle into two chambers and causing right ventricular outflow tract obstruction. The severity of obstruction can be assessed from this view using color and spectral Doppler.
