Is this pulmonic or subpulmonic stenosis?

There is severe right ventricular hypertrophy, asymmetric hypertrophy of the RV free wall-RVOT region causing significant sub pulmonic stenosis (infundibular pulmonic stenosis). There is no right ventricular dilatation. There is no tricuspid regurgitation. The free wall of the right ventricle measures 9 mm, normally it is less than 4 mm. In the sub infundibular region it is thickened to 15 mm. The right ventricular mass is between 70 to 95 g.
There is dephasing seen across the RVOT from the sub-pulmonic stenosis. However phase contrast and delayed post contrastwas not completed due to patient noncooperation. There is post stenotic dilatation of the main pulmonary artery.
