Coding Notes

This term should be used for congenital subaortic stenosis due to lesions such as deviation of the outlet septum (seen in coarctation of the aorta and interrupted aortic arch), or a restrictive ventricular septal defect (bulboventricular foramen) in single ventricle complexes. This term should not be used for subaortic stenosis due to a fibromuscular shelf or tunnel, as specific terms exist for these lesions. For subaortic stenosis due to an atrioventricular valve in the setting of normal ventriculo-arterial connections, the term ‘Congenital left ventricular outflow tract obstruction due to an atrioventricular valve’ should be used.
