Aortoventriculoplasty in a five-month-old infant: an alternative approach to the treatment of critical aortic stenosis in infancy.

A newborn with critical aortic stenosis and anular hypoplasia was treated with an aortic valvotomy using inflow occlusion. Five months later, important valvular insufficiency and residual stenosis necessitated aortic valve replacement. An aortoventriculoplasty using a 19 mm St. Jude Medical Valve was successfully performed with a good hemodynamic response.
