Infants with aortic valve stenosis go to the pediatric cath lab for balloon dilation of the valve.
The balloons are small, shaped like a hotdog, are positioned across the stenotic valve then quickly inflated and deflated to open the valve. A second procedure we do for kids is called the "ross procedure" where a patient's pulmonary valve
is moved to the aortic and a graft
replaces the pulm valve.
