Aortic Valve Reconstruction with Ozaki Neo-Cuspidization in Unicuspid Disease

Aortic valve reconstruction by neo-cuspidization using the Ozaki technique has shown excellent mid-term outcomes, possibly due to the highly standardized and reproducible technique. It is being used increasingly in children with aortic valve disease. There are specific anatomic characteristics in congenital aortic valves that require adaptations of the technique.

This video presents the technique for a pediatric patient with a unicuspid aortic valve reconstruction with neo-cuspidization (Ozaki).

After establishing cardiopulmonary bypass and arresting the heart, the aortic valve was exposed, inspected, and the leaflets removed. A new annulus and three commissures were created and marked with an Ozaki sizer. The leaflets were then marked and created using the template on treated autologous pericardium. The leaflets were sewn in place and neo-valve competence was ensured.

The Ozaki aortic valve neo-cuspidization technique can be applied in patients with congenital heart disease with unicuspid valves, with excellent early results.
