Abstract
We report a successful case in which the classical tricuspidalization technique Ozaki was used for bicuspid aortic valve (BAV) severe stenosis in 7-month-old-baby.
An infant was admitted for progressively worsening aortic stenosis due to a congenital BAV after non-successful neonatal balloon aortic valvuloplasty. Preoperative examination revealed peak transaortic valve gradient > 90 mm Hg. Surgery was performed with cardiopulmonary bypass via median sternotomy. The aortic valve was consisting of two cusps, and all leaflets were pretty thick, fused, and
dysplastic. As there was no any part of the leaflets that could work as a valve, so it was assumed to be non-repairable. Given to diminutive aortic annulus diameter (10 mm), the new cusps measured size 13 mm was created from the adapted for pediatric patients’ small template using autopericardium.
The neocuspidalization of the aortic valve with classical Ozaki technique can be accomplished with an acceptable early result during infancy. This type of repair can be effective in delaying the timing for more definitive solution. Therefore, the ability to perform a successful complex valvuloplasty would be of significant clinical benefit in some specific cases. However, further experience is warranted to confirm the safety and durability of this strategy in infants.
