Description
Yutaka Okita and Ryo Kawabata defend a heart valve repair in a 2026 reply to the editor. Commenting on their earlier article, a colleague questioned their approach to the unicuspid aortic valve, a birth defect where the valve opens through a single leaflet instead of three.
The authors explain why they rebuild it as a symmetric two-leaflet valve: better flow and a simpler operation. The new hinge point must sit exactly opposite the natural one at the same height, and they describe minimizing borrowed tissue in the leaflet belly. They also explain their disagreement with a rigid ring alternative.
