aortic valve cusp plication
Pronunciation: /ˈplɪkeɪʃən/
A valve-sparing surgical technique involving the folding and suturing of redundant aortic valve cusp tissue. Used to correct cusp prolapse and restore valve competency.
Full Definition
Aortic valve cusp plication is a reconstructive surgical procedure used in valve-sparing aortic root surgery to address cusp prolapse or redundancy. The technique involves creating pleats or folds in the excessive cusp tissue using fine sutures to restore proper coaptation geometry. This procedure is often performed in conjunction with aortic root replacement when the valve leaflets are structurally sound but geometrically distorted. Proper plication requires careful assessment of cusp effective height and geometric relationships. The goal is to achieve symmetric cusp motion and eliminate regurgitation while preserving the patient's native valve.
Usage
Usage note: Distinguish from cusp resection, which removes tissue rather than folding it.
