title: The butterfly technique.
abstract: Butterfly resection is a mitral valve repair technique for prolapsing posterior leaflets. The aim of butterfly resection is to optimize the geometry of the resultant new leaflet, with controlled height reduction for a prolapsing segment, without annular reduction. We have reported the concept of its design, its advantages in preventing post-repair systolic anterior motion (SAM), and excellent early and medium-term results. The present illustrated article describes the technical details of how we design and perform the butterfly technique.
