Fig 2 (A) The points of the device are inserted into the loops formed by the neochordae. The Y-points of the inner bar are hooked onto the knot of the expanded polytetrafluoroethylene (ePTFE) suture on the papillary muscle. (B) The facing leaflets are simultaneously grasped by the T-arms of the outer tube. The two parts are adjusted by sliding so that the normal chordae are stretched and taut. After both parts are fixed with a screw and both leaflets are held in the same plane, the ePTFE suture is tied down.
