1 A Device for Ensuring the Neochordae Replacement in Mitral Valve Repair 
Hiroshi Iida, MD, PhD, Toru Sunazawa, MD, Atsuo Doi, MD, Keiichi Ishida, MD, PhD, Shinichiro Irabu, MD  The Annals of Thoracic Surgery  Volume 90, Issue 6, Pages (December 2010) DOI: /j.athoracsur Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Double-armed sliding double hook composed of two hooks with double arms: an inner bar with Y-shaped points and an outer tube with T-shaped arms. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions

3 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.
