1 Use of an Expanded Polytetrafluoroethylene Patch as an Artificial Leaflet in Mitral Valve Plasty: An Early Experience  Toshiaki Ito, MD, Atsuo Maekawa, MD, Koji Yamana, MD, Tomo Yoshizumi, MD, Masatoshi Sunada, MD  The Annals of Thoracic Surgery  Volume 89, Issue 5, Pages (May 2010) DOI: /j.athoracsur Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 A 0.4-mm Gore-Tex patch (W.L. Gore & Assoc, Flagstaff, AZ) sutured at the base of the anterior mitral leaflet in ischemic mitral regurgitation. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 (A) Systolic and (B) diastolic echocardiographic images at 46 months postoperatively in a 72-year-old man who underwent anterior mitral valve augmentation with a Gore-Tex patch (W.L. Gore & Assoc, Flagstaff, AZ) for ischemic mitral regurgitation. The motion of the Gore-Tex patch at the basal portion of the anterior leaflet is preserved. The high echocardiographic image of the patch is due to the properties of Gore-Tex and does not imply calcification. The motion angle of the patch was directly measured on digital images.
