Fig 1 Modified edge-to-edge technique. (A) A pledget-reinforced horizontal mattress stitch with No. 5-0 polypropylene, with the knot tied on the ventricular side. (B) Lateral view of this suture. (C) A pledget-reinforced mattress stitch with Gore-Tex suture (W.L. Gore & Associates, Flagstaff, AZ) and Dacron pledgets (Chest, Shanghai) placed on the anterior and posterior annulus corresponding to the edge-to-edge suturing site. (D) The Gore-Tex suture is passed into the mitral valve leaflets. The Annals of Thoracic Surgery , e89-e91DOI: ( /j.athoracsur ) Copyright © 2011 The Society of Thoracic Surgeons Terms and Conditions

Fig 2 Apical four-chamber view of preoperative echocardiographic images showing prolapse of the anterior leaflet (A) and severe mitral regurgitation (B) with color Doppler echocardiography. Postoperative parasternal short-axis view showing the double-orifice mitral valve (C) and intuitive image with real-time three-dimensional echocardiography (D). Directed jet of double-orifice mitral valve (E) and transvalvular pressure gradients calculated in color Doppler echocardiography are normal (F). (LA = left atrium; LV= left ventricle; RA = right atrium; RV = right ventricle.)
