Face-to-face single patch: A new technique to repair the commissures of the mitral valve Samer Kassem, MD, PhD, Khalid Al-Faraidy, MD, Yasser Elkady, MD, Ahmad Takriti, MD The Journal of Thoracic and Cardiovascular Surgery Volume 144, Issue 6, Pages 1523-1527 (December 2012) DOI: 10.1016/j.jtcvs.2012.07.079 Copyright © 2012 The American Association for Thoracic Surgery Terms and Conditions

Figure 1 A, Illustration of calcification and fusion of posterior commissure, extension of A3 and P3 fibrosis, and attached and relatively healthy chords. B, The commissural calcifications and fused chords are resected en bloc. The nearest relatively healthy chords of anterior and posterior leaflets to bloc of commissure are conserved. The illustration shows the 5 distinct components of the 3-dimensional defect: anterior leaflet (B-C), posterior leaflet (A-D), 2 sets of native chords (E-C and F-D), and mitral annulus (A-B). C, Illustration showing new chord anchored on medial head of the posterior papillary muscle. The assistant surgeon stretches the annulus adjacent to the right trigone using a nerve hook. Next, the surgeon places a metal clip across the 2 arms of the new chord at the level of the annulus. Several nonsliding knots are tied against the metal clip, which is subsequently removed.

Figure 2 A, The 5 components are measured individually using a free surgical thread and metal clips. The length of each thread's component must exceed by 1 cm the actual length of the same measured segment. B, A patch of fresh autologous pericardium is fashioned into a right-angle trapezoid shape using the previously recorded measurements of the several components of the defect. A triangle is resected from the trapezoid's surface between the 2 bases without passing the c-d line. Six stay sutures, of 5-0 yellow monofilament Radene (Dynek), are passed through the projected points (a, b, c, d, e, and f) of the patch, keeping it spread out. C, The patch is fixed to the posterior and anterior angles of the annulus component (A and B) with corresponding (a and b) stay sutures and attached to the chordal inserts on the anterior and posterior leaflets (C, D) with corresponding (c, d) stay sutures. Next, running 5-0 Radene suture is used to approximate the patch to the annulus component. The 2 windows between the patch and free margins of the resected anterior and posterior leaflets are closed with interrupted 5-0 Prolene sutures knotted toward the ventricular side of the suture lines. D, Illustration showing patch anchored to papillary head. A sized Physio annuloplasty ring is implanted, and Gore-Tex sutures are passed through corresponding trigone prosthetic sheath and tightly knotted.
