New Method of Posterior Scallop Augmentation for Ischemic Mitral Regurgitation Masakazu Aoki, MD, Toshiaki Ito, MD, PhD The Annals of Thoracic Surgery Volume 99, Issue 3, Pages 1087-1089 (March 2015) DOI: 10.1016/j.athoracsur.2014.09.080 Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

Fig 1 (A) Glutaraldehyde-treated autologous pericardium was trimmed into a narrow pentagon shape. A reversed T-shape incision was made in the P2 scallop. (B) The straight edge of the pericardium was sutured to the angled cut edges of P2. The three-dimensionally reconstructed P2 leaflet bulged toward the center of the valve. The summit of the pericardium was directly attached to the anterior papillary muscle (APM).

Fig 2 Intraoperative view. The P2 scallop was enlarged with the pericardium. The Annals of Thoracic Surgery 2015 99, 1087-1089DOI: (10.1016/j.athoracsur.2014.09.080) Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

Fig 3 Postoperative long-axis view of the mitral valve in (A) diastole and (B) systole (transesophageal echocardiogram). (A) Enlarged P2 scallop has an adequate valve opening. (B) The A2 and P2 leaflets coapted near the mitral annular plane, and the coaptation was very deep.
