Reducing the posterior wall length by using a small endoventricular patch for ischemic mitral regurgitation Hiroshi Tanaka, MD, Kenji Okada, MD, Keitaro Nakagiri, MD, Yujiro Kawanishi, MD, Masamichi Matsumori, MD, Yutaka Okita, MD The Journal of Thoracic and Cardiovascular Surgery Volume 133, Issue 6, Pages 1633-1635 (June 2007) DOI: 10.1016/j.jtcvs.2007.01.036 Copyright © 2007 The American Association for Thoracic Surgery Terms and Conditions

Figure 1 A, Preoperative echocardiogram showing a posterior basal aneurysm (white arrow) and severe mitral regurgitation caused by the posterior mitral leaflet tethering retracted to the posterior papillary muscle during systole 10 mm in depth (white line). B and C, Postoperative echocardiography showing no tethering of the posterior mitral leaflet. The white arrow indicates the endoventricular patch. Dd, Dimension diastole; Ds, dimension systole; FS, fractional shortening.

Figure 2 A, Preoperative. Posterior basal aneurysm causing dislocation of the posterior papillary muscle from the mitral leaflet, which provokes leaflet tethering (small arrow). The white arrow indicates mitral regurgitation. B, Postoperative. A small-sized patch applied to the aneurysm prevents the posterior papillary muscle from moving away from the mitral leaflet.
