Novel knot-tying technique for mitral valve repair Hironori Izutani, MD, PhD, Masao Yoshitatsu, MD, PhD, Jyun Kawamoto, MD, Keijiro Katayama, MD The Journal of Thoracic and Cardiovascular Surgery Volume 129, Issue 5, Pages 1184-1186 (May 2005) DOI: 10.1016/j.jtcvs.2004.09.026 Copyright © 2005 The American Association for Thoracic Surgery Terms and Conditions

Figure 1 The schemes of the knot pusher and its manipulation. Holding the device with one hand, the knot is pushed down after making a knot in the suture, and then the surgeon pulls both ends of the suture with the other hand. The surgeon simply repeats the same maneuver for secure knot tying.

Figure 2 The mitral valve with anterior leaflet prolapse was exposed (A). The chordal replacement sutures were placed on the anterior leaflet (B) and tied with the device (C). The mitral valve repair was completed after ring annuloplasty (D).
