The arithmetic of a successful mitral valve repair Muralidhar Padala, PhD The Journal of Thoracic and Cardiovascular Surgery Volume 154, Issue 5, Pages 1638-1640 (November 2017) DOI: 10.1016/j.jtcvs.2017.07.043 Copyright © 2017 The American Association for Thoracic Surgery Terms and Conditions

Figure 1 A, Schematic of the mitral valve depicting the anterior leaflet (AL) and posterior leaflet (PL). PC indicates the primary chorda, and SC indicates the secondary chorda, with the leaflet section captured between the chordal insertion points being the rough zone of the leaflet. B, Flail of the rough zone on a leaflet in which the primary chorda is ruptured. C, Diastolic configuration of the same valve, depicting the two measurements of importance for the repair: lmax indicates the length from secondary chordal insertion in the leaflet to the papillary muscle; lmin indicates the length from the free edge of the leaflet to the insertion point of the secondary chorda in the papillary muscle. D, Another view of the diastolic configuration: D represents the septolateral annular diameter; A represents the diastolic length of the anterior leaflet; and P represents the diastolic length of the posterior leaflet.
