Table 2:
Techniques for the repair of the posterior (or both) mitral leaflets
| Study | Method of anchor to papillary muscle | Method of anchor to leaflet | Method of adjusting length | Knot tying | Annuloplasty ring | Special features |
|---|---|---|---|---|---|---|
| David 2004 [11] | 3 | B1 | 1 | 0 | 1 | The length of each chordae loop varies with the stress pattern |
| Cimen et al. 2006 [31] | 1 | A1 | 1 | 2 | 0 | Knots are tied under LV filling conditions |
| Tam et al. 2006 [26] | 1 | A2 | 3 | 0 | 1 | Callipers are used to make loops of predetermined length, which are attached to leaflet and PM |
| Not adjustable | ||||||
| Kudo et al. 2009 [37] | 1 | A4 | 3 | 1 | 0 | After standard loop technique, a reduction 4-0 polyester suture is used to reduce prolapse of the leaflet in Barlow's disease |
| Isoda et al. 2012 [51] | 3 | 3 | 1 | 0 | 0 | This involves an anchor loop fixed to the papillary muscle |
| A series of loops to the approximate length required is made and tied to the papillary anchor point | ||||||
| The loop is fixed to the leaflet using additional small anchoring loops | ||||||
| If the length need to be adjusted, additional anchor sutures are placed to shorten the loop |
