Artificial Chordae

Determining the optimal length of artificial chordae tendineae and then effectively securing them is a major challenge in mitral valve repair. Our technique for measuring and stabilizing neochordae involves tying a polypropylene suture loop onto the annuloplasty ring. We used this method in 4 patients who had moderate-to-severe mitral regurgitation from degenerative posterior leaflet (P2) prolapse and flail chordae. Results of intraoperative saline tests and postoperative transesophageal echocardiography revealed only mild insufficiency. One month postoperatively, echocardiograms showed trivial regurgitation in all 4 patients. We think that this simple, precise method for adjusting and stabilizing artificial chordae will be advantageous in mitral valve repair.

Repair Techniques

Mitral valve regurgitation may require complex repair techniques that are challenging in minimally invasive and may expose patients to prolonged cardiopulmonary bypass and cross-clamp times. Here, we present a stepwise operative approach that may facilitate the repair of the mitral valve in a minimally invasive fashion and may be carried out even when multiple posterior segments are involved. This how-to-do article presents a method that was performed in 148 patients that were referred to our institution for severe organic mitral regurgitation between 2008 and 2016. At mean ± SD follow-up of 45.5 ± 27 months, freedom from recurrent of mitral regurgitation 2+ or greater and reoperation was 95.2%.

Leaflet Prolapse

Degenerative mitral regurgitation due to posterior leaflet prolapse is often associated with tissue redundancy in the leaflet height and free margin of the prolapsing segment. The butterfly technique has been introduced for focal resection to precisely control the leaflet height without annular plication. This technique is indicated for a high prolapsing leaflet, greater than 20 mm. With intraoperative measurement of leaflet heights and ink dot marking as a depth indicator, the butterfly technique can be safely performed in most high posterior leaflet prolapse cases, without increasing the risk of systolic anterior motion.
