Optimizing P2 Neochordal Length and Stability in Mitral Valve Repair With Use of a Polypropylene Loop.

Optimizing P2 Neochordal Length and Stability in Mitral Valve Repair With Use of a Polypropylene Loop. Tex Heart Inst J. 2020 Jun 01;47(3):207-209 Authors: Ozen A, Unal EU, Ozbek HM, Yigit G, Iscan HZ Abstract 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. PMID: 32997772 [PubMed - in process]
