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.

AbstractWe performed “Papillary muscle heads focalization” for three patients with severe functional mitral regurgitation with severe leaflet tethering (coaptation distance ≥1 cm and/or posterior leaflet angle ≥45 degrees). All separated papillary muscle heads were sutured together and both the anterolateral and posteromedial papillary muscles were reconstructed as single head papillary muscles. The stitches are positioned to adjust the levels of mitral leaflet tips, concerning the length of the marginal chordae connected to each head. A downsized annuloplasty is performed concomitantly. At discharge, no patient showed moderate/severe mitral regurgitation. Their coaptation lengths were 7.1, 8.5, and 8.3 mm.
