Long-Term Outcomes of Chordal Replacement With Expanded Polytetrafluoroethylene Sutures to Repair Mitral Leaflet Prolapse
David et al. examined the durability of mitral repair using using chordal replacement with expanded polytetrafluoroethylene sutures to correct leaflet prolapse.They evaluated 186 patients who underwent isolated chordal replacement, and 560 patients who underwent both leaflet resection and choral replacement.
David et al. note that chordal replacement with expanded polytetrafluoroethylene sutures provides stable mitral valve function in most patients during the 20 years of follow-up.
