We generally chose a semirigid (Memo 3D) ring in patients whose annular height-to-commissural width ratio was normal (\u2265 15%). The same semirigid ring with an additional chordal guiding system (Memo 3D ReChord) was selected for patients with anterior leaflet or bileaflet pathology. Over an 18-month period, 66 patients with severe degenerative ( n\u2009=\u200960) or functional ( n\u2009=\u20096) mitral regurgitation had Memo 3D ( n\u2009=\u200932) or Memo 3D ReChord ( n\u2009=\u200934) rings implanted.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Postoperative 3-dimensional transesophageal echocardiography was completed in all patients (mean follow-up 7\u2009\u00b1\u20095 months). The majority of patients had no or mild residual mitral regurgitation; only two had moderate (2+) mitral regurgitation.
