Correction of bileaflet mitral valve prolapse via reduction of posterior leaflet height

Abstract Mitral regurgitation due to bileaflet prolapse can be corrected with height reduction of the posterior leaflet via detachment at its base, division of accompanying secondary chordae, and leaflet-annular re-approximation. This technique lowers the posterior leaflet height by approximately 1.5 cm, thereby displacing the line of coaptation posteriorly to achieve symmetry without the need for additional artificial chordae. Of the 37 patients who underwent this type of repair at our institution, there were no patients with recurrent MR greater than or equal to 2 at an average follow-up of 1.9 (0.2 – 4.5) years.
