Purpose : After mitral annuloplasty in mitral valve repair, short or tethered posterior leaflet or insufficient areas of both leaflets may cause residual or recurrent mitral regurgitation due to poor or low coaptation height. In such patients, we performed patch augmentation of the posterior leaflet to increase height of the leaflet coaptation, resulting in stable valve competence.
Methods : From September 2009 to August 2016, there were 22 patients (age: median, 63 years; range, 15-75 years) who had a poor coaptation of two mitral leaflets due to short height, tethering of the posterior leaflet, or insufficient areas of both leaflets, and who had patch augmentation of the posterior leaflet (short posterior leaflet, 13 patients; rheumatic mitral steno-insufficiency, 3 patients; and ischemic mitral regurgitation, infective endocarditis, or repair of endocardial cushion defect, 2 patients each).
Results : During mean follow-up of 61 ± 15 months, no patients had mitral regurgitation > 2+. The mean valve pressure gradient was 4 ± 2 mmHg and valve area 2.5 ± 0.4 cm2. No patients required a second operation during follow-up.
Conclusion : In mitral valve repair, the heights of the two leaflets should be considered for proper leaflet coaptation, resulting in stable valve competence. Low coaptation height causing residual or recurrent regurgitation can be resolved by patch augmentation of the posterior leaflet.
