Late results of valvoplasty for mitral regurgitation due to rupture of chordae of the posterior (mural) cusp.

Nine patients with rupture of chordae tendinea of the posterior cusp of the mitral valve are presented. All have been treated by plication of the posterior cusp and atrial wall. The presenting postoperative features have been described: 89 per cent are markedly improved; two patients have normal heart sounds with no murmurs; 6 patients have only a Grade 1 pansystolic apical murmur. The advantages of this procedure compared with mitral valve replacement for the same condition have been presented.
