(a) Preoperative echocardiogram: apical four-chamber view showed severe mitral regurgitation. (b) Postoperative echocardiogram, parasternal long axis view. (Arrow indicates the sling.) (c) Postoperative echocardiogram showed trivial mitral regurgitation and good coaptation of mitral valve. (Arrow indicates the loop of tube around the papillary muscle.) (d) The gross finding of the excised heart. (Arrow indicates the loop.) (LA = left atrium; LV = left ventricle.)

Concept of papillary muscle sling in different groups of patients. (a) Dilated left ventricle with poor coaptation resulting in mitral regurgitation. (b) Concept of adult patients group. The papillary muscle sling is over the base of the papillary muscles. (c) Concept of infant group. The papillary muscle sling encircles the papillary muscle.
