Abstract

We successfully repaired a hammock mitral valve associated with severe mitral valve regurgitation in a 4-month-old boy using posterior leaflet extension along with glutaraldehyde-treated autologous pericardium and the splitting of bilateral papillary muscles. Surgical reinterventions were performed for the bilateral papillary muscles at 14 and 24 months postoperatively. The extended autologous pericardium was still pliable with mild mitral valve regurgitation at 26 months postoperatively.
