Mitral commissural repair with autologous fresh pericardium in an infant.

We describe the successful mitral valve repair with autologous fresh pericardium in a 5-month-old infant with acute progressive mitral regurgitation. The intraoperative findings consisted of fragile mitral valve leaflets with multiple chordal rupture of both the anterior and posterior leaflets. The disrupted anterolateral commissure was reconstructed using autologous fresh pericardium, a technique not previously reported in an infant of this size. Follow-up echocardiography for up to 7 years showed only trivial mitral regurgitation and no mitral stenosis.
