[An infant case of a rupture of chordae tendineae; report of a case].
We report a case of 5-month-old boy with severe mitral regurgitation due to a rupture of chordae tendinae. Cardiac echography showed a prolapse of the anterior cusp of the mitral valve. He was progressively deteriorated despite maximal medical treatment, and a surgical intervention was performed 15 hours after the onset. The operative finding was a rupture of chordae tendinae attached to the anterior cusp of the mitral valve. The infant underwent mitral valve plasty using artificial chordae together with partial annulo-plasty. A rupture of chordae tendineae is extremely rare in infants, and its cause is yet unknown. Chordal reconstruction is feasible even at this early stage of life, although the long-term follow-up is mandatory.
