Reconstruction of mitral valve chordae and leaflets with one piece of autologous pericardium in extensively destructed mitral valve due to active infective endocarditis.

A 20-year-old female patient underwent urgent surgery for extensive mitral valve endocarditis. All marginal chordae and rough zone of A3 leaflet, posterior commissure leaflet, and P3 leaflet down to the annulus became defective after complete debridement of infected tissues. After annular plication, defective leaflets and chordae were reconstructed with a piece of triangular shaped autologous pericardium. Top of the pericardium was directly attached to the posterior papillary muscle, side edges to remnant leaflets, and the base to the annulus, thus substituting for chordae and leaflets at once. No mitral regurgitation was observed during 3 years of follow-up after the operation.
