Paediatric Melody® mitral valve replacement in acute endocarditis - alternative surgical-hybrid technique.

BACKGROUND AND AIM: Acute endocarditis (AE) is still rare disease in the paediatric population; nevertheless, the children suffering from AE usually need heart valve repair or replacement in emergency settings.

METHODS

We present a case of emergency mitral valve replacement with the use of Melody balloon expandable stented bioprosthesis in a two-year-old patient with AE and subsequent mitral (bicuspid) valve incompetence after aggressive infective destruction with the symptoms of critical multi-organ failure.

RESULTS

The patient, with a history of rapid deterioration after two-week-long septicaemia in the course of AE, was operated urgently after initial antibiotic treatment because of huge vegetations into the mitral valve orifice. A Melody TVP 22 valve was expanded over a 16-mm TyShak balloon and implanted into a mitral position (Melody-MVR) with good result.

CONCLUSIONS

Based on current knowledge concerning heart valve reconstructions and institutional experience, we conclude that infected mitral valve in children should be primarily repaired; nevertheless, the Melody valve could be reasonably con-sidered as a mitral prosthesis in such conditions.
