ABSTRACT
Mechanical prosthesis is the first choice for valve replacement at the mitral position in children. Replacement of the original prosthesis because of prosthesis-patient mismatch (PPM) is almost inevitable when prostheses are implanted in small children. The impact of PPM on long-term mortality becomes significant when the effective orifice area (EOA) is severely reduced. In these cases prosthesis replacement can be technically difficult, and it often requires extended enlargement of the mitral valve annulus ring. We report a case of a woman who underwent a mitral valve replacement with a 19-mm St. Jude mechanical prosthetic valve at the age of 3 years. At the age of 33 years, the patient underwent a successful minimally invasive mitral annulus ring enlargement and implantation of a 23-mm St. Jude mechanical prosthetic valve via a right minithoracotomy.
