Late results after mitral valve replacement with bileaflet mechanical prosthesis in children: evaluation of prosthesis-patient mismatch

Abstract

Although numerous reconstructive measures of mitral valve have been reported to avoid valve replacement in young children [ 1 x 1 Aharon, A.S., Laks, H., Drinkwater, D.C. et al.

Mechanical prosthesis is the choice of valve replacement at the mitral position in children because durability of biologic prostheses in children is known to be worse when compared with that in adults [ 7 x 7 Ilbawi, M.N., Idriss, F.S., Deleon, S.Y. et al.

Mitral valve replacement in small children has more difficulties when compared with that in adults, not only at the time of implantation but also throughout follow-up management. Anticoagulation regimen in small children is considered cumbersome and troublesome [ 8 x 8 Vogel, J.H.K. The St. Jude Medical cardiac valve in infants and children (role of anticoagulant therapy) .

Re-replacement of prostheses because of somatic growth of the patients is almost inevitable when prostheses were implanted in small children.
