[The changes of the methods of the right ventricle outflow tract reconstruction]

There are many situation that we need to do some procedure for the right ventricle outflow tract reconstruction (RVOTR) among the congenital heart diseases. The procedures have changed during past decade. Also the changes have shown about the materials for outflow patches. We reviewed the changes through our experience. There were seventy-six cases or RVOTR from August, 1988 to December, 2000. Most of them were tetralogy of Fallot. Fifteen cases were done the Rastelli procedure. There were some other congenital heart diseases. The materials were mainly artificial in the period before 1995. Then it has been changed mainly to the autologous pericardium in the period after 1996. The sizes of the tract were made to match the standard of Rowlatt. We found some re-stenosis and late mortality because of the pulmonary valve regurgitation. We are trying to reduce such complications.
