Valve-Sparing or Valve Reconstruction Options in Tetralogy of Fallot Surgery

Abstract:
This review deals with a relatively new field in congenital heart surgery, valve preservation or, in cases of more severe pulmonary valve stenosis or dysplasia, valve reconstruction during tetralogy of Fallot repair. We describe the stepwise approach utilized, starting with simple maneuvers such as commissurotomy and valve dilation for mild pulmonary stenosis to commissurotomy and intraoperative balloon dilation for moderate stenosis, and finally transection of the annulus and valve reconstruction using a patch that acts as a modified monocusp. Results are presented and have been gratifying.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
