The ­relief of a ­right ven­tric­ular out­flow ­tract obstruc­tion is a cru­cial ­step to suc­cessful trans­atrial-trans­pul­mo­nary ­repair for tet­ralogy of ­Fallot. We ­here ­describe our tech­nique for ­achieving ­good effec­tive ­relief of a ­right ven­tric­ular out­flow ­tract obstruc­tion by ­slicing the ­wall ­without ­right ven­tric­u­lotomy or ­with min­imum trans­an­ular ­right ven­tric­u­lotomy if nec­es­sary. The ­right ven­tric­ular out­flow ­tract can be ­widely ­opened by ­slicing the ­inner ­half of the ­wall ­both ­through the tri­cuspid ­valve and the pul­mo­nary ­valve. ­This pro­ce­dure can be per­formed ­safely and effec­tively by ­detecting struc­tural dif­fer­ences ­between the ­inner and ­outer ­half of the ­right ven­tric­ular ­wall, the ­former ­coarse and the ­latter ­dense.
