Background. In the sur­gi­cal ­repair of tet­ral­o­gy of Fallot or pul­mo­nary atre­sia, pul­mo­nary regur­gi­ta­tion may be det­ri­men­tal in the post­op­er­a­tive peri­od. We ­have ­used homo­graft mono­cus­pid ­valve ­patch to pre­vent pul­mo­nary insuf­fi­cien­cy.
Methods. From September 1996 to December 1998, twen­ty-­five ­patients, 4 ­months to 8 ­years of age (­median 10.1 ­months) had homo­graft mono­cus­pid ­valve in the pro­ce­dure of ­right ven­tric­u­lar out­flow ­tract recon­struc­tion. The func­tion of the mono­cus­pid ­valve was ­assessed by ech­o­car­di­o­gram and grad­ed as triv­i­al to ­mild, ­mild to mod­er­ate, mod­er­ate, and ­severe. We eval­u­at­ed the ­degree of pul­mo­nary insuf­fi­cien­cy ­before dis­charge, at 3-6 ­months, and at 12 ­months ­after the oper­a­tion.
Results. There was one hos­pi­tal ­death due to ful­mi­nate ade­no ­viral pneu­mo­nia. On ech­o­car­di­o­gram, 21 ­patients (88%, 21/24) had no sig­nif­i­cant pul­mo­nary insuf­fi­cien­cy. Only one ­patient (4.5%) ­showed a mod­er­ate ­degree of pul­mo­nary insuf­fi­cien­cy. At 3-6 ­months, sev­en­teen of twen­ty-one (81%) ­patients had no sig­nif­i­cant pul­mo­nary insuf­fi­cien­cy. There ­were four­teen ­patients who had fol­low-up ­over 1 ­year, and no ­patients ­showed new­ly devel­oped sig­nif­i­cant pul­mo­nary insuf­fi­cien­cy.
Conclusions. We con­clud­ed ­that the homo­graft mono­cus­pid ­valve ­patch for ­right ven­tric­u­lar out­flow ­tract recon­struc­tion has pro­vid­ed excel­lent ear­ly ­results for the pre­ven­tion of pul­mo­nary insuf­fi­cien­cy. However ­these ­effects are lim­it­ed in dura­tion and fur­ther ­close fol­low-up ­should be need­ed.
