Background. Complex ­left ven­tric­u­lar out­flow ­tract (LVOT) obstruc­tion in chil­dren con­tin­ues to ­pose a sig­nif­i­cant ther­a­peu­tic chal­lenge to car­diac sur­geons. The Ross pro­ce­dure, in com­bi­na­tion ­with resec­tion of sub­aor­tic sten­o­sis or a Konno ­type sep­tal inci­sion, is an impor­tant ­option for ­these dif­fi­cult ­patients.
Methods. Recently two chil­dren ­aged 14 and 5 ­years ­with ­LVOT obstruc­tion involv­ing com­bined sub­aor­tic and val­var sten­o­sis under­went sur­gi­cal cor­rec­tion ­using the pul­mo­nary auto­graft. Clinical pres­en­ta­tion, oper­a­tive tech­nique, out­come and inter­me­di­ate fol­low-up are ­detailed.
Results. One ­patient had resec­tion of an iso­lat­ed subaor­tic mem­brane in com­bi­na­tion ­with a pul­mo­nary auto­graft and the sec­ond a Ross Konno pro­ce­dure. Postoperative hos­pi­tal ­stays ­were with­out com­pli­ca­tion. Both ­patients ­were dis­charged at 5 ­days and ­have no sig­nif­i­cant obstruc­tion nor sem­i­lu­nar ­valve insuf­fi­cien­cy at 3 ­years’ fol­low-up.
Conclusions. Pulmonary auto­grafts can be ­used in com­bi­na­tion ­with resec­tion of sub­aor­tic tis­sue or a sep­tal inci­sion for recon­struc­tion of com­plex ­left ven­tric­u­lar out­flow ­tract obstruc­tion. This tech­nique ren­ders excel­lent ­short ­term ­valve func­tion, ­relief of obstruc­tion, ­avoids anti­co­ag­u­la­tion and pro­vides poten­tial for ­future ­growth.
