Popis: | Objetivos Analizar los resultados a largo plazo de la operacion de Ross en pacientes pediatricos. Material y metodos Entre 1995-2008, 33 pacientes de edad media 7,27 ± 4,8 anos (5-28) recibieron autoinjerto pulmonar. Cirugia previa en 10, dilatacion percutanea en 13. Las indicaciones fueron estenosis neonatal con fibroelastosis (3), sindrome de Shone (3), doble lesion (16), insuficiencia (8), estenosis (2) y endocarditis sobre aneurisma roto de seno de Valsalva (2). Se realizaron 22 sustituciones de raiz, tres tecnicas de inclusion y ocho operaciones de Ross-Konno. En dos se realizo sustitucion de valvula mitral. Resultados Mortalidad hospitalaria tres casos. No mortalidad tardia. Seguimiento completo de 6 meses a 13 anos (media 5,6). El autoinjerto mostro insuficiencia moderada-grave en seis casos, trivial-ligera en 27. Tres reoperaciones relacionadas con el autoinjerto, sin reoperaciones del homoinjerto. Supervivencia actuarial 90,9 ± 5,0% a 13 anos. Libertad de reintervencion o fallo del autoinjerto 88,4 ± 6,3% a 13 anos. Conclusiones Las intervenciones de Ross y Ross- Konno han cambiado el pronostico de pacientes pediatricos con enfermedad compleja de la raiz aortica. En pacientes jovenes se detecta crecimiento de la neorraiz aortica. Se detecta dilatacion del autoinjerto a nivel sinotubular con insuficiencia de la neovalvula aortica, con la sustitucion de raiz en pacientes con insuficiencia previa. Los mejores resultados se obtienen en los pacientes de menor edad y peso, con obstrucciones complejas del tracto de salida izquierdo y sin dilatacion de raiz. Un riguroso control de los pacientes con raiz aortica dilatada es obligatorio para validar el Ross frente a las protesis. Objective To analyze the long-term results of the Ross operation in pediatric patients. Methods From 1995-2008, 33 patients with a mean age of 7.27 ± 4.8 years underwent the Ross operation. Ten patients had a previous operation and 13 percutaneous valvotomies. Indications for operation were critical neonatal aortic stenosis with fibroelastosis (3), Shone syndrome (3), mixed lesion (16), insufficiency (8), stenosis (2) and endocarditis on ruptured aneurysm of sinus of Valsalva (1). Root replacement was performed in 22 cases, inclusion technique in 3 and a Ross-Konno in 8. Mitral valve replacement was performed in 2. Results Three patients died after surgery. There was no late mortality. Follow-up is complete from 6 months to 13 years (mean 5.6 years). There was moderate-severe autograft incompetence in 6 and trivial-mild in 27. Three patients required autograft- related reoperation; no homograft reoperations. Actuarial survival is 90.9 ± 5.0%; freedom from autograft failure or reoperation is 88.4 ± 6.3% at 13 years. Conclusions The Ross and Ross-Konno operations have changed the prognosis of pediatric patients with complex disease of the valve and aortic root. There is growth of the neo-aortic root in young patients. Sinotubular dilatation of the autograft with neoaortic valve insufficiency has been detected in patients with previously dilated aortic root when root replacement technique was performed. The best results are obtained in the younger andlower weight patients with complex left ventricular outflow obstruction without root dilatation. A close follow-up of patients with aortic root dilatation is mandatory to definitely validate the Ross procedure over aortic prosthesis. |
