Cirugía de Ross y Ross-Konno en edad pediátrica: ¿es la edad un factor de riesgo?

Abstract

Introduction and objectivesSevere aortic valve stenosis in pediatric population represents a real surgical challenge. Therapeutic options are highly complex, especially in children under one year of age. Ross procedure is indicated in those cases where surgical repair or balloon valvuloplasty has not been feasible. The aim of the study is compare the postoperative outcomes and in the follow-up of patients under one year with all the patients who underwent Ross / Ross-Konno procedure in our centre. MethodsConsecutive patients operated in our centre with these two procedures for the last ten years were collected. During this period, 11 patients were operated (5 Ross and 6 Ross-Konno) of which 3 corresponded to patients under one year of age. ResultsHospital mortality is 9,1% (1 patient) with a 10-year survival of 90,9%. The reoperations percentage is 72,7%, higher in patients less than 1-year-old (100% vs. 62,5%). Only one patient required an autograft reoperation in the adulthood. The right ventricle outflow tract reoperation rate is 64,6% at 10 years. ConclusionsPostoperative mortality and survival at 10 years of patients operated on during the first year of life does not differ from the rest of older patients, although the rate of reoperations in the follow-up is higher in this subgroup of patients.
