Abstract
In the current issue of EJCTS, Aszyk et al. present their excellent experience with the Konno-Ross operation in 16 infants, primarily having complex left ventricular outflow tract obstruction (LVOTO) [1]. Five patients were below 1 month of age. There was no operative mortality, although some early morbidity was noted. Importantly, the authors documented an extremely gratifying outcome at a median follow-up of 6.2 years, especially for infants with no structural abnormality of the mitral valve. Aortic regurgitation was absent or trivial in all cases, with complete and sustained resolution of LVOTO, as well as preservation of ventricular function. This outcome is concordant with my personal Konno-Ross operation experience in neonates and infants operated over the past 15 years in the USA and Australia. My impression is that the experience (published and unpublished) of other groups would largely support the data presented herein [2–7]. There are a few comments and observations that I would like to offer regarding the Konno-Ross operation in infancy:
