Abstract
Background: It is now known from a previous midterm study that, Primary ASO can be safely performed in children with regressed ventricle, irrespective of age with encouraging results1. Here we are reporting the long term cardiopulmonary fitness in children who have undergone primary ASO, for d-TGA with regressed ventricle and d-TGA with preserved ventricle between the year 2006-2014 and its comparison with that of an age matched control group.
Materials and Methods: Data of Children who underwent ASO between the year 2006-2014 by Dr. A.K Bisoi were collected and divided in to 2 groups of those who had regressed LV at the time of surgery and those who had preserved LV. Total 18 children were called for CPET and the results compared with that of 20 age matched control group children.
Results: In the present study no difference was found in rate of oxygen consumption (VO2 max) of post ASO children {group A + group B :34.23ml/kg/min} and control group children{group C:36.84ml/kg/min}.
Conclusion: Cardiopulmonary performance over long term after an ASO, irrespective of preserved or regressed LV at the time of ASO, is at par with normal children; rather it improves with age related catch up growth post operatively.
