Forty-seven infants with ventricular septum (n=19), tetralogy of Fallout (n=8) and transposition of the great(n=28) who underwent "corrective" surgery in their first year of life were examined for their birth weight and their pre- and post-operative status. postoperative growth. The average birth weight for each group was lower than that of the standard population. Our current research was conducted at Sir Ganga Ram Hospital, Lahore from March 2019 to April 2020. There was a decrease in the growth rate in preoperative period which was reversed after the operation. At follow-up, 13-1 9 months later (mean), Most of the infants had regained at least their birth weight percentile, while the group with ventricular communication exceeded it. The pathophysiological mechanisms contributing to these observations are considered. Keywords: Cardiovascular surgery, first year of life, weight gain of children with congenital heart defects.
