My 2 year old daughter had open heart surgery at 4 months old for DORV with VSD. Her surgery was successful. Now at 2 years and 4 mths I brought her to her pediatrician bc I noticed her breathing was rather extra Heavy after running around. He said her heart sounded fine and her breathing while there was fine. However he did notice her liver was enlarged. This is new bc up until now her liver was fine. What could be the cause for this? Is it something we need to worry about? Will her liver get back to its normal size?
