[The work capacity of patients operated on for congenital heart defects].

A study is presented of the results of surgical treatment and the status of working capacity in 8,072 patients operated on for congenital heart disease. The results were good in 62%, fair in 30%, poor in 4% of these patients. There was a significant discrepancy between the state of invalidity as it was established by the medical expert commission and results of surgical treatment related to overestimation of the fact of surgical intervention and inadequate approach of evaluation of the health condition of the patients undergoing surgery based on the nosological form and initial severity of the disorders of cardiodynamics.
