Introduction. Children aged 7–14 years with congenital heart defects (CHD) often present with prolonged preoperative hemodynamic overload and cardiac remodeling. Aim is to assess defect structure, comorbidity, postoperative syndrome profile, hemodynamics, and echocardiographic changes after surgical correction.

Materials and Methods. Retrospective cohort study.

Results. Shunt defects predominated: ASD 43.8%, PDA 18.8%, VSD 9.4%; extracardiac comorbidities were present in 53.1%. Early postoperative period was characterized by cardiac dysfunction/heart failure.

Laboratory findings showed significant anemia and systemic inflammatory response. Biochemistry revealed increased urea with reduced creatinine and a tendency to decreased total protein, without signs of significant hepatic injury. Echocardiography demonstrated preserved LV ejection fraction (69.6 ± 0.7%) with right ventricular remodeling in 31.3% and left atrial enlargement in 18.8%.

Conclusions. Early postoperative course is mainly determined by cardiac adaptation, while laboratory changes reflect anemia/hemodilution and inflammation without clear evidence of acute renal or hepatic failure in most patients.

Key words: congenital heart defects, school-age children, postoperative period, heart failure, inflammatory response, echocardiography.
