Abstract

Introduction: Tetralogy of Fallot is a common cyanotic congenital heart defect requiring surgical repair. Despite advances in surgical techniques, a portion of patients demonstrates postoperative cardiovascular maladaptation. This study aimed to evaluate the features of cardiovascular adaptation in different postoperative periods.

Materials and Methods: Eighty children after early surgical repair (mean age 7.2 ± 2.0 months) were examined. Hemodynamics, echocardiographic parameters, rhythm disturbances, and exercise tolerance were analyzed across several follow-up stages.

Results: Positive hemodynamic dynamics were observed in 81.3% of patients. In 72%, transient enlargement of right ventricular end-diastolic volume was detected, with functional recovery by one month. Arrhythmias occurred in 15% early and 5% at six months. Exercise tolerance increased by 25% by three months.

Discussion and conclusion: Cardiovascular adaptation proceeds in a stepwise manner and is influenced by myocardial condition, bypass duration, and hypoxic burden. Comprehensive monitoring is essential for optimizing postoperative management and improving long-term outcomes.
