INTRODUCTION: There is an increasing ratio of surviving patients with congenital heart disease including tetralogy of Fallot. OBJECTIVE: The aim of the present study was a comparative assessment of echocardiographic and cardiac magnetic resonance imaging-derived findings in patients with tetralogy of Fallot following early total reconstruction versus early palliation/late correction. METHODS: The study comprised 17 patients with tetralogy of Fallot (mean age: 28.6 ± 10.4 years; 10 males). Early total reconstruction was performed in 10 cases (mean age: 25.0 ± 8.0 years; 8 males), while early palliation/late construction was done in 7 subjects (mean age: 33.7 ± 11.8 years; 2 males). Complete two-dimensional Doppler echocardiography and cardiac resonance imaging were performed in all patients. RESULTS: During long-term follow-up, lower left ventricular end-systolic (40.50 ± 10.55 ml/m2 vs. 58.14 ± 19.07 ml/m2, p = 0.013) and end-diastolic volume indices (86.60 ± 12.62 ml/m2 vs. 116.70 ± 23.70 ml/m2, p = 0.002) and stroke volume index (46.00 ± 6.77 ml/m2 vs. 58.43 ± 7.11 ml/m2, p = 0.001) could be detected, which were associated with higher echocardiographic left ventricular ejection fraction (69.75 ± 6.80% vs. 61.67 ± 8.80%, p = 0.038) in patients with tetralogy of Fallot following early total reconstruction as compared to that of subjects late after early palliation/late correction. In regard with the right heart, larger right ventricular muscle mass (72.33 ± 21.03 g/m2 vs. 51.33 ± 22.33 g/m2, p = 0.044) could be seen in patients with tetralogy of Fallot following early total reconstruction. CONCLUSION: Beneficial left ventricular morphological and functional parameters, but more pronounced right ventricular hypertrophy could be detected in patients with tetralogy of Fallot following early total reconstruction as compared to that of subjects late after early palliation/late correction.
