Material: 34 children (16 boys and 18 girls) with
tetralogy of Fallot, aged 2 mths - 16 yrs 9mths. In 88% of cases the defect
was detected occasionally in the first month of life. In 17 children (50%)
paliative procedures were performed (B - T anastomosis, pulmonary
vulvoplasty) at the age 4 days to 3 yrs 8 mths. In 30 children (88%) total
correction of the defect was performed at the age of 5 mths - 7 yrs 4 mths.
Results: The echo examination of the heart detected: 1.
remaining stenosis on the way of outflow from the right ventricle with the
gradient of systolic pressure between the right ventricle and pulmonary
artery < 40 mmHg - in 100% of cases, 2. remaining ventricular-septal
defect, insignificant haemodynamically in 2 patients (6.6%) and significant
haemodynamically in 1 patient (3.3%),
3. pulmonary regurgitation of 1st and 2nd
degree in 20 patients (66.6%), 4. tricuspid regurgitation of 1st
and 2nd degree in 5 patients (16.6%), 5. anastomosis
recanalisation in 1 child (3.3%), 6. left pulmonary artery stenosis in 1
child (3.3%).
Conclusions: 1.Good and very good results of total
correction were obtained in 83% of patients. 2.Pulmonary regurgitation was
most common remaining anatomical abnormality. 3.Patients with tetralogy of
Fallot cadiosurgically corrected require systematic cardiological follow-up
evaluation.
