Background: Surgical repair of tetralogy of Fallot may leave the patient with pulmonary regurgitation causing eventual right ventricle dilatation and dysfunction. Predicting clinical deterioration may help to determine the best timing for intervention.

Objectives: To assess whether the clinical and humoral status of patients in the second decade after repair of ToF[1] is worse than that of patients in the first decade after repair.

Methods: Twenty-one patients with repaired ToF underwent clinical assessment, electrocardiogram, echocardiogram and measurement of plasma B-type natriuretic peptide and N-terminal pro-BNP[2] as well as the 6 minute walk distance test. Patients were divided into two groups: group A – less than 10 years after repair (n=10, age < 12 years old), and group B – more than 10 years after repair (n=11, age > 12 years old). The age at repair was similar in both groups.

Results: In all but one patient the distance in the 6 min walk test was less than the minimum for age. RV[3] end-diastolic volume and the 6 min walk test correlated with age. NT-proBNP[4] levels were significantly higher in the ToF group compared to 26 healthy controls (P < 0.0001) and were inversely correlated with RV ejection fraction. Comparison of the two groups showed no difference in RV end-diastolic volume indexed for body surface area, pulmonary regurgitation severity, right or left ventricular myocardial performance index, RV ejection fraction, QRS duration, or 6 min walk indexed to minimum for age.

Conclusions: In this group of patients with similar age at operation and pulmonary regurgitation severity, most clinical, echocardiographic and humoral parameters were not worse in the second decade after repair of ToF. These data suggest that very early pulmonary valve replacement may not be of benefit.


[1] ToF = tetralogy of Fallot

[2] BNP = B-type natriuretic peptide

[3] RV = right ventricle

[4] NT-proBNP = N-terminal pro-BNP

Background: Parental knowledge of their child’s heart disease, while often overlooked, contributes to compliance and reduces anxiety. Prior studies have shown that 36% of parental diagnostic descriptions are incorrect.

Objectives: To assess parental knowledge and attitudes among outpatients at a hospital pediatric cardiology clinic.

Methods: Seventy-four families completed a questionnaire in which they described their child’s condition and stated their attitude towards dental hygiene and future prenatal diagnosis.

Results: Eighteen percent of the parents failed to describe their child’s malformation correctly. We found that parental understanding of the heart defect correlated with parental education. Future prenatal diagnosis was considered by 88% of families, and termination of pregnancy by 40%. Only 40% of children were aware of their heart problem. Children of parents who were ignorant about the condition tended to lack knowl­edge themselves. An additional finding was that 68% of Jewish families turn to non-medical personnel for medical advice - an interesting finding not hitherto addressed.

Conclusions: Ignorance of their child’s problem did not correlate with its severity or complexity but rather with parental background: the less educated the parent, the more likely was the problem perceived incorrectly.
