Abstract

Objective: This study aims to evaluate clinic situations, investigate arrhythmias, and assess ventricle function by echocardiography and aortic root dilation of patients with Tetralogy of Fallot who had undergone total correction surgery.


Material and Methods: 50 children with Tetralogy of Fallot and who had undergone a total correction operation in I.U. Faculty of Medicine Pediatric Cardiology Department were included to study. Corrected Tetralogy of Fallot cases were divided into two main groups as “aortic root dilated group” and “aortic root not-dilated group”. Groups were evaluated as to their gender, age of correction surgery, presence of aortic failure, tricuspid failure, pulmonary failure, aorta pulmonary shunt treatment and usage of transannular patch. Pulmonary valve failure was compared as those with and without transannular patches applied during the total correction surgery. Echocardiographically measured aortic root and ascending aorta diameters were assessed according to age, gender, and body surface area of the corrected Fallot Tetralogy cases.


Results: 50 subjects were involved to study in date between 24th Jan. 2014 and 15th May 2014. Age of the cases in study varied between 2 and 21 years and average age was 9.9 ± 4.5 years. 52% (n=26) of them are male and 48% are female (n=24). Total correction age was varied between 6 months (0.5 years) and 190 months (15.8 years) and average age was 28.3±28.3 months (2.3 ±2.3 years). Their postoperative periods were varied between 1.3 and 17.8 years and average period was 8.0±4.1 years. 28% (n=14) of the cases were received palliative treatment. Aortic root size was varied between 18 and 42.5 and average size was measured as 27.9±5.3 mm. Aortic root dilation ratio of the cases was 88% (n=44) while 12% of cases (n=6) had no aort root dilatation. All patients had right ventricle and ascending aorta dilation. Moderate and severe pulmonary failure was found less in those who underwent transannular patch.

Conclusion: Aortic root dilation was detected in 88% (n=44) of the cases. Providing annual aortic root diameter measurements will help to plan a more effective strategy for the treatment of progressive aortic root dilatation in patients with Fallot tetralogy.
