Abstract
Background: Congenital heart disease (CHD) is the most common neonatal anomaly. Extracardiac findings are commonly associated with CHD. It is mandatory to evaluate extracardiac structures for potential associated abnormalities that might impact the surgical planning for these patients. The purpose of this study was to determine the extracardiac abnormalities that could associate cardiac anomalies and to give insights into their embryological aberrations.
Results: Thirty-two pediatric patients (22 males and 10 females) underwent CT angiography to assess CHD. Diagnosis of the CHD and associated extracardiac findings were recorded and tabulated by organ system and type of CHD.
Retrospective ECG-gated low-peak kilovoltage (80Kvp) technique was used on 128MDCT GE machine. Patients were diagnosed according to their CHD into four groups: chamber anomalies 90%, septal anomalies 81.3%, conotruncal anomalies 59.4%, and valvular anomalies 59.4%. Extracardiac findings were found in 28 patients (87.5%) with a total of 76 findings. Vascular findings were the most prevalent as 50 vascular findings were observed in 28 patients. Aortic anomalies were the commonest vascular anomalies. Fourteen thoracic findings were observed in 12 patients; of them lung consolidation patches were the most common and 12 abdominal findings were found in seven patients, most of findings were related to situs abnormalities.
Conclusion: Extracardiac abnormalities especially vascular anomalies are commonly associating CHD. Along with genetic basis, aberrations in dynamics of blood flow could represent possible causes of this association.
