Congenital Heart Disease Clinical Trial
Official title:
Predictors of Aortic Root Dilatation in Tetralogy of Fallot Patients
- To predict vulnerable patients for aortic root dilatation in TOF patients using CT as a reliable imaging modality, thus aiding early intervention, and identifying those who will require strict follow-up. - To assess the prevalence of TOF patients who developed aortic root dilatation, and those who were complicated with dissection, AR, and aneurysm, through collecting data from a large center (Aswan Heart Centre). - To investigate the relationship between age at repair and the diameter of aortic root.

Eligibility | Inclusion Criteria: - All patients with TOF who either underwent or have not yet had surgical correction. - All patients with Fallot-type DORV. - Patients should have survived until discharge and have at least one echocardiography and CT with full data related to one or more anatomic subcomponents of the aortic root, either before surgery or during follow-up, regardless of specific duration post repair. Exclusion Criteria: - Patients who have contraindication for conducting cardiac CT scan. For instance, dye sensitivity, pregnancy, CKD, in addition to patients who have factors that interfere with CT image quality as metallic objects within the chest (e.g. Pacemaker). |

Primary | Aortic root diameters | : Aortic root diameters at four levels:
aortic annulus (AA) sinus of Valsalva (SoV) sinotubular junction (STJ) ascending aorta (AAo). AA will be measured as the inter-commissural distance in the aortic valve, SoV will be measured at the level of maximal diameter on the axial image, STJ will be measured at the level of transitional zone from STJ to AAo, and AAo will be measured at the level of the main pulmonary artery bifurcation. Aortic cross-sectional area will be calculated by p×(diameter/2)2 The largest diameters of each aortic structure as measured based on the chest CT will be re-calculated as z-scores. In our study, "significant dilatation of the aortic structures" is defined as 95% confidence interval (z-score=2) in diameter of each aortic structures. Echocardiography will be performed to check other cardiac deformities, including AR. |
Throughout the study duration, about 1 year | |
Secondary | Aortic valve repair or surgical or transcatheter aortic valve replacement | Throughout the study duration, about 1 year | ||
Secondary | Severity of AR at latest follow-up or before the earliest aortic valve or root intervention. | Throughout the study duration, about 1 year |
