入选标准
- •All patients who underwent Ross procedure with loose jacket technique at Aswan Heart Centre, regardless of the indication and duration after surgery.
- •Patients should have survived until discharge and underwent at least one echocardiography with full data related to one or more anatomic subcomponents of the aortic root before surgery.
排除标准
- •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).
- •Patients who have contra-indication for conducting a safe MRI scan. For instance, metallic implants that are incompatible with MRI.
- •Patients who underwent Ross procedure with technique other than loose jacket.
结局指标
主要结局
Accuracy of MRI measurements in comparison to CT using statistical analysis.
时间窗: 1 year
We will use bland altman plots to visualize the degree of agreement between the two raters and identify any systematic bias. The closer the difference to zero, the better.
次要结局
- The largest diameters of each aortic structure(1 year)
