The association between wedging of the aorta and cardiac structural anatomy as revealed using multidetector‐row computed tomography
The aortic root is wedged within the cardiac base. The precise extent of aortic wedging, however, and its influence on the surrounding cardiac structures, has not been systematically investigated. We analysed 100 consecutive patients, who underwent coronary arterial computed tomographic angiography....

| description | The aortic root is wedged within the cardiac base. The precise extent of aortic wedging, however, and its influence on the surrounding cardiac structures, has not been systematically investigated. We analysed 100 consecutive patients, who underwent coronary arterial computed tomographic angiography. We assessed the extent of aortic wedging by measuring the vertical distance between the non‐adjacent aortic sinus and the inferior epicardium. A shorter distance indicates deeper aortic wedging. We assessed the tilt angle and diameter of the ascending aorta, the relative heights of the left atrial roof and the oval fossa, the shape of the proximal right coronary artery, the angle of the aorta relative to the left ventricular axis, and the lung volume. The mean extent of wedging was 42.7 ± 9.8 mm. Multivariate analysis revealed that ageing, male gender, increased body mass index, patients without cardiomyopathy, the extent of tilting and dilation of the ascending aorta, and lung volume were all independent predictors for deeper aortic wedging (R2 = 0.7400, P |

The extent of wedging was additionally correlated with a relatively high left atrial roof (R2 = 0.1394, P < 0.0001) and oval fossa (R2 = 0.1713, P < 0.0001), the shepherd's crook shape of the proximal right coronary artery (R2 = 0.2376, P < 0.0001), and the narrowness of the angulation of the root relative to the left ventricular axis (R2 = 0.2544, P < 0.0001).
