Key result
Multi-slice computed tomography assessment of the aortic annulus yielded a mean diameter of 26.3 ± 2.3 mm in coronal view, compared to 22.1 ± 2.5 mm measured by echocardiography.

Cardiac CT provides valuable complementary measurements to echocardiography for optimum positioning of the aortic valve during TAVI.
For better approach and optimum benefit from cardiac CT in pre-procedural assessment of the transcatheter aortic valve implantation (TAVI). 120 patients underwent cardiac CT examination and echocardiography for preoperative assessment of the aortic root measurements and vascular root evaluation. In coronal view, the mean diameter of the aortic annulus was 26.3 ± 2.3 mm while in single oblique sagittal view it was 23.9 ± 2.0 mm. Mean Agatston score of aortic calcifications was 786 ± 1324. The mean diameter of the aortic annulus by echocardiography was 22.1 ± 2.5 mm. Cardiac CT is considered a valuable approach for optimum positioning of the aortic valve in conjunction with echocardiography to avoid undesirable complications and reducing the mortality rate.

M. Mourad (2016) conducted an observational in Pre-procedural assessment for transcatheter aortic valve implantation (TAVI) (n=120). Multi-slice computed tomography (MSCT) vs. Echocardiography was evaluated on Aortic annulus diameter. Multi-slice computed tomography assessment of the aortic annulus yielded a mean diameter of 26.3 ± 2.3 mm in coronal view, compared to 22.1 ± 2.5 mm measured by echocardiography.
