Approach of multi-slice computed tomography (MSCT) in assessment of transcatheter aortic valve implantation (TAVI)

ObjectivesFor better approach and optimum benefit from cardiac CT in pre-procedural assessment of the transcatheter aortic valve implantation (TAVI).Materials and methods120 patients underwent cardiac CT examination and echocardiography for preoperative assessment of the aortic root measurements and vascular root evaluation.ResultsIn 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.ConclusionCardiac 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.
