Outline of Final Research Achievements

Transcatheter aortic valve implantation (TAVI) is considered an effective treatment option for patients with severe and symptomatic aortic valve stenosis not suitable for conventional valve replacement. Multi-detector row computed tomography (CT) has become the standard non-invasive imaging method in pre-TAVI assessment for aortic root dimensions and access site. To ensure technical success and optimal valve-prosthesis sizing, a dedicated scan technique is of utmost importance. However, optimal scan protocol for pre-TAVI assessment has not been fully established. We have developed the optimal scan protocol based on our phantom and clinical studies corresponding to individual patients. The scan techniques enable the high-precision pre-TAVI measurement using a three-dimensional automatic measurement software. This is helpful for safe and appropriate management in patinet with aortic valve stenosis.
