Dual-source CT with metal sphere-tube for preoperative evaluation of patients with aortic valve disease treated by transcatheter aortic valve implantation

Abstract

To predict the effects of Dual-source CT imaging technology for preoperative patients with transcatheter aortic valve implantation. This is a parallel, randomly allocated to following two groups: patients with the Dual-source CT imaging technology and with conventional imaging technology, and the clinical material from two groups patients with Aortic valve disease are collected, and the images quality between two group are assessed and then complications in one month after surgery are recorded by follow-up. Our outcomes show that patients by the Dual-source CT imaging technology show less complications compared to patients by conventional imaging technology and imaging quality is better than that in conventional imaging group. In addition, image noise, and contrast-to-noise ratio are also examined by Dual-source CT imaging. We can conclude that the Dual-source CT can effectively reduce the complications, and the Dual-source CT can predict effects of preoperative patients with Aortic valve disease and prevent the development of Aortic valve disease (AVD).
