A Brief of Heart valve Scan by CT Scan Medical Imaging

Author(s): Feuchtner Gudrun

This article describes "how" to examine heart valves with computed tomography, normal, diseased, and prosthetic valves. A review of the current scientific literature is proposed. First, the technical basics, "how" to perform and optimize multi-slice CT, and "how" to interpret valves on CT images are described. Next, full-spectrum imaging of specific valve disease by CT, including prosthetic heart valves, is emphasized. The final section provides "how" guidance on using computed tomography to plan Trans Catheter Aortic Valve Implantation (TAVI), an emerging effective treatment option for patients with arterial stenosis. Heavy owner Particular emphasis is placed on the clinical applications of cardiac CT in the context of valvular disease. Multi-slice Computed Tomography (CT) is a new noninvasive evaluation modality of heart valves, with new clinical applications emerging in recent years. While multi slice computed tomography has been established to evaluate coronary arteries for a decade, the original heart valve has been overlooked. One of the reasons is that echocardiography is such an important modality in clinical practice. However, it has its own limitations, such as with regard to observer variability and high inter-individual variation in image quality depending on body habits or dependence from its throughput. In addition, echocardiography has limitations in assessing valve morphology. Therefore, multimodal imaging, including computed tomography, is essential for the diagnosis of valvular heart disease.
