Insights
Cardiac Computed Tomography (CCT) is essential for planning transcatheter valve interventions, guiding patient selection, device choice, and procedural success. This imaging technique offers detailed cardiac structure assessment for minimally invasive heart valve treatments.
Area of Science:
- Cardiology
- Medical Imaging
- Interventional Cardiology
Background:
- Valvular heart disease management has shifted towards less-invasive transcatheter interventions.
- Transcatheter valve interventions are crucial for patients unsuitable for surgery.
- Comprehensive imaging is vital for successful transcatheter valve procedures.
Purpose of the Study:
- To review the role of Cardiac Computed Tomography (CCT) in preprocedural planning for transcatheter valvular interventions.
- To highlight CCT's importance in patient selection and procedural guidance.
- To summarize current evidence on CCT's utility in transcatheter valve therapy.
Main Methods:
- Review of current evidence on CCT in transcatheter valvular interventions.
- Analysis of CCT's role in preprocedural assessment.
- Discussion of CCT's application in patient selection, device selection, and procedural guidance.
Main Results:
- CCT provides high-resolution morphological and structural cardiac data.
- CCT is the primary imaging modality for preprocedural planning of transcatheter valve interventions.
- CCT aids in patient selection, procedural access, device choice, and complication monitoring.
Conclusions:
- Cardiac Computed Tomography is indispensable for the successful planning and execution of transcatheter valve interventions.
- CCT enables detailed assessment crucial for optimizing outcomes in minimally invasive valve procedures.
- The review underscores the critical evidence supporting CCT's role in modern interventional cardiology.
Abstract:
Cardiac Computed Tomography (CCT) has become a reliable imaging modality in cardiology providing robust information on the morphology and structure of the heart with high temporal and isotropic spatial resolution. For the past decade, there has been a paradigm shift in the management of valvular heart disease since previously unfavorable candidates for surgery are now provided with less-invasive interventions. Transcatheter heart valve interventions provide a real alternative to medical and surgical management and are often the only treatment option for valvular heart disease patients. Successful transcatheter valve interventions rely on comprehensive multimodality imaging assessment. CCT is the mainstay imaging technique for preprocedural planning of these interventions. CCT is critical in guiding patient selection, choice of procedural access, device selection, procedural guidance, as well as allowing postprocedural follow-up of complications. This article aims to review the current evidence of the role of CCT in the preprocedural planning of patients undergoing transcatheter valvular interventions.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
