Transcatheter valve treatments are expanding, offering options for high-risk patients. Computed tomography is crucial for planning these procedures, ensuring accurate device selection and risk evaluation.
Area of Science:
- Cardiovascular medicine
- Medical imaging
- Interventional cardiology
Background:
- Transcatheter valve interventions are expanding, providing alternatives for patients unsuitable for surgical valve repair or replacement.
- The increasing variety of devices and their applications necessitates robust procedural planning.
Purpose of the Study:
- To highlight the growing role of transcatheter solutions in treating valve disease.
- To emphasize the importance of computed tomography in planning these minimally invasive procedures.
Main Methods:
- Review of current trends in transcatheter valve technology.
- Discussion of the application of computed tomography in pre-procedural assessment.
Main Results:
- Computed tomography (CT) provides accurate device sizing for transcatheter valve procedures.
- CT enables comprehensive procedural risk assessment, aiding in patient selection and planning.
Conclusions:
- Computed tomography is essential for the continued growth and success of transcatheter valve interventions.
- Accurate imaging facilitates optimal outcomes for patients with valve disease undergoing high-risk procedures.

01:10Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
