Insights
Transcatheter aortic valve replacement (TAVR) improves outcomes for severe aortic stenosis patients. This review guides radiologists on using multimodality imaging effectively throughout the TAVR procedure, from planning to follow-up.
Area of Science:
- Cardiology
- Radiology
- Medical Imaging
Background:
- Aortic stenosis (AS) is a prevalent valvular heart disease.
- Symptomatic AS carries a high mortality risk, necessitating prompt intervention.
- Transcatheter aortic valve replacement (TAVR) offers improved outcomes for high-risk patients with severe AS.
Purpose of the Study:
- To provide radiologists with an evidence-based approach to multimodality imaging in TAVR.
- To outline the indications, strengths, and limitations of various imaging modalities across TAVR stages.
Main Methods:
- Review of current literature on imaging modalities used in TAVR.
- Discussion of pre-procedural planning, intra-procedural guidance, and post-procedural follow-up imaging.
Main Results:
- Multimodality imaging is crucial for successful TAVR outcomes.
- Understanding specific imaging modality roles optimizes patient care.
- Radiologists require comprehensive knowledge of imaging techniques for TAVR.
Conclusions:
- This review offers a framework for radiologists to navigate imaging in TAVR.
- Effective use of imaging modalities enhances TAVR procedure success and patient safety.
Rationale And Objectives:
Aortic stenosis (AS) is one of the most common valvular heart disease. Symptomatic AS is associated with a high mortality rate which prompts fast intervention. The introduction of transcatheter aortic valve replacement (TAVR) has drastically improved the outcome of high surgical risk for mortality patients with severe AS. However, this procedure requires the employment of multimodality imaging in the pre-procedural planning, intra-procedural optimization, and post-procedural follow-up stages. This also requires an accurate understanding of the indications, measurements, strength, and limitations of each imaging modality during the different TAVR stages.
Conclusion:
In this review, we aim to outline to radiologists the evidence-based approach and indications of different imaging modalities through the pre, peri, and post TAVR stages.

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...
