Multimodal Imaging Evaluation of Aortic Stenosis.

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Transthoracic echocardiography (TTE) is the primary diagnostic tool for aortic stenosis (AS).
• Discordant or inadequate TTE findings necessitate alternative imaging modalities for accurate AS severity assessment.
• Multimodality imaging aids in determining prognosis and guiding patient management in AS.

Purpose of the Study:

• To discuss the role of multimodality imaging in the accurate diagnosis of AS severity.
• To highlight the importance of multimodality imaging in assessing prognosis for AS patients.
• To provide an overview of computed tomography (CT) for transcatheter aortic valve replacement (TAVR) procedural planning.

Main Methods:

• Review of current literature on multimodality imaging in aortic stenosis.
• Discussion of TTE, and alternative modalities like CT and MRI.
• Focus on the application of imaging in diagnosis, prognosis, and TAVR planning.

Main Results:

• Multimodality imaging is crucial for confirming AS severity when TTE is inconclusive.
• Imaging findings correlate with patient prognosis and influence management decisions.
• CT is valuable for pre-procedural assessment in TAVR candidates.

Conclusions:

• Multimodality imaging is essential for comprehensive AS evaluation.
• Accurate diagnosis and prognostic assessment through advanced imaging improve patient care.
• CT plays a significant role in planning TAVR procedures.
