Multidetector computed tomography in transcatheter aortic valve replacement: an update on technological developments...

Area of Science:

• Cardiovascular Imaging
• Interventional Cardiology

Background:

• Transcatheter aortic valve replacement (TAVR) has transformed severe aortic valve stenosis treatment.
• CT imaging is essential for pre-procedural planning, intraprocedural decision-making, and post-procedural complication management in TAVR.

Purpose of the Study:

• To review current studies on the role of CT imaging in TAVR procedures.
• To provide updates on technological advancements and clinical applications of CT in TAVR.

Main Methods:

• Review of available scientific literature on CT imaging in TAVR.
• Analysis of technological developments and clinical applications.

Main Results:

• CT imaging offers high resolution crucial for aortic annular measurements and bicuspid aortic valve assessment.
• CT aids in identifying hypoattenuated leaflet thickening and is vital for valve-in-valve therapy.
• CT imaging facilitates the study of aortic stenosis mechanisms and detection of high-risk anatomy.

Conclusions:

• CT imaging is the ideal approach for accurate risk stratification in TAVR patients.
• CT enables personalized, catheter-based interventions for severe aortic valve stenosis.
• Advancements in CT technology enhance its utility in TAVR procedures.
