Computed tomography to guide transcatheter aortic valve implantation

Area of Science:

• Cardiovascular Medicine
• Medical Imaging
• Interventional Cardiology

Background:

• Transcatheter aortic valve implantation (TAVI) has transformed aortic stenosis management since 2022.
• Clinical evidence confirms TAVI's efficacy and safety in improving patient prognosis.

Purpose of the Study:

• To highlight the critical role of preprocedural imaging in TAVI success.
• To emphasize computed tomography (CT) as the standard for patient assessment in TAVI.

Main Methods:

• Computed tomography (CT) is utilized for comprehensive preprocedural planning.
• CT assesses suitability for transfemoral access, aortic annulus dimensions, and coronary ostia relationships.

Main Results:

• CT provides essential data for prosthesis selection and implantation guidance.
• Key information includes vessel suitability, annular geometry, and coronary artery proximity.

Conclusions:

• Preprocedural CT is indispensable for successful TAVI.
• Ongoing research focuses on refining risk stratification for TAVI complications.
