[Multimodal cardiovascular imaging before aortic valve transcatheter replacement]

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Severe calcified aortic valve stenosis is a prevalent valvular heart disease in developed nations.
• Symptomatic patients often face poor outcomes, with many denied traditional surgery due to age, comorbidities, or high surgical risk.

Purpose of the Study:

• To highlight Transcatheter Aortic Valve Implantation (TAVI) as a viable alternative for inoperable patients with severe aortic stenosis.
• To emphasize the importance of pre-procedural cardiac imaging for candidate selection and procedural planning.

Main Methods:

• Patient selection for TAVI based on clinical assessment and cardiac anatomy.
• Utilizing cardiac imaging modalities (echocardiography, CT, MRI) to assess feasibility and identify anatomical challenges.
• Considering alternative access routes (e.g., trans-subclavian, trans-apical) when retrograde approaches are contraindicated.

Main Results:

• TAVI provides a crucial treatment option for elderly patients with severe aortic stenosis deemed high-risk for surgery.
• Cardiac imaging is essential for determining appropriate aortic bioprosthesis size and identifying potential difficulties with standard access.
• Alternative access strategies ensure TAVI can be performed even with challenging vascular anatomy.

Conclusions:

• TAVI is a critical advancement for managing severe aortic stenosis in high-risk and elderly populations.
• Accurate pre-procedural imaging and consideration of alternative access routes are paramount for successful TAVI outcomes.
• This approach expands treatment options for valvular heart disease, improving patient management.
