Alternative Access for Transcatheter Aortic Valve Replacement: A Comprehensive Review

Area of Science:

• Interventional Cardiology
• Cardiovascular Surgery
• Medical Device Technology

Background:

• Transfemoral access is the standard approach for transcatheter aortic valve replacement (TAVR).
• A significant percentage of patients (up to 21%) require alternative access methods for TAVR due to anatomical or clinical factors.
• Optimal patient selection and procedural success depend on understanding various access routes.

Purpose of the Study:

• To comprehensively review alternative access strategies for TAVR.
• To analyze the available data on different TAVR access routes.
• To present the advantages and disadvantages of each alternative access method.

Main Methods:

• Systematic literature review of studies on TAVR alternative access.
• Analysis of procedural outcomes, complications, and patient selection criteria.
• Comparative assessment of different access techniques.

Main Results:

• The review synthesizes data on various alternative TAVR access routes, including transfemoral, transaxillary, and others.
• Each access route presents unique benefits and challenges regarding feasibility, safety, and efficacy.
• Patient-specific factors significantly influence the choice of optimal TAVR access.

Conclusions:

• Alternative access routes are crucial for expanding TAVR eligibility.
• A thorough understanding of pros and cons for each access method is vital for procedural planning.
• Further research may refine patient selection and optimize outcomes for alternative TAVR access.
