Exploring Optimal Strategies for Surgical Access in Transcatheter Aortic Valve Implantation

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology

Background:

• Severe aortic stenosis management has been transformed by Transcatheter Aortic Valve Implantation (TAVI).
• The transfemoral approach is standard for TAVI due to its minimally invasive benefits and faster recovery.
• Anatomical limitations can prevent transfemoral access in 80-90% of TAVI cases.

Purpose of the Study:

• To review alternative surgical access techniques for Transcatheter Aortic Valve Implantation (TAVI).
• To explore the rationale, technical aspects, and challenges of non-transfemoral TAVI access routes.

Main Methods:

• Comprehensive literature review of TAVI access strategies.
• Analysis of alternative TAVI access routes including transapical, transaortic, transaxillary, and transcarotid approaches.

Main Results:

• Transfemoral access is feasible in 80-90% of TAVI procedures.
• Anatomical constraints necessitate alternative access in a subset of patients.
• Various alternative TAVI access routes exist, each with specific benefits and limitations.

Conclusions:

• Alternative access routes are essential for TAVI when transfemoral access is contraindicated.
• Understanding the technical nuances of each alternative TAVI approach is critical for successful valve implantation.
• Further research may optimize patient selection and outcomes for alternative TAVI access strategies.
