Transcatheter aortic valve implantation in 2026

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Technology

Background:

• Transcatheter aortic valve implantation (TAVI) has evolved into a standard treatment for severe aortic stenosis.
• Evidence supports TAVI for high, intermediate, and increasingly lower-risk patients.
• Technological advancements and operator experience have improved TAVI safety and efficacy.

Purpose of the Study:

• To provide an updated review of transcatheter aortic valve implantation (TAVI).
• To discuss key areas of development, including patient selection, imaging, and coronary access.
• To address challenges such as conduction disturbances, paravalvular leak, and long-term valve durability.

Main Methods:

• Literature review of recent landmark trials and European Society of Cardiology guidelines.
• Synthesis of current evidence on TAVI patient selection and imaging modalities.
• Analysis of challenges and future directions in TAVI management.

Main Results:

• TAVI is increasingly utilized across a broader spectrum of patients.
• Operator experience and technology have significantly reduced procedural risks.
• Persistent challenges include coronary access, conduction disturbances, paravalvular leak, and cost-effectiveness.

Conclusions:

• TAVI is a well-established treatment for severe aortic stenosis, expanding to lower-risk populations.
• Ongoing research and technological innovation are crucial for addressing remaining TAVI challenges.
• Lifetime management strategies and long-term valve durability are critical for future TAVI success.
