Transcatheter Aortic Valve Replacement for Aortic Regurgitation: A Case-Based Review

Area of Science:

• Cardiology
• Interventional Cardiology
• Valvular Heart Disease

Background:

• Aortic regurgitation (AR) is a common valvular heart disease, increasing with age.
• Surgical aortic valve replacement is standard but often deferred due to high surgical risk, leaving many severe AR patients untreated.
• Transcatheter aortic valve replacement (TAVR) is a less invasive alternative, but off-label use faces challenges.

Purpose of the Study:

• To review the evolving role of TAVR in treating aortic regurgitation.
• To highlight practical considerations for TAVR in AR using patient vignettes.
• To discuss device selection, anchoring, and complication management in TAVR for AR.

Main Methods:

• Case-based review utilizing three patient vignettes.
• Discussion of device selection and anchoring strategies for TAVR in AR.
• Exploration of complication management in TAVR for AR.

Main Results:

• Dedicated TAVR devices have improved procedural success for AR by addressing anchoring difficulties.
• Patient vignettes illustrate key considerations in TAVR for AR.
• Outcomes with dedicated TAVR systems for AR are encouraging.

Conclusions:

• TAVR is an evolving treatment option for aortic regurgitation, particularly in high-risk patients.
• Dedicated TAVR devices demonstrate improved efficacy and safety for AR.
• Further research and device innovation are necessary to establish TAVR as a standard treatment for AR and improve patient outcomes.
