Low risk TAVR: Long- term considerations and appropriate patient selection

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Transcatheter Aortic Valve Replacement (TAVR) has demonstrated excellent short-term outcomes in low-risk patients, including low complication rates and mortality.
• This success has led to expanded FDA indications for TAVR in this patient population.
• However, long-term data regarding valve durability, subclinical leaflet thrombosis, and pacemaker-related issues remain limited.

Purpose of the Study:

• To review clinical and procedural considerations for selecting low-risk patients for TAVR.
• To identify potential future challenges associated with TAVR procedures.
• To emphasize the importance of life expectancy and valve durability in the decision-making process for TAVR.

Main Methods:

• Review of recent clinical trial data on TAVR in low-risk populations.
• Discussion of clinical and procedural factors influencing patient selection.
• Analysis of potential long-term sequelae and future procedural considerations.

Main Results:

• TAVR in low-risk patients is associated with low complication rates, short hospital stays, and excellent short-term survival.
• Significant uncertainties persist regarding long-term valve performance, including thrombosis and durability.
• The impact of pacemaker implantation and right ventricular pacing on outcomes needs further investigation.

Conclusions:

• While TAVR is a viable option for low-risk patients, careful consideration of long-term outcomes is essential.
• Patient selection should incorporate life expectancy and the expected durability of the aortic valve prosthesis.
• A multidisciplinary heart team approach is critical for optimizing TAVR patient management and outcomes.
