Revascularization in the Transcatheter Aortic Valve Replacement Population

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Transcatheter aortic valve replacement (TAVR) is a primary treatment for severe aortic stenosis.
• Management of concurrent coronary artery disease (CAD) in TAVR patients lacks definitive guidance from randomized trials.
• Defining and assessing CAD in this population presents challenges due to heterogeneity.

Purpose of the Study:

• To review the rationale and prognostic significance of coronary artery disease (CAD) in patients undergoing transcatheter aortic valve replacement (TAVR).
• To explore the complexities surrounding the management of concomitant CAD in the context of TAVR.
• To highlight the individualized approach to coronary revascularization decisions by heart teams.

Main Methods:

• Literature review and discussion of existing evidence.
• Analysis of the prognostic role of CAD in TAVR candidates.
• Examination of diagnostic and definitional heterogeneity of CAD.

Main Results:

• The role and impact of CAD in TAVR patients are not fully elucidated.
• Current decision-making for coronary revascularization is individualized.
• Lack of standardized methods for CAD assessment complicates evaluation.

Conclusions:

• The prognostic implications of CAD in TAVR patients warrant further investigation.
• A case-by-case assessment by heart teams is crucial for managing concomitant CAD.
• Future research is needed to standardize CAD assessment and guide treatment strategies.
