Renal dysfunction and transcatheter aortic valve implantation outcomes

Area of Science:

• Cardiology
• Nephrology

Background:

• Transcatheter aortic valve implantation (TAVI) is evolving as a primary treatment for severe aortic stenosis, particularly for inoperable and high-risk patients.
• Chronic kidney disease (CKD) is a common comorbidity in TAVI candidates, significantly affecting prognosis.
• Acute kidney injury (AKI) following TAVI is a frequent complication linked to increased mortality.

Purpose of the Study:

• To review the current understanding of pre-procedural CKD and post-procedural AKI in patients undergoing TAVI for severe aortic stenosis.
• To highlight the prognostic implications of kidney disease in TAVI patients.

Main Methods:

• This is a review article discussing existing knowledge on kidney disease and TAVI.
• Literature search and synthesis of current evidence regarding CKD and AKI in TAVI.

Main Results:

• Pre-procedural CKD is a significant predictor of worse short- and long-term outcomes in TAVI patients.
• Post-procedural AKI is associated with increased mortality and adverse clinical events.
• Both CKD and AKI represent critical factors influencing TAVI success.

Conclusions:

• Kidney function assessment and management are crucial for optimizing TAVI outcomes.
• Future research should focus on risk stratification, complication prevention, and post-TAVI management strategies for kidney disease.
• Improving the care of TAVI patients with CKD and preventing AKI are essential for better clinical results.
