Paravalvular leak after transcatheter aortic valve replacement.

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Paravalvular leak (PVL) is a frequent complication following transcatheter aortic valve replacement (TAVR).
• PVL occurs at a higher rate after TAVR compared to conventional surgical aortic valve replacement.
• Emerging data suggest a potential association between PVL and increased late mortality.

Purpose of the Study:

• To consolidate current knowledge on post-TAVR PVL.
• To better understand the incidence, progression, and clinical impact of PVL after TAVR.
• To guide future research on PVL assessment, prevention, and treatment.

Main Methods:

• This is a review article.
• It synthesizes existing literature on paravalvular leak after TAVR.
• Focuses on prevalence, assessment methods, and clinical outcomes.

Main Results:

• PVL is a common complication of TAVR.
• Inconsistent assessment methods and timing complicate understanding of PVL prevalence and severity.
• PVL may be linked to increased late mortality, warranting further investigation.

Conclusions:

• Standardization of PVL assessment is crucial for understanding its true clinical impact.
• Further research is needed to address the prevention and management of PVL post-TAVR.
• PVL remains a significant complication requiring focused research and clinical attention.
