Obesity and Transcatheter Aortic Valve Replacement.

Area of Science:

• Cardiovascular Medicine
• Obesity Research
• Interventional Cardiology

Background:

• Aging populations and rising obesity rates necessitate understanding obesity's impact on TAVR.
• The
• obesity paradox
• suggests better outcomes for obese TAVR patients, contrary to general cardiovascular risk.
• Investigating this paradox is crucial for patient management.

Purpose of the Study:

• To comprehensively review the relationship between obesity and TAVR outcomes.
• To specifically analyze the impact of obesity on TAVR-related mortality and periprocedural complications.
• To explore the mechanisms behind the obesity paradox in TAVR.

Main Methods:

• Literature review focusing on obesity and TAVR outcomes.
• Analysis of studies reporting mortality and complication rates in TAVR patients across different BMI categories.
• Synthesis of evidence regarding the obesity paradox in this specific patient population.

Main Results:

• The review indicates a complex association between obesity and TAVR outcomes.
• Evidence suggests a potential survival benefit for obese patients undergoing TAVR, aligning with the obesity paradox.
• Further research is needed to clarify the extent and mechanisms of this association.

Conclusions:

• Obesity's role in TAVR outcomes, particularly the obesity paradox, requires further investigation.
• Understanding these dynamics can help optimize TAVR strategies for diverse patient profiles.
• Tailored management approaches may improve TAVR success rates in obese individuals.
