Transcatheter Aortic Valve Replacement in Special Population Groups.

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Transcatheter aortic valve replacement (TAVR) has transformed severe symptomatic aortic stenosis treatment across all surgical risk categories.
• TAVR's application has expanded to unique populations, including those with active malignancies, psychiatric disorders, and advanced organ dysfunction, who were previously underrepresented in clinical trials.

Purpose of the Study:

• To evaluate the safety, efficacy, and appropriateness of TAVR in special patient populations.
• To identify specific challenges associated with TAVR implantation in these unique clinical groups.

Main Methods:

• Comprehensive literature review of current studies on TAVR in special patient populations.
• Analysis of existing data regarding outcomes and procedural considerations.

Main Results:

• TAVR demonstrates feasibility and acceptable outcomes in patients with active malignancies, psychiatric disorders, and advanced organ dysfunction.
• Specific challenges include managing comorbidities, multidisciplinary care coordination, and patient selection.

Conclusions:

• TAVR is a viable option for selected patients with severe aortic stenosis and unique clinical considerations.
• Further research is needed to optimize TAVR strategies and outcomes in these underrepresented groups.
