Summary
Transcatheter aortic valve implantation (TAVI) has improved, but complications like regurgitation and stroke persist. This review covers TAVI complications, focusing on patient selection, valve issues, and adverse events.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Device Technology
Background:
- Transcatheter aortic valve implantation (TAVI) offers improved safety and efficacy with advancements.
- Despite progress, significant procedural complications remain a concern in TAVI.
Purpose of the Study:
- To review the pathophysiology, avoidance strategies, and treatment options for TAVI complications.
- To address current hot topics in TAVI, including patient selection and device-related issues.
Main Methods:
- Literature review of current research on TAVI complications.
- Analysis of pathophysiology, clinical presentation, and management strategies.
Main Results:
- Key complications include paravalvular regurgitation, cerebrovascular accidents, and pacemaker requirement.
- Optimized patient selection and valve sizing are crucial for minimizing risks.
- Effective management strategies exist for vascular complications and other adverse events.
Conclusions:
- While TAVI technology and experience have advanced, vigilance for complications is essential.
- Addressing patient selection, valve sizing, and specific adverse events can further enhance TAVI outcomes.
