Summary
Transcatheter aortic valve replacement (TAVR) is a leading treatment for aortic stenosis, now benefiting younger patients and complex anatomies. Innovations enhance TAVR safety and efficacy, though challenges persist.
Area of Science:
- Cardiology
- Interventional Cardiology
- Biomedical Engineering
Background:
- Aortic stenosis is the most common global valvular heart disease.
- Transcatheter aortic valve replacement (TAVR) offers outcomes comparable to surgical aortic valve replacement (SAVR).
- TAVR is increasingly used in younger, lower-risk patients and those with complex anatomies.
Purpose of the Study:
- To review recent advancements in transcatheter heart valve (THV) systems.
- To highlight innovations in TAVR technology and devices.
- To discuss current limitations and challenges in TAVR procedures.
Main Methods:
- Review of recent literature on TAVR advancements.
- Analysis of new transcatheter heart valve (THV) systems.
- Examination of leaflet modification devices and TAVR limitations.
Main Results:
- Transfemoral access is more common.
- Prosthesis designs are optimized for challenging anatomies.
- Enhanced delivery systems offer repositioning, and outer skirts reduce paravalvular leaks.
Conclusions:
- TAVR technology continues to evolve rapidly.
- Innovations are expanding TAVR applicability and improving patient outcomes.
- Addressing remaining challenges is crucial for further TAVR adoption and success.
