Clinical trials in transcatheter aortic valve replacement

Area of Science:

• Cardiovascular medicine
• Interventional cardiology
• Medical device technology

Background:

• Transcatheter aortic valve replacement (TAVR) has emerged as a disruptive technology in treating aortic valve disease.
• Ongoing clinical trials are crucial for understanding TAVR's effectiveness and limitations.

Purpose of the Study:

• To review recent and ongoing clinical trials in TAVR.
• To discuss future TAVR trial directions and emerging technologies.

Main Methods:

• Focus on clinical trials presented in the past year or currently enrolling.
• Analysis of device iterations and their impact on safety and outcomes.
• Consideration of trials for intermediate-risk and low-risk patient populations.

Main Results:

• Device improvements have reduced complications like bleeding and para-valvular regurgitation.
• Intermediate-risk trials are nearing completion, with low-risk trials commencing.
• Ancillary devices are expanding TAVR accessibility.

Conclusions:

• Recent advancements in TAVR devices have led to better patient outcomes.
• Current and future trials are expanding TAVR to lower-risk patients and exploring new platforms.
• Post-TAVR pharmacotherapy remains a key area for future research and challenges.
