What is transcatheter aortic valve replacement (TAVR)?

Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure specifically designed to replace a narrowed aortic valve, which is a condition known as aortic stenosis. During this procedure, a new valve is inserted through a small incision, typically in the groin, and guided to the heart using a catheter. This approach reduces the need for open-heart surgery and can significantly minimize recovery time and complications for patients who may be considered high risk for traditional surgery.

TAVR is not simply a repair of the aortic valve, as option A suggests, because it involves replacing the valve entirely rather than just fixing it. Furthermore, it is not an emergency treatment for heart attack (option C) nor a medication to manage atrial fibrillation (option D). TAVR specifically targets aortic valve issues and offers a viable solution for those suffering from severe aortic stenosis, enhancing their quality of life and overall outcomes.
