Catheter-based valve implantations (TAVI/TAVR)

Catheter-based valve implantations, also known as Transcatheter Aortic Valve Implantation (TAVI) or Transcatheter Aortic Valve Replacement (TAVR), is a procedure used to treat a condition called aortic stenosis. This is a condition where the aortic valve in the heart narrows, making it difficult for blood to flow through.

The procedure involves implanting a replacement valve in the aortic valve through a catheter that is inserted through a small incision in the leg or chest. TAVI/TAVR is less invasive than traditional open-heart surgery and is typically recommended for patients who have aortic stenosis and are considered too high-risk for surgery.

Eligibility for TAVI/TAVR depends on several factors including the patient's age, overall health, and the severity of their aortic stenosis.
