What exactly is TAVI?
TAVI stands for transcatheter aortic valve implantation, a medical procedure aimed at enhancing blood flow in the heart by replacing a malfunctioning aortic valve that fails to open fully.
Alternatively referred to as transcatheter aortic valve replacement (TAVR), both terms denote the identical procedure without any variance. TAVI is the preferred terminology in the UK, while TAVR is more commonly used in the USA.
TAVI represents a routine and typically painless medical intervention. It involves the insertion of a slender, flexible tube known as a catheter into a blood vessel located in either the upper leg or chest. This catheter is carefully directed towards the aortic valve within the heart, facilitating the placement of a replacement valve over the existing one.
