Transcatheter aortic valve replacement (TAVR) procedures were introduced in the early
2000s as an alternative to surgical aortic valve replacement (SAVR) in high-risk patients
who were not surgical candidates.
1
The safety of the procedure improved over time as the procedure became more widespread
and new deployment devices, valves, and percutaneous access were refined.
1
Encouraging outcomes, such as a decreased hospital length of stay and improved morbidity,
have expanded access to TAVRs to populations deemed intermediate and low-risk for
SAVR.

According to the Society of Thoracic Surgery-American College of Cardiology Transcatheter
Valve Therapy Registry, >70,000 TAVRs were performed in the United States in 2019,
surpassing the number of SAVRs that year.
2
The most common access site is increasingly transfemoral (95% in 2019), and the need
for conversion to open cardiac surgery with the use of cardiopulmonary bypass has
significantly decreased from 4% to 0.4% since the introduction of TAVRs.
2
The focus of care surrounding TAVRs is now shifting to a minimally invasive approach
with shorter procedure time, shorter hospital length of stay, and reduced costs.

Although both conscious sedation and general anesthesia techniques can be used for
TAVR procedures, the authors assert that conscious sedation is superior as it helps
achieve these goals with potentially less risk.To read this article in full you will need to make a payment
