Types of Transcatheter Aortic Valve Replacement (TAVR)
Transcatheter aortic valve replacement (TAVR) is a newer, minimally invasive approach for treating aortic valve disease. The TAVR procedure has expanded the possibilities for replacing the aortic valve, and we continue to help shape its evolution.
TAVR Valve types - wikidoc
There are currently 8 prosthetic transcatheter valve types which are available. Two of these are FDA approved in the United States. [1] The CHOICE trial is a small study which compared the most prominent two valves (CORE and SAPIEN) and no major significant differences were found in primary clinical endpoints between both valves.

2023年9月28日 · The two predominant types of commercially available TAVR valves are balloon-expandable valves and self-expanding valves. Self-expanding valves provide a larger effective orifice area and lower gradient, particularly those valves with a supra-annular design, but they tend to be associated with a greater need for new pacemaker implantation, as ...
TAVR - FAQ's Answered by a Cardiologist - myheart.net
2015年6月30日 · There are two main types of TAVR valves, balloon-expandable and self-expandable. In the balloon expandable type, the compressed valve is mounted on a balloon. When the balloon-expandable TAVR valve is in the correct position the balloon is inflated, enlarging the valve in the process to its normal working size.
Types of TAVR Valves – Which Valve is better? | Dr. C Raghu
TAVR valves are of two types: Balloon expandable valve; Self-expanding valve; In India both these types of valves are available from different manufacturers. Balloon expandable valve types: Edwards valve: The first balloon expandable valve was developed by the Edwards Company where you have got the Edwards 3 model of the valve. So this is a ...
TAVI: Which Valve for Which Patient? - Cardiac Interventions Today
There is now a wide range of commercially available transcatheter aortic heart valves with which clinicians can treat their patients. These valves significantly differ in their design, construction, and mechanism.
Transcatheter aortic valve replacement (TAVR) is a safe treatment for some people who have aortic stenosis (AS), a narrowing of the aortic valve opening in the heart. The Regional Heart Center at UWMC was one of the very first sites in the U.S. to do TAVR, as part of a study called the PARTNER trial.
Transcatheter aortic valve replacement (TAVR) - Mayo Clinic
Transcatheter aortic valve replacement (TAVR) is a type of heart valve surgery. It's done to replace a narrowed aortic valve, a condition called aortic valve stenosis. A doctor inserts a flexible tube called a catheter into a blood vessel and guides it into the heart.
