| Transcatheter aortic valve replacement : Transcatheter aortic valve replacement (TAVR) is a procedure used to replace the aortic valve without opening the chest. It is used to treat adults who aren't healthy enough for regular valve surgery. The aorta is a large artery that carries blood from your heart to the rest of your body. Blood flows out of your heart and into the aorta through a valve. This valve is called the aortic valve. It opens up so blood can flow out. It then closes, keeping blood from flowing backwards. An aortic valve that does not open fully will restrict blood flow. This is called aortic stenosis. If there is also a leak that lets blood go back across the aortic valve, it is called aortic regurgitation. Most aortic valves are replaced because they restrict flow forward through the aorta to the brain and body. | |
