TAVR (tÄv-er), is a heart procedure that does not require open-heart surgery. It provides a new aortic valve to patients with aortic valves that do not work properly. During the TAVR procedure, a new heart valve made from bovine (cow heart) tissue is collapsed and guided via a catheter to the patientâs aortic valve. Once the new valve is positioned inside of the patientâs own aortic valve, it is opened to restore blood flow to the body. Bronson Methodist Hospital is the only hospital in southwest Michigan qualified to offer four approaches to TAVR: Transaortic, through a small incision on the upper right side of the chest.
