The UnityPoint Health Cedar Rapids Heart & Vascular Institute offers Transcatheter Aortic Valve Replacement (TAVR). This procedure is for patients that are high risk or too sick for open-heart surgery. Transcatheter aortic valve replacement, or TAVR is a less invasive procedure that does not require open-heart surgery. This procedure involves a multi-disciplinary team of physicians from UnityPoint Health Cardiology Clinic and Physicians' Clinic of Iowa Surgical Specialists.
The TAVR procedure offers hope for heart patients with inoperable aortic stenosis (failing heart valves), that are not candidates for surgical valve replacement. TAVR valves are inserted via a catheter through the femoral artery, without requiring open-heart surgery. This minimally invasive surgical procedure repairs the damaged valve by placing a replacement valve into the aortic valve. Somewhat similar to a stent placed in an artery; this approach delivers a fully collapsible replacement valve to the valve site through a catheter. Left untreated, aortic valve stenosis can lead to serious heart problems.
Aortic stenosis affects three percent of persons older than 65 and is a common heart problem caused by a narrowing of the heart's aortic valve due to excessive calcium deposited on the valve leaflets. When the valve narrows, it does not open or close properly, making the heart work harder to pump blood throughout the body. Eventually, this causes the heart to weaken and function poorly, which may lead to heart failure and increased risk for sudden cardiac death. Nearly 16 percent of Iowa's population is 65 or older and that number is expected to increase 20 percent of the state's population by 2050. A study from the Journal of the American College of Cardiology finds these patients with mild to severe aortic stenosis stand to benefit greatly from this minimally invasive TAVR procedure.
