Aortic valve replacement in patients with inadequate arterial access



Narrowing of the heart’s aortic valve, known as aortic valve stenosis, is the most common heart valve disease in elderly patients. Diseased peripheral arteries can result in reduced access to the heart, forcing surgeons to resort to more invasive open-heart surgery to replace the valve, a procedure that is often considered too high-risk for elderly patients to endure.


IRP researchers led by Robert J. Lederman, M.D., discovered that the heart could be accessed via a vein instead of through diseased arteries. In a study involving 100 patients, this innovative technique was found to be a successful alternate route for heart valve replacement.


Dr. Lederman’s approach provides a viable alternative for accessing the heart in patients requiring aortic valve replacement, thereby expanding access to patients with peripheral artery disease who otherwise might have no good options.
