Nineteen-Millimeter Bioprosthetic Aortic Valves Are Safe and Effective for Elderly Patients With Aortic Stenosis

In a series of elderly patients with aortic stenosis who were implanted with 19-mm bioprosthetic valves, long-term follow-up showed significant left ventricular mass regression and peak and mean aortic valve gradient reductions. The use of 19-mm aortic valves is safe and efficacious for elderly patients with a small aortic root.
