Supports equivalent use of either valve in small annuli; extends RCT evidence of no hemodynamic or clinical superiority.
Does the St. Jude Medical valve improve clinical and echocardiographic outcomes compared to the Medtronic Hall valve in patients with small aortic annuli requiring aortic valve replacement?
There is no significant difference in clinical or echocardiographic performance between St. Jude Medical and Medtronic Hall valves when used for aortic valve replacement in patients with small aortic annuli.
