Medtronic plc reported positive interim results on the first 171 patients implanted with Evolut transaortic valve replacement (TAVR) devices in its OPTIMIZE PRO clinical trial. The postmarket, prospective, multicenter study is assessing procedural outcomes, including pacemaker rate, associated with in-procedure techniques and post-procedure TAVR care pathways when using the self-expanding, supra-annular Evolut Pro and Pro+ TAVR systems in patients with symptomatic severe aortic stenosis.
