NEW ORLEANS — Frail, elderly patients with aortic stenosis who underwent a transcatheter aortic valve replacement (TAVR) procedure had about the same survival at one year as similar patients who had conventional open-heart surgery. But the TAVR patients were also more likely to have a stroke following the procedure, according to highly-anticipated preliminary data presented Sunday at American College of Cardiology's (ACC; Washington) 60th annual scientific session.
