• Resumen

  • Importance Transcatheter aortic valve replacement (TAVR) is an effective treatment option for high-risk patients with severe aortic stenosis. Different from surgery, transcatheter deployment of valves requires either a balloon-expandable or self-expandable system. A randomized comparison of these 2 systems has not been performed.

    Objective To determine whether the balloon-expandable device is associated with a better success rate than the self-expandable device.
