Core Tip
Core Tip: Cardiac output, as measured by echocardiography, was larger in patients with small annuli who underwent transcatheter aortic valve implantation procedure with self-expanding valves compared to balloon-expandable in patients without atrial fibrillation. This observation should be considered during procedural planning.
