BACKGROUND: Selection of transcatheter valve size using preprocedural computed tomography (CT) is standardized and well established. However, valve sizing for surgical aortic valve replacement (SAVR) is currently performed intraoperatively using sizers, which may result in variation between operators and risk for prosthesis-patient mismatch. This study evaluated the usefulness of CT annulus measurement for SAVR valve sizing. METHODS: We studied patients who underwent SAVR using Inspiris or Magna Ease and received preoperative ECG-gated CT imaging...
