A first group of 190 patients had annular sizes for which only moderate oversizing degree was feasible (5\u201320% by area or 2.5\u20139.5% by perimeter). A second group included 178 patients that had annulus size for which only large oversizing degree was feasible (20.1\u201335% by area or 9.6\u201316.2% by perimeter).
