“…Indeed, it is generally superior in newer compared with older generations of prostheses, in mechanical compared with stented bioprosthetic valves, 16 in stentless compared with stented bioprosthetic valves, 17,18 and in supraannular compared with intra-annular stented bioprostheses. 19,20 A recent meta-analysis 18 shows that, compared with stented bioprostheses, stentless valves provide larger EOAs, reduced transprosthetic gradients, and greater left ventricular (LV) mass regression, but at the expense of prolonged cardiopulmonary bypass time.…”

“…Pressure gradients of the Magna, the Mosaic, and the Soprano are in accord with findings of other groups. 1,[3][4][5][6]8,13,14,20,22,[25][26][27][28][29][30][31] There are preliminary in vivo hemodynamic data available regarding the Mosaic Ultra 10 and only 1 in vivo evaluation of the Epic, which was published previously by our group. 4 The in vitro data concerning hemodynamic gradients of the Epic and the Ultra correspond well with our results.…”

“…1,3,6,8,[25][26][27] The annulus diameter is used in 5 of the 7 in vivo studies as a comparing parameter (online supplemental Table 4). The hemodynamic gradients are low for all annulus sizes; the lowest gradients were described by Botzenhardt in patients with an annulus diameter of 22 to 23 mm (7.3 mm Hg) 27 and the highest in patients with an annulus diameter of 18 to 22 mm (13.2 mm Hg). 8 …”

“…The projected EOAIs in the three PPM cases were not B0.85 cm 2 /m 2 preoperatively (projected EOAIs were 0.93 cm 2 /m 2 in case 1, 0.99-1.05 cm 2 /m 2 in case 2, and 1.19 cm 2 /m 2 in case 3). However, when the projected EOAI was calculated as per the results of Botzenhardt et al [15] and Dalmau et al [16], it would be B0.85 cm 2 /m 2 or around 0.85 cm 2 /m 2 (Figs. 4, 5).…”

“…Dalmau et al [6] reported substantially better hemodynamic outcomes after 11 months when using a Perimount Magna bioprosthesis than when using a standard Perimount. Several studies that used the 19-mm Perimount Magna bioprosthesis reported the EOA to be 1.58 ± 0.29 cm 2 (n = 5) [6], 1.65 ± 0.84 cm 2 (n = 4) [15], and 1.35 ± 0.31 cm 2 (n = 2) [16]. In our study, good hemodynamic performance was observed at follow-up, and the measured EOA for the 19-mm prosthesis was larger population than that have been reported (Table 5).…”
