To ensure similar baseline characteristics, we performed a propensity score matching based on left ventricular ejection fraction, age, body surface area, and aortic annulus diameter measured by intraoperative transesophageal echocardiography. Thereafter, 48 patients remained in each group. Mean age at operation was 67\u2009\u00b1\u20096 years and mean EuroSCORE-II was 1.7\u2009\u00b1\u20091.1. Both values did not differ significantly between the two groups.<\/jats:p><jats:p>\n          Results\u2003At 1 year the mean pressure gradient (MPG) was 15.4\u2009\u00b1\u20094.3\u2009mm Hg in the PME group and 14.7\u2009\u00b1\u20095.1\u2009mm Hg in the Avalus group (p\u2009=\u20090.32). The effective orifice area (EOA) was 1.65\u2009\u00b1\u20090.45\u2009cm2 in the PME group and 1.62\u2009\u00b1\u20090.45\u2009cm2 in the Avalus group (p\u2009=\u20090.79). At 5 years the MPG was 16.6\u2009\u00b1\u20095.1\u2009mm Hg in the PME group and 14.7\u2009\u00b1\u20097.1\u2009mm Hg in the Avalus group (p\u2009=\u20090.20). The EOA was 1.60\u2009\u00b1\u20090.49\u2009cm2 in the PME group and 1.51\u2009\u00b1\u20090.40\u2009cm2 in the Avalus group (p\u2009=\u20090.38). Five-year survival was 88% in the PME group and 91% in the Avalus group (p\u2009=\u20090.5). In the PME group, there were no reoperations on the aortic valve, whereas in the Avalus group three patients required a reoperation due to endocarditis.<\/jats:p><jats:p>\n
