However, its use in Japanese patients is poorly understood. We retrospectively compared the feasibility, safety, and valve haemodynamics between the Avalus\u2122 and Magna\u2122 valves in patients who underwent surgical aortic valve replacement (SAVR).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>This study included 87 patients receiving an Avalus\u2122 valve and 387 receiving a Magna\u2122 valve. We evaluated adverse events, outcomes, and valve haemodynamics within 1\u00a0year postoperatively.

No pacemaker implantation for complete atrioventricular block was required in the Avalus\u2122 group. There was no significant difference in in-hospital or clinical outcomes between the two groups until 1\u00a0year postoperatively. Left ventricular mass index reduction appeared to predominate in the Avalus\u2122 over Magna\u2122 group. There was no significant difference in the mean pressure gradient or effective orifice area of each valve size at 1\u00a0week or 1\u00a0year between the two groups, apart from the mean pressure gradient of the 23-mm valve at 1\u00a0week.
