A total of 60 (57%) had undergone previous surgical interventions: 34 with 1, 15 with 2 and 11 with \u22653. There was one early death in a 12-year-old girl, who underwent her fourth aortic valve operation, due to intracerebral haemorrhage on extracorporeal membrane oxygenation after coronary reimplantation problems following 3-sinus reconstruction 1 year earlier. One 2-year-old patient died due to sepsis 2\u2009months postoperatively with no evidence for endocarditis. In addition, a single pacemaker implantation was necessary and a 2.5-year-old girl underwent successful HTx due to chronic myocardial failure despite an intact DAH. After a mean follow-up of 3.30\u2009\u00b1\u20092.45 years, primary efficacy end points mean peak gradient (18.1\u2009\u00b1\u200920.9\u2009mmHg) and regurgitation (mean 0.61\u2009\u00b1\u20090.63, grade 0\u20133) were very good. Freedom from death\/explantation\/endocarditis\/bleeding\/stroke at 5 years was 97.8\u2009\u00b1\u20091.6\/85.0\u2009\u00b1\u20097.4\/100\/100\/100% respectively. Calculated expected adverse events were lower for DAH compared to cryopreserved homograft patients (mean age 8.9 years), lower than in Ross patients (9.4 years) and in the same range as mechanical AVR (12.8 years).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Even though the overall number of
