Their outcomes were reviewed to identify predictors of adverse events with a particular focus on the impact of morphological characteristics. All available echocardiographic parameters were collected, and the hypoplasia of the left ventricle was subjectively considered to be mild, moderate or severe.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The mean follow-up after the Fontan procedure was 6.4\u2009\u00b1\u20094.7\u2009years. The median age at Fontan procedure was 4.41\u2009years, 95% (176\/185) of patients underwent an extracardiac conduit Fontan procedure and 71% (132\/185) of those were fenestrated. At 15\u2009years after Fontan, freedom from death and cardiac transplantation was 90% [95% confidence interval (CI) 85\u201397], freedom from Fontan failure was 78% (95% CI 70\u201387) and freedom from adverse events was 32% (95% CI 22\u201346).
