The patients who were non-Fontan candidates due to respiratory conditions and miscellaneous reasons are all alive without further palliation at the time of the study. There are 17 patients (17\/31; 55%) in the non-candidacy group who had a heart transplant or were listed for transplant at the time of the study. Non-Fontan candidates had a higher incidence of moderate or severe atrioventricular valve regurgitation prior to superior cavopulmonary anastomosis.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1047951126111354_as4\">\n                    <jats:title>Discussion:<\/jats:title>\n                    <jats:p>Thirty-one patients (31\/427; 7%) were not Fontan candidates at our centre.
