A 10-year single-centre report on Fontan attrition and non-Fontan candidacy

Thirty-one patients (31/427; 7%) were not Fontan candidates at our centre. Our results demonstrate that the reasons for non-Fontan candidacy after completion of stage 2 are broadly due to echocardiographic findings and respiratory concerns. Predicting non-Fontan candidacy prior to superior cavopulmonary anastomosis remains difficult.
