The fate of 191 infants with double-inlet ventricle was studied to
determine the influence of morphologic characteristics at presentation and
subsequent management on the potential for, and timing of, definitive
repair by the Fontan operation or ventricular septation. At presentation,
136 patients (71%) were potential candidates for a Fontan procedure.
Actuarial survival was better than for those deemed unsuitable for either
definitive option (n = 55; 68% versus 28% at 1 year; p less than 0.001),
but still, only 78 patients (57%) were known to be alive and suitable
candidates at 2 years of age. This was largely due to death after
presentation with low cardiac output (n = 19) and at palliative operation
(20 of 98 surgically treated patients). The adverse events of late sudden
death (n = 14) and the development of new features precluding a Fontan
operation (n = 18) mostly occurred before 4 years of age (n = 22). Patients
requiring no operation and those who underwent a systemic-pulmonary
arterial shunt fared better than those who underwent isolated banding of
the pulmonary trunk (9/13 and 25/42 alive and suitable versus 14/33; p less
than 0.05), and than those who required aortic arch repair together with
banding (1/12; p less than 0.01), because of the development of subaortic
stenosis in the latter group. In contrast, only 43 patients (23% of all 191
patients) had morphologic features that were additionally compatible with
future ventricular septation. Actuarial survival free of adverse events for
these 43 patients was similar to that of the 136 patients considered
suitable for a Fontan operation. Thus management in infancy must be aimed
at maintaining potential for a future Fontan operation, which itself should
not be delayed, for most patients, beyond 3 years of age, because of the
prevalence of adverse events with increasing age.
