the defibrillation thresholds of those patients who received
subcutaneous systems, and those who had a shock coil placed
directly on the pericardium. The epicardial systems were found
to have significantly lower defibrillation thresholds. It was
concluded that the epicardial coil technique would be preferable
in patients with greater body mass.
Conclusion
It is important to recognise that careful consideration must
be given to choose the appropriate technique in patients with
a Fontan operation and limited venous access. Techniques
for implantation of an ICD should be individualised in this
population. Long-term outcomes and possible complications
of these techniques are not well known because of limited data
in this patient group. Therefore regular follow up regarding the
longevity and safety of these non-traditional techniques and
devices is important.
