The “septal obliteration technique” using a single
oversized patch on the right ventricle
In patients with the true Swiss-cheese septum, adequate closure of the
multiple defects essentially requires ventricular septation. An
oversized composite patch of Dacron lined with preserved heterologous
pericardium with multiple points of intermediate fixation was used by
Cetin and other investigators with satisfactory short-term
results.4 Their outcome may be complicated by abnormal
ventricular function, and may require cardiac
transplantation.4,8,42,48,49,56-61 This technique has
also been described for multiple discrete muscular defects located in
the posterior, and apical part of the septum caudal to the moderator
band.
