<p>AV canal is a complex heart condition and several different
techniques of repair have been used. We present different techniques that we
adapt to individual patient anatomy.</p>
<p>The first infant we presented had complete AV canal with a
large VSD with minimal chordal attachments to the ventricular septum. We
utilised a two patch technique with two autologous pericardial patches in this
patient because we believe that had the lowest chance of distortion of the AV
valve leaflets. </p>
<p>The second infant had complete AV canal with multiple dense
chordal attachments of the AV valve leaflets to the ventricular septum and so
we utilised the "Australian" technique for repair with one autologous
pericardial patch.</p>
<p>The third patient had a partial AV canal but presented at an
older age and so had dilation of the mitral annulus with moderate mitral
regurgitation. Simple cleft closure in this patient was not adequate to repair
the mitral regurgitation. An additional commisuroplasty had to be performed on
the annulus near the junction of the inferior bridging leaflet and the mural
leaflet.</p>
All patients had a successful repair with
uncomplicated post operative course. Different surgical approaches can be used
with AV canal with differing intracardiac anatomy to obtain best surgical
outcomes.
