Comment
Redo-procedures in cardiac surgery can be difficult and there are not too many
tricks to make things easier. The authors report the use of a new surgical
technique based on modern cannula design, i.e. use of a single
self-expanding
cannula in combination with gravity drainage of both caval
veins for an open
right heart operation. The trick here is due to several
specific features of
the anatomy and the cannula used:
A) in a
supine patient, the tricuspid orifice is a few centimeters above the
inferior vena cava, i.e. above the blood level in the cases shown. This can
be
seen easily seen in routine CT slices of the heart with some contrast in
the
caval veins
B) in a supine patient, the drainage point (here the
femoral vein) is usually
below the tricuspid orifice. Again, this can be
checked prior to the procedure
with a CT-scan
C) the cannula used
has no wall, but acts as a spacer in the venous
vasculature. Hence, the
blood can enter the cannula lumen directly at all
intravenous levels. This
is very much in contrast to traditional percutaneous
cannulas, where the
blood has to travel to the right atrium, before it enters the cannula
orifices at the tip. This also also explains the immediate air-lock with
traditional
cannulas within an open right atrium
D) due to the
self-expanding mechanism, the mean cross-sectional area of the
cannula to
used can be selected well above that of access vessel selected and
therefore gravity is enough for adequate venous drainage in this
setting.
