6.2 Establishing Chordae
Tendineae Length:
1. Once the remaining valve repair
procedures are completed,
and the length of each chordae
tendineae replacement suture is
then established. Suture lengths
are set to maintain the opposing
points of the two leaflets at the
same level in the ventricle.
2. Saline solution is injected into the
ventricular cavity to close the valve
(with aortic root venting for de-
airing). If residual regurgitant jets
are present or the closure line is
not symmetrical, adjust the length
of the Chord-X Sutures.
3. Knot the Chord-X ePTFE Suture
ends using at least seven (7) flat
square throws. Care should be
taken to avoid altering the length
of the suture while knotting.
Shortening of the artificial chordae
while knotting could result in over-
correction of the leaflet prolapse
and restrict the leaflet motion.
4. After the patient is
off cardiopulmonary
bypass, transesophogeal
echocardiography should be
used to confirm the results of
the hydrodynamic testing and
evaluate the valve repair.
