Recommended Techniques; Suture Placement - On-X CHORD-X ePTFE SUTURE Mode D'emploi

English
Reuse may cause device failure or
procedural complications including
device damage, compromised
device biocompatibility, and device
contamination. Reuse may result in
infection, serious injury, or patient
death.

6. RECOMMENDED TECHNIQUES

6.1 Suture Placement:

1. After determining the number of
chordae tendineae that will be
replaced, a Chord-X ePTFE Suture is
placed through the papillary muscle,
with a pledget placed on each side
of the muscle (Figure 1). The suture
is then tied. This knot should be tied
loosely to avoid ischemia to the tip
of the papillary muscle.
2. After all of the sutures have been
anchored to the papillary muscle,
the two sides of each suture are
run through the free margin of
the leaflet (approximately 2mm
apart). It is useful to increase the
friction of the suture in the leaflet
to minimize suture slippage during
the suture length adjustment
steps. Therefore, pass each side
of the suture through the leaflet
twice (Figure 2). An autogenous or
thin ePTFE pledget (not supplied)
may be placed on the atrial side
of the leaflet for reinforcement
(Figure 3).
