Figure legends
Figure 1. The loop technique proposed by von Oppell and
Mohr22 (see text)
Figure 2. A different use of a caliper was proposed by Doi et
al.28 (see text)
Figure 3. Loops are tied at a predetermined length temporarily fixing
them at a specific length using a slit tube, as proposed by Chang et
al33
Figure 4. Chan et al36 proposed the use of a covered
clip holding the chords at the correct length, allowing them to be tied
without movement
Figure 5. Calafiore21 proposed to pull the anterior
leaflet (AL) with nerve hooks up to its maximum length and then to tie
the artificial chord adding 5 mm to the border of the AL
Figure 6. Maselli et al40 proposed a tuneable loop
technique (see text)
Figure 7. Shudo et al20 proposed to tie multiple knots
to a normal leaflet scallop so to calculate the number of knots to use
in the prolapsing scallop, tying the suture only after filling test, in
order to prevent knot-slipping.
