Figure 5: In vitro experiment with IS-1 pacing lead in a porcine heart.
Attempts at septal penetration by torquing the lead body without
re-extending the helix. Note retraction of the helix with only 1 turn of
the helix extending beyond the mapping collar of the lead. There is
resultant tearing and retention of a small amount of myocardial tissue
at the helix. Inadvertent lead dislodgement occurs, with a shallow lead
tract demonstrated in the myocardium.
