The use of the GuideLiner™ catheter as a child-in-mother technique: an initial single-center experience.

Recently, a new interventional guide catheter, the GuideLiner™ catheter, was introduced into the market as a strategy for tackling the problem of stent delivery failure. We implemented this simplified child-in-mother technique in a series of 16 challenging coronary interventions. Balloon and stent delivery was successfully achieved in all cases and the device was both simple to deploy and remove. Apart from two cases of vessel dissection that were managed successfully with stent implantation, no other serious procedural complications were reported.
