Objectives:
Side branch protection during rotational atherectomy is an issue when treating bifurcations, particularly left main one. The authors investigated the effectiveness of side-branch protection with a microcatheter.
Methods:
On a simulator we evaluated the behavior of different microcatheters left in place into the side branch during rotational atherectomy.
Results:
All microcatheters were variously damaged.
Conclusions:
The authors discourage the practice of side-branch protection with a microcatheter, due to distal embolization of non-biological materials.
