Distal balloon deflation technique: a new method to facilitate entry of balloon catheter, stent, and guiding catheter to distal lesion.

We occasionally encountered difficult cases of balloon and stent delivery to the distal lesion because of narrow stent strut, severe calcification, or tortuosity of the proximal section. We describe a new technique to deliver balloon, stent, and guiding catheter to the distal lesion using a distal balloon deflation. This technique offers a potential alternative for cases in which the delivery of balloon and stent is difficult.
