Contact wire technique: a possible strategy for parallel wire techniques.

: One of the most commonly used techniques for percutaneous coronary intervention of chronic total occlusions (CTO) is the parallel wire technique. We illustrate in this case report a new variant of the parallel wire technique, the "contact wire technique", which is particularly useful for tortuous CTOs. We created contact between the second guidewire and the first guidewire, thus creating contact resistance. The contact resistance played an important role in making a pivot for the second guidewire, and enabled the second guidewire to face and advance to the true lumen.
