ABSTRACT
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.

We present a 49-year-old female case of anomalous origin of the left main coronary artery from the pulmonary trunk. Multidetector computed tomography was performed, and 3-dimensional reconstruction of computed tomographic images found that the left main coronary artery originated from left sinus of the pulmonary trunk and the right coronary artery from the right coronary cusp of the aorta. We speculate that this patient's long life may be due to the dominant right coronary artery and rich collateral from the right coronary artery to the left coronary artery.
