Background:
Because optical coherence tomography (OCT) requires balloon-occlusion to overcome image attenuation by blood, the present study investigated the safety and usefulness of a new non-occlusive technique.
Methods And Results:
The 40 angina patients were assigned to the continuous-flushing method or the balloon-occlusion method group. The continuous-flushing method was superior for observing proximal lesions compared with the balloon-occlusion method (94% vs 55%, p=0.01). There were no differences between groups in the visible length and image quality. There were no major complications during OCT.
Conclusions:
The continuous-flushing method is safe and useful for OCT.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
