Novel OCT flushing technique for complex scenarios: imaging during iatrogenic transient AV block induced by intracoronary adenosine.

ABSTRACT

We report the application of a novel optical coherence tomography (OCT) flushing technique where OCT run was performed during transient complete atrioventricular block induced by intracoronary bolus of adenosine. This technique may allow lower hydraulic force needed for contrast flush and reduce artifacts, with consequently improved OCT imaging in demanding clinical scenarios.
