Core Tip

Core tip: Coronary arteries are inherently tortuous, and are assessed at angiography, compressing a 3D structure into a 2D picture. An overly tortuous artery may resemble true luminal stenosis, rather than mere angulation, and may be interpreted as a significant coronary stenosis. We present a remarkably angulated coronary artery, which appeared to bear a significant stenosis. On further assessment with pressure wire study and intravascular ultrasound we found there to be no significant lesion. We demonstrate an artefactual false-positive finding, and describe our clinical approach to avoid mistaking such a lesion for one that requires intervention, with a review of the literature.
