Artefactual angulated lesion on angiography: A case report and review of literature

Sadat Ali Edroos et al. World J Cardiol. .

Abstract

We present a case of a patient who presented with chest pain, and on diagnostic coronary angiography appeared to have a grossly angulated yet significant coronary stenosis. This was proven to be an artefactual appearance on further assessment with intravascular ultrasound imaging. We describe the causes and associations of coronary tortuosity with other arteriopathy, and highlight challenges in the interpretation of tortuous vessels to accurately assess luminal narrowing and suitability for coronary intervention. We describe a case of artefactual coronary stenosis, and its thorough assessment with intravascular ultrasound. A literature review describes the pathogenesis of coronary tortuosity, and links with other cardiovascular disease. Readers will gain an understanding of the challenge in determining the severity of luminal stenosis based on coronary angiography alone in tortuous coronary anatomy, the use of intravascular ultrasound in this setting, and the allied vasculopathies of interest.

Keywords: Coronary tortuosity; Diagnostic coronary angiography; Intravascular ultrasound; Spontaneous coronary artery dissection.

Artefactual angulated lesion on angiography. The coronary angiogram, shown here in the AP caudal view, appears to demonstrate a significant lesion in the proximal left anterior descending coronary artery (arrow). There was no significant impediment to flow on pressure wire study, with no significant lesion seen on intravascular ultrasound.
