Coronary Stenoses Caused by Extensive Calcification – Hemodynamic Relevance?

Prof. Steven Dymarkowski, MD
Department Radiology, University Hospital Leuven, Belgium

A 70-year-old female patient, suffering from chest pain with both typical and atypical elements, presented herself to the hospital. The patient had an intermediate coronary risk profile and a history of coronary stenosis (70% in ramus intermedius) revealed in a conventional coronary angiography from 2010. A stress-ECG test was inconclusive. A comprehensive cardiac CT study, including Coronary CT angiography (CTA) and Stress Myocardial Dynamic Perfusion, was ordered to simultaneously evaluate both the coronary arteries and the myocardium.
