Anomalous Right Coronary Artery: Coronary CT Angiography Diagnosis, Treatment, Prognosis & AI
Anomalous Right Coronary Artery From the Left Coronary Cusp With Interarterial Course: A Coronary CT Angiography Guide to Diagnosis, Risk Stratification, Treatment, Prognosis, and AI By Dr. SB Lee Abstract A 30-year-old man presented with intermittent chest pain during exercise despite an otherwise unremarkable initial cardiac evaluation. Coronary CT angiography (CCTA) demonstrated an anomalous origin of the right coronary artery (RCA) from the left coronary cusp rather than the normal right coronary sinus. The anomalous RCA subsequently coursed between the great vessels, producing an interarterial course . Importantly, the coronary ostium demonstrated a slit-like morphology and an acute take-off angle , two anatomic features that may increase concern for dynamic coronary flow limitation. This case illustrates why coronary CT angiography should not be interpreted simply as a search for coronary stenosis or calcified plaque. In patients with suspected anomalous aortic origin of a...
