CTICasesAnomalous Left Coronary Artery from Right Cusp
Imaging findings
Coronary CT angiography in a 75-year-old male undergoing TAVR planning shows an anomalous left coronary artery arising from the right coronary cusp. The vessel has an interarterial course between the aorta and pulmonary artery, which was not compromised post TAVR.
Key takeaways
An anomalous left coronary artery arising from the right cusp with an interarterial course carries a high risk of sudden cardiac death in young patients. However, in older asymptomatic patients (e.g. 75 years old), it may be managed conservatively, and transcatheter valves can be safely deployed if the ostium is spared.
