title: Diagnosis and management of anomalous origin of the right coronary artery from the left coronary sinus.
abstract: The anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva coursing between the aorta and the pulmonary artery or right ventricular outflow tract, is considered a potentially fatal abnormality which may require surgery. However, diagnosing the correct course with coronary arteriography may be difficult. Fast gradient echo magnetic resonance (MR) imaging can be helpful to identify and confirm the course of aberrant coronary arteries and their relationship to the surrounding tissue. In this study, diagnostic procedures and management are described of four patients in whom the RCA originated from the left sinus of Valsalva. Although reported as investigational by the Task Force document on MR imaging by the European Society of Cardiology we are of the opinion that MR coronary angiography may have an important future role in the assessment of anomalous coronary arteries.
