Anomalous origin of right coronary artery: Magnetic resonance angiography and viability study

Objective To detect origin and course and to evaluate viability in patients with anomalous RCA. Design 3D coronary MR angiography and viability study using gadolinium-enhanced magnetic resonance imaging (Gd-MRI) was performed. Setting A tertiary hospital center. Patients Four patients, selected from the catheter lab, were studied. Results Anomalous RCA from the left sinus of Valsalva was identified in all patients. Inferior myocardial infarction was documented in three patients. Conclusions Magnetic resonance imaging can non-invasively identify anomalous RCA and perform viability study in the same examination.
