Percutaneous intervention of chronic total occlusion of anomalous right coronary artery originating from left sinus - Use of mother and child technique using guideliner.

Anomalous origin of right coronary artery (RCA) from left sinus is a rare clinical entity. Percutaneous coronary intervention of such an anomalous RCA, which is chronically occluded, is difficult and is rarely described. We describe such an intervention in a patient, who had a chronic total occlusion of anomalous RCA and discuss the technical issues associated with such interventions.
