An interarterial course of anomalous left main coronary artery originating from the right aortic coronary sinus of valsalva is a rare condition among anomalous aortic origin of the coronary artery. Various surgical options are available. We performed an alternative procedure, that is, mobilisation of the pulmonic root, pulmonary bifurcation, and plication of the pulmonic root adjacent to the left main coronary artery, in a 12-year-old boy. Favourable results were achieved after 43 months of follow-up.
