Similar Case of Anomalous Origin

I read the article regarding a single coronary artery by Namboodiri et al,1 published in the April 2007 issue of the Journal of Invasive Cardiology, with great interest. However, the authors missed referencing a few important publications related to their article. I had already reported a similar case of anomalous origin of the left anterior descending artery (LAD) from the right coronary sinus having a septal course, absence of a left circumflex artery (LCx), and an unusual dominant course of the right coronary artery (RCA) in the International Journal of Cardiology in June of 2005.2 Similarly, their comment about providing the only publication of direct continuation of the LCx from the terminal RCA also does not hold true, as it has been reported in the past by several clinicians.3– 5 Although the septal course of the LAD is clarified in the RAO and AP views by the authors, an additional LAO cranial view would have more clearly demonstrated the septal course of the LAD and also the unusual dominant course of the RCA. I do agree with the authors about the benign course of the anomaly, as my case also did not have any inducible myocardial ischemia despite having a similar anomaly.
