Questions about “Intra-atrial right coronary artery on dual-source CT”

Abstract

I read with great interest the article by P Ganga et al. 1 , "Intra-atrial right coronary artery on dual-source CT: prevalence and characteristics, " published in Diagnostic and Interventional Radiology in the September-October 2021 issue. The authors described the prevalence and radiological features of the intra-atrial course of the right coronary artery (IA-RCA) in adults on coronary computed tomography angiography (CCTA). 1 The IA-RCA is a rare anomaly of the right coronary artery course; recognition of IA-RCA is important before carrying out ablative procedures for arrhythmias, catheterization of the right heart chambers, and pacemaker implantation. 1,2 I congratulate the authors for this interesting and instructive retrospective study. I suggest some points that need to be clarified in this article that could significantly contribute to the literature.
