“…Although the literature includes case reports detailing IARCA instances, research series quantifying its prevalence remain scarce. Initially detected solely in post-mortem specimens and during heart surgeries, its observed frequency ranges from 0.1-1.8% [10,11,25]. IARCA's prevalence, as reported in autopsy or surgical cohorts is notably minimal [11].…”

“…The intra-atrial or intracavitary trajectory of the RCA is characterized by the RCA's passage through the right atrial cavity [10]. Radiographically, this manifests as an RCA segment that is consistently enveloped by intracavitary contrast throughout all phases of the cardiac cycle.…”

“…Radiologically, IARCA is characterized as an RCA segment entirely encompassed by intra-atrial contrast throughout the cardiac cycle, in contrast to MB, where the coronary artery segment appears entirely surrounded by myocardial muscle [9]. Recognition of IARCA prior to cardiac surgery or endocavitary procedures is imperative, given its potential for vascular injury leading to catastrophic consequences [10]. Initially identi ed in postmortem specimens and during cardiac surgeries, the prevalence of IARCA ranges from approximately 0.1-1.8% [8].…”

Purpose We aimed to determine the prevalence and radiological characteristics of myocardial bridging (MB) and intra-atrial course anomaly (IARCA), which are rare course variations of the right coronary artery (RCA), in the adult patient population. Methods Radiological images of cases over the age of 18 who underwent coronary CT angiography (CTA) examination in our clinic were scanned from the archives retrospectively, and cases with MB of the RCA and IARCA detection were included in the study. The number, age and gender distribution of the cases, whether there were any other accompanying vascular anomalies, whether there was atherosclerosis in the coronary arteries (calculation of Agatston total calcium score, calculation of atherosclerotic stenosis as a percentage, if any) were evaluated. Results The prevalence of MB in the RCA was 2.06%, and the prevalence of IARCA was 0.44%. In one case, both anomalies were detected together. The average MB segment length in RCA was 21.9mm, and the average IARCA segment length was 37.9mm. There was no atherosclerotic disease in the RCA segment where anomaly was detected. Conclusion Recognition of rare course anomalies of RCA before treatment procedures such as ablation and surgery is important to prevent complications that may have potentially fatal consequences.

Coronary artery anomalies are rare and may involve the coronary origin, course, or termination. Most are benign; however, some can lead to myocardial damage, sudden death, or potential hazards during interventional or surgical procedures. The advancement of imaging studies has led to an increase in their diagnosis. Coronary computed tomography angiography (CCTA) especially has characterized new anomalies that were previously anecdotal. This is the case of the intra‐atrial course of the right coronary artery. The present is a brief review about this rare congenital anomaly.
