“…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.

The intracavitary coronary arteries (ICCA) course is a rare phenomenon, where the segments of the coronary artery go through the atria or ventricles of the heart. In the past, these changes were incidentally detected during invasive diagnostic procedures for other reasons, as well as during postmortem examinations. As the use of multidetector computed tomography angiography (CTA) becomes more widespread, it has emerged that the incidence of ICCA has been underestimated. We present images from two coronary computed tomography angiography cases, which document the existence of ICCA in patients with non-specific chest pain. In the first case, in a 66-year-old woman, in addition to confirming coronary artery disease without significant stenosis (CAD-RADS 2-category 2 in the coronary-artery-disease-reporting and data system), the course of the middle section of the right coronary artery (RCA) in the lumen of the right atrium was demonstrated. In the second case, in a 47-year-old man in whom the presence of atherosclerotic lesions in the coronary arteries was excluded (CAD-RADS 0), the course of the distal segment of the left anterior descending (LAD) was found in the lumen of the apical layers of the right ventricle. To sum up, it should be stated that coronary CTA is a non-invasive diagnostic method that allows for visualization of the ICCA. In coronary CTA performed for indications consistent with the guidelines of scientific societies, attention should also be paid to the possible intracavitary course of the coronary arteries. The identification of such a course of the coronary arteries may be useful when preparing the patient for potential future invasive procedures involving the cardiac cavities.
