Abstract

The clinical relevance and anatomic characteristics of intracavitary coronary arteries coursing within the right ventricle (RV) are largely unknown. The aim of our study was to assess the clinical and computed tomographic characteristics of patients diagnosed with intracavitary coronary arteries coursing within RV (intra-RV coronaries). Electronic records from a single high-volume cardiac center were retrospectively screened for the presence of intra-RV coronaries among consecutive patients who underwent coronary computed tomography angiography (coronary CTA) from 2008 to 2019. Overall, 31,748 coronary CTA reports were evaluated, and 17 subjects with intra-RV coronaries were identified. None of these patients was referred for subsequent invasive coronary angiography. One patient underwent coronary artery bypass grafting, 1 patient had a history of percutaneous coronary intervention, and 1 patient had a concomitant coronary anomaly: left circumflex coronary artery originating from the right coronary artery. All of the involved coronaries (n = 17) were the left anterior descending coronary arteries (LADs). Typical segmental coronary course within RV was along the border between free RV wall and interventricular septum (beneath in...Continue Reading
