Abstract
Purpose
It has been demonstrated that the coronary artery anomalies (CAAs) are generally asymptomatic. However, some cases can cause severe life threatening events. As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative to invasive coronary angiography for the evaluation of coronary anatomy, the prevalence of CAAs in CCTA may more closely reflect the true prevalence in the general population. So we aimed to review and determine the prevalence of CAAs and variants retrospectively in patients who underwent CCTA at our center.
Methods
Reports of 1802 patients who underwent CCTA at the radiology department of our university hospital were traced for CAAs. At least two independent investigators reviewed the images, which were selected for further assessment prior to final classification.
Results
One hundred and fifty two anomalies in 152 patients (8.44 %) were encountered. Origin of any coronary artery from the pulmonary trunk in 1 (0.06 %), origin of LMCA from right sinus in 1 (0.06 %), origin of right coronary artery (RCA) from left sinus in 5 (0.28 %), origin of left anterior descending artery (LAD) from right sinus in 2 (0.11 %), origin of circumflex branch (RCx) of LMCA from right sinus in 6 (0.33 %), origin of RCx from RCA in 4 (0.22 %), origin of any coronary artery from the ascending aorta in 2 (0.11 %), split RCA in 5 (0.28 %), RCx and left marginal artery from the first diagonal artery in 1 (0.06 %), myocardial bridging in 123 (6.83 %) and fistula in 2 (0.11 %) were detected as CAAs.
Conclusion
The prevalence of CAAs observed in this study was similar to the literature. CCTA can clearly visualize the anomalous origin, course and termination of the coronary artery.
期刊介绍：
The mission of Clinical Imaging is to publish, in a timely manner, the very best radiology research from the United States and around the world with special attention to the impact of medical imaging on patient care. The journal''s publications cover all imaging modalities, radiology issues related to patients, policy and practice improvements, and clinically-oriented imaging physics and informatics. The journal is a valuable resource for practicing radiologists, radiologists-in-training and other clinicians with an interest in imaging. Papers are carefully peer-reviewed and selected by our experienced subject editors who are leading experts spanning the range of imaging sub-specialties, which include:
-Body Imaging-
Breast Imaging-
Cardiothoracic Imaging-
Imaging Physics and Informatics-
Molecular Imaging and Nuclear Medicine-
Musculoskeletal and Emergency Imaging-
Neuroradiology-
Practice, Policy & Education-
Pediatric Imaging-
