Insights
Coronary computed tomography angiography (CCTA) accurately evaluates rare coronary artery anomalies. This non-invasive imaging technique is crucial for diagnosing and differentiating between benign and malignant variants, guiding appropriate patient management.
Area of Science:
- Cardiology
- Medical Imaging
- Congenital Heart Disease
Background:
- Coronary anomalies are rare but can lead to sudden cardiac death in young individuals.
- Coronary computed tomography angiography (CCTA) provides detailed 3D visualization of coronary artery anatomy.
- CCTA aids in differentiating benign from malignant coronary anomalies, crucial for treatment decisions.
Purpose of the Study:
- To establish coronary computed tomography angiography (CCTA) as the preferred non-invasive method for evaluating coronary anomalies.
- To highlight the high diagnostic accuracy of CCTA in identifying coronary artery variations.
Main Methods:
- A retrospective analysis of 368 coronary computed tomography angiographies (CCTA) performed between 2008 and 2014.
- Identification and characterization of coronary anomalies in the study cohort.
Main Results:
- Six patients (1.6%) were diagnosed with a coronary anomaly.
- The anomalies included variations in the right and left coronary arteries, and absent left main coronary artery.
- Five of the six identified coronary anomalies were classified as malignant, indicating a significant risk.
Conclusions:
- Coronary computed tomography angiography (CCTA) is a reliable and effective diagnostic tool for assessing patients with suspected coronary anomalies.
- The high accuracy of CCTA supports its role as a primary imaging modality for these conditions.
Background:
Coronary anomalies are rare heart diseases that can cause sudden cardiac death, especially in young individuals. Coronary computed tomography angiography delivers a three-dimensional view of excellent quality with information of the origin, course and anatomic relationships of the anomalous vessel, allowing differentiation between benign and malignant variants, entities that require different management and treatment.
Aim:
To show that coronary computed tomography angiography is the non-invasive technique of choice for the evaluation of a coronary anomaly due to its high diagnostic accuracy.
Material And Methods:
Between 2008 and 2014, 368 coronary computed tomography angiographies were carried out. Six (1.6%) patients had a coronary anomaly.
Results:
The age of these six patients ranged from 38 to 82 years (five were women). The coronary computed tomography angiography was requested due to cardiac symptoms (angina and dyspnea) in two patients, after a selective coronary arteriography to obtain additional information of the coronary anomaly in three patients, and after a cardiorespiratory arrest in one patient. Three patients had an anomaly of the right coronary artery, two patients had an anomaly of the left coronary artery and one patient had absent left main coronary artery. In five patients the coronary anomaly was malignant.
Conclusions:
Coronary computed tomography angiography is a robust diagnostic method to evaluate patients with suspected coronary anomalies.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
