ECG-less Coronary Computed Tomography Angiography in the Management of Patients Presenting With High-troponin Chest Pain

Chest pain represents a common reason for consultation to emergency room. This symptom can be explained by a broad spectrum of conditions, from benign musculoskeletal or esophageal pain to life-threatening disease such as aortic dissection, pulmonary embolism, and myocardial infarction. There are already different diagnostic tools to quickly identify most dangerous diseases, for example electrocardiogram, blood samples with specific markers of cardiac injury, chest X-ray and echography. In case a doubt of disease is raised after the first clinical evaluation, it is possible to proceed with more complex, expensive and invasive examinations, namely a computed tomography (CT) scan or an invasive coronary angiography (ICA). CT scan allows the diagnosis of various conditions such as pleural, pulmonary, pericardial and vascular disease such as pneumonia, pneumothorax, pleural and pericardial fluid, pulmonary embolism (PE), acute aortic dissection (AOD). In order to see the pulmonary, aortic and coronary arteries, a contrast injection is needed. Moreover, since the heart and the aortic root are continuously moving, specific technical measures to obtain good quality images are needed. Recently, a new CT scan system has been developed. It allows to obtain good quality images of the heart and aortic root using an estimated heart rhythm, without ECG-gating. This allows to perform a CT scan of the heart in a reduced amount of time, and without need for controlling heart rate. Moreover…
