Application of prospective ECG-triggered dual-source CT coronary angiography for infants and children with coronary artery aneurysms due to Kawasaki disease

Abstract: Objectives: The aim of this study was to prospectively evaluate the initial application and value of prospective electrocardiogram (ECG)-triggered dual-source CT coronary angiography (DSCTCA) in the diagnosis of infants and children with coronary artery aneurysms due to Kawasaki disease. Methods: 19 children [12 males; mean age 13.47 months, range 3 months to 5 years; mean heart rate 112 beats per minute (bpm), range 83-141 bpm] underwent prospective ECG-triggered DSCTCA with free breathing.

“…4 Radiation hazard with CTCA (and consequent risk of radiation-associated malignancy) remains a concern still even though it is much less than in the older generation scanners. Dose-saving strategies in CTCA include child-size bowtie filter, 5 body size-adapted protocol including low tube voltage techniques, 6 highpitch scanning (more overlap of scanned data), 7 electrocardiogram (ECG)-controlled and attenuation-based tube current modulations (CT exposure modifications with phase of ECG), 8 and prospective ECG-triggered sequential scanning (in which CT data are acquired only during a particular cardiac phase through synchronization of the X-ray tube and the ECG signal 9 ) and iterative image reconstruction methods. 10 Using the dose-saving strategies discussed above, radiation doses of CTCA have been brought to levels below 1 mSv.…”

“…On the other hand, there is growing interest in the application of dual-source CT technology in the assessment of coronary artery aneurysms complicating Kawasaki disease [25]. Duan et al [26] concluded that prospective ECG-triggered dual-source CT coronary angiography provides excellent image quality, bears low radiation exposure and is useful for diagnosing infants and children with coronary artery aneurysms due to Kawasaki disease. It can be an alternative diagnostic modality to transesophageal echocardiography [25,26].…”
