In Search for Optimal Image Quality in Pediatric Cardiac CT Angiogram

“There can be no keener revelation of a society’s soul than the way in which it treats its children”. Years after his death, these Nelson Mandela’s prolific words still resonate universally with our moral and ethical foundations and, as researchers ourselves, we are very happy to know that Science walks on the right path of history.

There are a number of methodological and ethical challenges of performing research in children. However, there can be no progress in pediatric clinical care without research in this population, whose findings may also otherwise be relevant to adult medicine. Given that approximately 1% of born children will have some kind of significant heart disease, it is of crucial importance to maximize the safety and efficacy profile of diagnostic and therapeutic interventions. Computed tomography cardiac angiography (CTCA) is being increasingly used, but its diagnostic accuracy in children is highly dependent on optimal image quality while minimizing radiation exposure as much as possible.

Multislice coronary angiotomography in the assessment of coronary artery anomalous origin

Daniel Rocha Rabelo et al. Márcio Vinicius Lins Barros Maria do Carmo Pereira Nunes Cristiane Carneiro C. Oliveira Maria Helena Albernaz Siqueira

Background: Anomalous origin of coronary arteries is a relatively rare entity, which may show different clinical forms and develop an adverse outcome. Multislice coronary angiotomography has gained importance in daily clinical practice, representing an important patient assessment method with great potential in the anatomical evaluation of these arteries. Objective: This study aimed to describe angiotomographic findings and evolution of patients with anomalous origin of coronary arteries. Methods: From January 2008 to March 2011 404 patients were evaluated consecutively, who had been referred for coronary angiotomography for several reasons, with a mean follow-up of 21 months. Results: Nine patients (2.2%) had anomalous origin of coronary arteries, of which four had an anomalous origin of the Circumflex (Cx) artery in the Right Coronary Artery (RCA), two had anomalous origin of the RCA (one originating from the Cx and one in the left coronary sinus), a patient with single coronary trunk (anterior descending and Cx out of the left coronary sinus), one had anomalous left main coronary artery trajectory between the aorta and pulmonary artery and one patient with left coronary trunk originating from the right coronary sinus. Of the evaluated patients, one received an implantable cardiodefibrillator; one died due to sudden death during hospitalization; and the others showed no complications. Conclusion: The multislice coronary angiotomography represents minimally invasive assessment method that allows detecting the origin, course and termination of anomalous coronary arteries with excellent accuracy, allowing the correct diagnosis and aiding therapeutic planning.
