Surgery in adult CHD patients can be performed with low operative mortality and good clinical outcome. EuroSCORE is not a good model for risk assessment in this group of patients.
In this study, selected patients with spiral anastomoses showed, two decades after ASO, better physiologically adapted blood flow dynamics, and attained a closer to normal anatomical position of their great arteries, as well as less valve dysfunction. Considering the limitations related to the small number of patients and the novel MRI imaging techniques, these data may provoke reconsidering the optimal surgical approaches to transposition of the great arteries repair.
The discriminatory power of the pediatric risk scores was suboptimal, but increased when adding age as a score component. The best performance was achieved by the combination of age and the Comprehensive Aristotle Score, for both 30-day and 1-year mortality.
Transposition of the great arteries (TGA) is caused by discordance between the great arteries and the ventricles. If left untreated, this anomaly has a disastrous perspective. More recent surgical approach for correction includes the Lecompte technique in which the pulmonary bifurcation is transposed anterior to the aorta, which may be less physiologic. Although the early results are excellent, there is potential for future problems involving the great arteries and semilunar valves1. These potential problems necessitate the development of other improved surgical techniques2. Here we report an MRI 4D flow study related to a case of simple TGA whose primary surgical correction – direct spiral arterial switch operation (DSASO) – was performed twenty years ago in an attempt to restore physiologic arrangement among the great arteries and semilunar valves.
In this TGA model, it was possible to perform tension- and torsion-free arterial anastomoses for ASO without artificial material, when the aortic root was positioned from 0° up to 35° to the right of the pulmonary root. Evaluation of coronary transfer is the next step.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
