Abstract
Pulmonary vasodilators increased the systemic-to-pulmonary collateral flow in two single-ventricle cases, causing haemodynamic decline. Discontinuation reversed the collateral flow and improved heart failure, highlighting the need for careful monitoring. Serial cardiac MRI, as a non-invasive tool, may be essential to detect changes in collateral flow and guide vasodilator use for optimal management in this population.
期刊介绍：
Cardiology in the Young is devoted to cardiovascular issues affecting the young, and the older patient suffering the sequels of congenital heart disease, or other cardiac diseases acquired in childhood. The journal serves the interests of all professionals concerned with these topics. By design, the journal is international and multidisciplinary in its approach, and members of the editorial board take an active role in the its mission, helping to make it the essential journal in paediatric cardiology. All aspects of paediatric cardiology are covered within the journal. The content includes original articles, brief reports, editorials, reviews, and papers devoted to continuing professional development.
