Summary: This week we review a recent survey study on the topic of aortopulmonary collaterals in single ventricle patients. How often are these occluded in the single ventricle patient and when this is performed, how do interventionalists decide? How should they be occluded? Are there guidelines regarding this? We speak with Professor Ziyad Hijazi of Sidra Cardiovascular Center in Doha, Qatar about this recent work and also briefly discuss the PICS Society for pediatric and adult interventional cardiologists with Dr. Hijazi and Dr. Damien Kenny. doi: 10.1007/s00246-020-02418-8
