Pediatric Cardio Flow and Supravalvar Aortic Stenosis (SVAS)

SVAS refers to a condition where there is a narrowing in the aorta right above the level of the aortic valve. This often congenital defect is found in children who are born with a genetic condition called the Williams Syndrome. SVAS is a challenging condition to assess, as routine ultrasound exams do not always provide accurate information about the blood flow and pressure around this lesion. The SVAS and pediatric cardio flow group is using novel ultrasound technologies called Vector Flow Imaging (VFI) and Blood Speckle Imagine (BSI) and  to better understand the implications of the lesions on the blood flow and the work load of the heart. These technologies are non-invasive imaging modalities, which has great potential in this vulnerable, pediatric cohort.
