Coarctation of the aorta is a congenital heart defect in pediatric patients, characterized by a narrowing of the aorta, typically near the ductus arteriosus. This constriction obstructs blood flow from the heart to the body, leading to increased pressure in the upper body and decreased pressure in the lower body. Early diagnosis via medical ultrasound is crucial for effective management and preventing complications.
Pediatric ultrasound plays a vital role in identifying coarctation, allowing for non-invasive assessment of the aortic arch and descending aorta. Sonographers look for direct visualization of the narrowing, increased blood flow velocity at the coarctation site, and post-stenotic dilation. This imaging technique is essential for monitoring growth, guiding interventions, and ensuring optimal outcomes for children with this condition.
