Coarctation

It is important to measure the diameter of the ascending, transverse and descending aorta. In this suprasternal view, one may observe a posterior shelf (posterior aortic wall), as well as a narrowing at the level of the isthmus. It is important to assess this area with colour flow and CW-Doppler. Coarctation is a systemic-ductal dependent lesion.

One may appreciate the acceleration of flow at the level of the narrowing, as well as the right to left shunting via the ductus necessary for perfusion of descending aorta.
