Aortic coarctation MRI




 * Associate Editor-in-Chief:

Overview
Magnetic resonance imaging (MRI) can define the location and severity of a coarctation. MRI can also detect associated cardiac abnormalities and is used for serial follow-up after surgical repair or balloon angioplasty. MRI is recommended to look for aneurysm formation following repair of a coarctation. MR angiography has almost completely replaced invasive catheter based techniques for evaluating re coarctation. In adults with untreated coarctation blood often reaches the lower body through collaterals, eg. internal thoracic arteries via. the subclavian arteries. Those can be seen on MR or angiography.
