MRI

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. 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.

Therapy

Therapy is conservative if the patient is asymptomatic. If symptoms or hypertension are present, treatment for coarctation may be surgical or catheter based. The treatment choice depends on the patients age, the location of the coarctation and other associated anomalies. Recoartctaion after previous surgery is treated percutaneously with either balloon dilation and/or stenting.
