“…Echocardiography, however, has limitations in adult patients and MRI imaging using gradient echo cine, dark black blood, and 3D gadolinium-enhanced angiography will enable optimal imaging for case selection prior to percutaneous intervention. 5 During catheterization, demonstration of a blind ending descending thoracic aorta is not sufficient to make the diagnosis of interruption, as many severe coarctations provide a similar appearance. It is essential for an ascending aortogram to confirm the diagnosis of atresia or interruption.…”

Two adult patients with isolated, aortic interruption were successfully treated by percutaneous insertion of graft stents. Prior to the intervention, both patients were hypertensive and on medication. In both cases, an ascending aortogram demonstrated a blind ending of the thoracic aorta distal to the left subclavian artery with a large gradient across the interruption and with multiple collaterals. A graft stent was successfully deployed across the interrupted segment in both cases. We believe that this is one of the first reported cases of percutaneous stenting of aortic interruption and represents a promising new therapeutic option for these adult patients.

“…Compared with echocardiography, cMRI demonstrates superior visualization of the aortic arch with precise characterization of the location and extent of coarctation, and assessment of the presence and extent of collateral vessels. n the unrepaired patient, the measured minimum aortic cross-sectional area and heart rate-corrected deceleration time in the descending aorta can be used to predict a significant gradient by cardiac catheterization [59] and future need for interventions. cMRI provides exceptional visualization of the aortic arch and detection of post repair complications including arch "kinking" and pseudoaneurysms.…”

The manuscript will discuss the epidemiology and etiology of the adult with coarctation of the aorta (CoA) as well as describe the embryology, anatomy, pathophysiology, and clinical presentation in order to recognize and appropriately diagnose an adult patient with CoA. This chapter will also review diagnostic testing, management, therapeutic interventions including percutaneous and surgical procedures, and long-term complications that can arise in an adult with repaired CoA. It contains images with examples from echocardiography, cardiac computed tomography (CT), magnetic resonance imaging (MRI), and angiograms as part of the description.

“…The percent increase in volume provides a quantitative measurement of (re‐)coarctation severity (34). In addition, another study validated CMR against catheterization to assess re‐coarctation severity in 31 patients (35). 3D‐MRA was used to assess the diameter of the narrowest coarctation segment.…”

“…Additionally, with phase‐encoded flow MRI at the thoracic descending aorta, the deceleration velocity of flow was obtained as a quantitative measure of flow obstruction. Using this combined approach, CMR could differentiate between a transcatheter pressure gradient >20 mmHg or below 20 mmHg with high sensitivity (95%) and specificity (82%) (35).…”

The survival of patients with congenital heart disease (CHD) has greatly improved over the past decades. Nevertheless, lifelong follow‐up is required in postoperative CHD patients, and noninvasive imaging plays an important role during follow‐up. Cardiac MR (CMR) imaging enables comprehensive imaging of cardiac function and anatomy, and helps to detect patients who need re‐intervention and to predict clinical outcome. Postoperative CHD patients who are frequently referred for CMR evaluation include those with coarctation of the aorta, tetralogy of Fallot, transposition of the great arteries, and single ventricle patients after the Fontan procedure. This article reviews the current clinical role of CMR in these various subgroups of postoperative CHD patients. Furthermore, an overview of novel CMR applications and their clinical value in CHD patients is provided. J. Magn. Reson. Imaging 2012;36:511–528. © 2012 Wiley Periodicals, Inc.
