Normal aortic arch growth and comparison with isolated coarctation of the aorta

Comparison of Surgical, Stent, and Balloon Angioplasty Treatment of Native Coarctation of the Aorta

“…Review of the literature revealed no evidence to support the determination of successful treatment of coarctation of the aorta on the basis of angiographic outcomes alone. In normal patients, the aortic isthmus is 80% to 90% of transverse aortic diameter and similar to descending aortic diameter at level of the diaphragm by angiographic imaging (18). The CCISC experience, consistent with others (19,20), confirmed that the majority of patients requiring reintervention for recoarctation had a Coarct:Dao ratio of Ͻ0.60.…”

Validation of two echocardiographic indexes to improve the diagnosis of complex coarctations

“…Associated anomalies of the aortic arch with isolated coarctation, in particular displacement of the left subclavian artery and narrowing of the distal transverse arch, have been widely described [4][5][6][7][8][9][10]. Their presence, independent of haemodynamic repercussions of the coarctation, has not been used for the diagnosis until recently.…”

Computational fluid dynamic simulations for determination of ventricular workload in aortic arch obstructions

“…The computed tomography angiography image data were quantitatively analyzed to determine the aortic diameter at the sinotubular junction, proximal to the right innominate, distal to the left common carotid artery, distal to the left subclavian artery, and at the diaphragm. These measurements were then compared against the data collected by Aluquin and colleagues 4 at the same aortic locations for normal subjects to quantify the degree of narrowing. The computational models for the 4 patients and their respective BSA-matched controls are shown in Figure 1.…”

“…In the present study, we sought to define aortic hypoplasia according to the location and degree in reference to the normal anatomy. 4 Next, using computational simulations, we investigated the hemodynamic significance of the different types and degrees of aortic hypoplasia.…”
