TLDR
The histological study showed that the ductus was easily distinguished from the walls of the aorta or pulmonary artery, and the anatomical study of the hearts with obstructive aortic lesions emphasised the necessity of distinguishing 'coarctation' from 'tubular hypoplasia'.Abstract:
A histological study has been made in an attempt to study further the relation between the ductus arteriosus, coarctation, and tubular hypoplasia of the aortic arch. Thirty-five aortic arch systems were studied using serial sectioning techniques. Twelve were from patients with coarctation and/or tubular hypoplasia. The other 23 hearts were from patients without aortic obstructive lesions, 7 from anatomically normal hearts, and the others from malformed hearts with anomalies elsewhere from the aortic arch. The anatomical study of the hearts with obstructive aortic lesions emphasised the necessity of distinguishing 'coarctation' from 'tubular hypoplasia', since the curtain lesion of coarctation was found to coexist with tubular hypoplasia in some cases. The histological study showed that the ductus was easily distinguished from the walls of the aorta or pulmonary artery. In all these cases with coarctation or tubular hypoplasia a sling of ductal tissue was located around the aortic isthmal orifice. In 6 hearts a diaphragm of ductal tissue was seen to form the coarctation lesion.read more

Congenital Variants and Anomalies of the Aortic Arch
TL;DR: Cross-sectional imaging techniques used in the evaluation of the aortic arch are reviewed, the embryology and anatomy of theAortic Arch system is described, and other malformations of the analsis are discussed, including interrupted aorti arch, hypoplastic aorta, and aorting coarctation.

TL;DR: Low recoarctation rate, effective relief of the obstruction created by aortic arch hypoplasia and to complete resection of ductal tissue, freedom from major morbidity, and feasibility via both lateral and anterior approaches are the main advantages of the extended end-to-end anastomosis.

TL;DR: In this article, the authors reviewed the prenatal echocardiograms and postnatal outcome of 20 infants (gestational age at initial study 18 to 36 weeks) with coarctation of the aorta established postnatally.

Late complications in patients after repair of aortic coarctation: implications for management.
TL;DR: Cardiovascular complications are frequent and require indefinite follow-up, with particular reference to late hypertension, and concern falls chiefly in seven categories: recoarctation, aortic aneurysm formation or aortsic dissection, coexisting bicuspid aortIC valve, endocarditis, premature coronary atherosclerosis, cerebrovascular accidents and systemic hypertension.

Hemodynamic considerations in the development of narrowing of the aorta
TL;DR: It was postulated that constriction of the ductus arteriosus after birth would produce obstruction, and this was confirmed experimentally in fetal lambs with surgically simulated juxtaductal coarctation.

Coarctation of the Aorta
TL;DR: A congenital constriction of the aorta in the distal part of theAortic arch, usually in the isthmus region and close to the site of insertion of the ductus arteriosus, is a congenital condition.

TL;DR: There were one or more associated anomalies in 87 cases, that is 91% of the patients under 6 months of age and in 74% of those in the older group, exclusive of cases of bicuspid aortic valve.
