Abstract:
In rat thoracic aorta, contractile responses to arginine vasopressin (AVP) are twofold higher in females than in males. To determine the role of the endothelium in this phenomenon, the effects of endothelium removal and inhibition of nitric oxide (NO) synthase and cyclooxygenase were examined in thoracic aortas prepared from male and female Sprague-Dawley rats and mounted for isometric tension recording. Maximal contractile response to AVP was substantially higher in female (4,232 +/- 316 mg/mg ring dry wt) than in male aortas (1,365 +/- 239; P < 0.01). Removal of the endothelium markedly p

Abstract:
A fourth case of displacement of one ring of an intraluminal graft is reported. This occurred in a woman who was operated on for acute dissection of the aorta. The displacement happened 8 h after surgery and produced acute obstruction of the ascending aorta. Restoration of the proximal ring of the graft into its correct position was successful.

Abstract:
We describe a neonate with an unusual vascular ring formed by a right-sided aortic arch with associated coarctation and distal hypoplasia in the presence of an aberrant left subclavian artery. The descending aorta traveled behind the esophagus to descend on the left side of the spine. A left ductus arteriosus connected to the descending aorta completing the vascular ring, with notable esophageal compression. Surgical correction was accomplished through median sternotomy, resection of the hypoplastic circumflex arch, aortic arch advancement, and end-to-side anastomosis.

Aortic rings were prepared from age-matched male and female Sprague-Dawley rats and mounted for isometric tension recording.

The circumflex aorta is a rare type of true vascular ring anomaly. It consists of a retroesophageal right aortic arch, a left-sided descending thoracic aorta, and a left-sided ligamentum arteriosum. The “aortic uncrossing procedure” described by Planché and Lacour-Gayet is the procedure of choice for managing this aortic anomaly in patients with a biventricular heart. The presence of a circumflex aorta in a patient with heterotaxy syndrome and univentricular congenital heart disease requiring Norwood palliation is highly unusual.

Supravalvar aortic stenosis, aortic arch anomalies, and coarctation of the aorta are lesions involving the ascending and descending aortas, which can cause obstruction to left ventricular forward flow. In some cases, they can be associated with an anomalous borderline left ventricle. Obstructive lesions impose an increased afterload on the left ventricle and, if severe and untreated, result in hypertrophy and eventual dilatation and failure of the left ventricle.

In addition to circumferential tensile stress caused by luminal pressure, arterial wall contains circumferential residual stress with compressive and tensile components with maximum values on intima and adventitia respectively. The compressive residual stress component compensates part of maximum tensile stress, and therefore decreases severity of tension on endothelial lining. If an arterial ring is cut in
