We report the case of a 36-year-old female whose dysphagia revealed a congenital anomaly of the thoracic aorta: the right aortic arch with mirror image branching. This is a rare embryonic developmental anomaly where the aorta wraps around the right bronchus and the supra-aortic trunks emerge from the arch in the opposite order to normal. Most of the patients are asymptomatic unless there is a significant compression of mediastinal structures. Major compression of the esophagus or trachea, aneurysmal disease, dissection of the thoracic aorta, or the presence of a Kommerell diverticulum larger than 2 cm may require a surgical repair. There is no standard treatment and it must be adapted to the clinical presentation and the anatomic configuration of each patient. Our patient did not receive any treatment for her condition.


Nous rapportons le cas d'une patiente de 36 ans dont le tableau de dysphagie a permis de mettre en évidence une anomalie congénitale de l'aorte thoracique : l'arc aortique droit avec image en miroir. Il s'agit d'une anomalie de développement embryonnaire rare où l'aorte s'enroule autour de la bronche souche droite et où les troncs supra-aortiques émergent de la crosse dans l'ordre inverse et opposé à la normale. La grande majorité des patients est asymptomatique, à moins qu'il existe une compression des structures médiastinales. Une compression majeure de l'oesophage ou de la trachée, une maladie anévrismale, une dissection de l'aorte thoracique ou la présence d'un diverticule de Kommerell de plus de 2 cm peuvent justifier une sanction chirurgicale. Il n'y a pas de traitement standard et celui-ci doit être adapté à la présentation clinique et à la configuration anatomique du patient. Notre patiente n'a bénéficié d'aucun traitement pour son affection.

In the past 20 years, there has been a real development of aortic valve repair techniques with an increasing number of publications describing the long-term benefits of aortic valve repair in terms of survival, freedom from major adverse valve related-events and reoperations. Aortic valve repair can now be considered as a valuable alternative to prosthetic valve replacement in patients with dystrophic ascending aorta pathology associated or not to aortic insufficiency with pliable leaflets. In this paper, the authors describe the state of the art of aortic valve repair and present their clinical experience with aortic valve repair surgery in the university hospital center of Liege from April 2021 to September 2022.


Les techniques de réparation de la valve aortique se sont considérablement développées ces 20 dernières années. Plusieurs publications confirment les bénéfices à long terme de ces techniques en termes de survie, d'absence de complications majeures et de réinterventions pour récidive d'insuffisance aortique. La réparation de la valve aortique apparaît ainsi comme une véritable alternative au remplacement valvulaire aortique prothétique chez certains patients qui présentent une pathologie dystrophique de l'aorte ascendante associée ou non à une insuffisance aortique sur valve souple. Dans cet article, les auteurs parcourent la littérature actuelle sur le sujet et décrivent leur expérience clinique avec la chirurgie de réparation de la valve aortique au sein du centre hospitalier universitaire de Liège d'avril 2021 à septembre 2022.

Atherosclerosis is the principal cause of mortality in industrialized countries. Its development is influenced by several mediators of which thromboxane A(2) (TXA(2)) and 8-iso-PGF(2α) have recently received a lot of attention. This study aimed to investigate the effect of a dual thromboxane synthase inhibitor and thromboxane receptor antagonist (BM-573) and ASA on lesion formation in apolipoprotein E-deficient mice. The combination of ASA and BM-573 was also studied. Plasma measurements demonstrated that the treatments did not affect body weight or plasma cholesterol levels. BM-573, but not ASA, significantly decreased atherogenic lesions as demonstrated by macroscopic analysis. Both treatments alone inhibited TXB(2) synthesis but only BM-573 and the combination therapy were able to decrease firstly, plasma levels of soluble intracellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) and secondly, the expression of these proteins in the aortic root of Apo E. These results were confirmed in endothelial cell cultures derived from human saphenous vein endothelial cells (HSVECs). In these cells, BM-573 also prevented the increased mRNA expression of ICAM-1 and VCAM-1 induced by U-46619 and 8-iso-PGF(2α). Our results show that a molecule combining receptor antagonism and thromboxane synthase inhibition is more efficient in delaying atherosclerosis in Apo E(-/-) mice than sole inhibition of TXA(2) formation.
