In this study, an image-based morphometry toolset quantifying geometric descriptors of the left ventricle, aorta and their coupling is applied to investigate whether morphological information can differentiate between subjects affected by diastolic dysfunction (patient group) and their age-matched controls (control group). The ventriculo-aortic region of 20 total participants (10 per group) were segmented from high-resolution 3D magnetic resonance images, from the left ventricle to the descending aorta. Each geometry was divided into segments in correspondence of anatomical landmarks...

Background  An aberrant right subclavian artery (RSA) or arteria lusoria is the most common congenital abnormality of the aortic arch with an incidence of 0.3 to 3.0%. Case Description  We report a case of a perforated aneurysmal aberrant RSA, managed using a hybrid approach. Conclusion  In emergency cases with acute bleeding, we recommend an endovascular approach to avoid the lethal sequel of arterial leakage. Whenever possible, the pulsatile blood flow to the right arm should be restored. Management should be tailored to the nature of the aneurysmal aberrant RSA, patient's comorbidities, and concomitant lesions...

The right-side aortic arch may be associated with aberrant left subclavian artery, in some cases this artery originates from an aneurismal dilatation of the aorta called Kommerell diverticulum. We report 2 cases of vascular ring formed by a right-side aortic arch, anomalous left subclavian artery, Kommerell's diverticulum and left patent ductus arteriosus.

Abdolrahim Ghasemi, Ali Reza Serati, Sepideh Emami, Mohammad Reza Movahed
Disconnection of the subclavian artery from the aortic arch, defined as isolation, is a rare aortic arch anomaly. In this anomaly, loss of continuity between one subclavian artery and the aorta with persistent connection to the homocollateral pulmonary artery through a patent or remnant ductus arteriosus is present. This isolation is almost always seen on the side contralateral to the aortic arch position. Complex cardiac and genetic anomalies are frequently associated with the isolation of a subclavian artery...

Rationale: Diverse B cell responses and functions may be involved in atherosclerosis. Protective antibody responses, such as those against oxidized lipid epitopes, are thought to mainly derive from T cell-independent innate B cell subsets. In contrast, both pathogenic and protective roles have been associated with T cell-dependent antibodies and their importance in both humans and mouse models is still unclear. Objective: To specifically target antibody production by plasma cells and determine the impact on atherosclerotic plaque development in mice with and without CD4+ T cells...

Descending necrotizing mediastinitis (DNM) is a life-threatening disease which often develops from a purulent infection of the oral cavity and is associated with high rates of mortality. Here we report the case of a young patient who died from an aortic arch rupture in context of DNM developed from an odontogenic infection caused by Prevotella buccae. Based on the current knowledge on this very rare vascular complication, we discuss factors that may have contributed to this fatal issue and future issues to optimize care provided to patients...

We report a 78-year-old man who presents progression of his aneurysmatic pathology with previous abdominal infrarenal aortic surgery 20 years later. The computed tomography (CT) scan showed proximal degeneration of the infrarenal aorta, left iliac aneurysm and a new descending thoracic aneurysm close to the aortic arch. The surgical treatment was staged in two times due to the evolution of the aneurysm measures. First, the thoracic and the infrarenal aneurysms were covered each one with endoprosthesis. Four years later the iliac disease was solved with a branched specific iliac endograft...

Predictive risk models help improve decision making, information to our patients and quality control comparing results between surgeons and between institutions. The use of these models promotes competitiveness and led to increasingly better results. All these virtues are of utmost importance when the surgical operation entails high-risk. Although proximal aortic surgery is less frequent than other cardiac surgery operations, this procedure itself is more challenging and technically demanding than other common cardiac surgery techniques...
