Early impact of aortic wrapping on patients undergoing aortic valve replacement with mild to moderate ascending aorta dilatation

Journal of Cardiothoracic Surgery, 2010
Background The management of mild to moderate dilatation of the ascending aorta of less than 5 cm is controversial, particularly when concomitant surgical correction of aortic valve is required.

Expanding the Minimally Invasive Approach towards the Ascending Aorta—A Practical Overview of the Currently Available Techniques

Medicina, 2023
Minimally invasive techniques have gained immense importance in cardiovascular surgery. While minimal access strategies for coronary and mitral valve surgery are already widely accepted and often used as standard approaches, the application of minimally ...

Association of Cystic Medial Necrosis of the Aorta and Undiagnosed Thyroiditis [Scripta Medica] [PDF]

, 1977
We have recently seen two patients with cystic medial necrosis of the aorta. The first patient died of a dissecting aneurysm of the thoracic aorta. At autopsy, classical Hashimoto’s thyroiditis was discovered.

Mycotic pseudoaneurysm of the ascending aorta [PDF]

European Heart Journal - Cardiovascular Imaging, 2014
A 49-year-old man consulted for progressive dyspnoea and bilateral lower extremity oedema. His history included a hospital admission because of a multi-resistant Escherichia coli septicaemia 3 years before. Transthoracic echocardiography revealed a calcified mass adjacent to the aortic root ( Panel A ).

Microphysiological Uremia Model Reveals Biophysical Potentiators of Vascular Dysfunction

Advanced Science, EarlyView.
A microfluidic platform of engineered blood vessels is developed to study the role of mechanical forces in immune cell adhesion and extravasation in uremic microenvironments. Elevated pressure increases monocyte activity, with ICAM‐1 as a key driver. Matrix density influences monocyte phenotypes, but the uremic environment consistently promoted a pro ...

MCP-1, ICAM-1 and VCAM-1 are present in early aneurysmal dilatation in experimental rats.

Folia Histochemica et Cytobiologica, 2010
Recent studies have suggested that inflammation actively participates in ascending aortic aneurysm formation. The aim of the present study was to evaluate the expression changes of adhesion molecules and MMPs in an experimental model of ascending aortic ...

Ascending aorta measurements as assessed by ECG-gated multi-detector computed tomography: a pilot study to establish normative values for transcatheter therapies [PDF]

, 2018
The aim of this study was to provide an insight into normative values of the ascending aorta in regards to novel endovascular procedures using ECG-gated multi-detector CT angiography.

Patient-specific computational fluid dynamics-assessment of aortic hemodynamics in a spectrum of aortic valve pathologies. [PDF]

, 2016
OBJECTIVES: The complexity of aortic disease is not fully exposed by aortic dimensions alone, and morbidity or mortality can occur before intervention thresholds are met.

Rictor Ameliorates Acute Antibody‐Mediated Rejection Following Kidney Transplantation by Suppressing Macrophage M1 Polarization Through p65‐NLRP3 Axis

Advanced Science, EarlyView.
This study elucidates the critical role of Rictor in macrophage activation in acute antibody‐mediated rejection (ABMR). Rictor increases K48‐linked ubiquitination of p65 by upregulating E3 ubiquitin ligase SOCS1, inhibiting transcriptional levels of NLRP3 and inflammasome activation.

Demographical and Clinical Factors Predictive for Aortic Dilatation. When should we be Concerned about the Size?

Reviews in Cardiovascular Medicine
Background: Thoracic aortic aneurysms are often an accidental finding and result from a degenerative process. Medical therapy includes pharmacological control of arterial hypertension and smoking cessation, that slows the growth of aneurysms.
