Imaging plays a crucial role in the postoperative monitoring of thoracic aortic repairs. With the development of multiple surgical techniques to repair the ascending aorta and aortic arch, it can be a daunting challenge for the radiologist to diagnose potential pathologies in this sea of various techniques, each with their own normal postoperative appearance and potential complications. In this paper, we will provide a comprehensive review of the postoperative imaging in the setting of thoracic aortic repairs, including the role of imaging, components of thoracic aortic repairs, the normal postoperative appearance, and potential complications.

Several techniques for the surgical correction of congenital supravalvular aortic stenosis have been devised. We describe the step-by-step surgical approach of a slide aortoplasty to correct localized supravalvular aortic stenosis in a 3-year-old child with Williams syndrome.

Background: The decrease in S-nitrosoglutathione reductase (GSNOR) leads to an elevation of S-nitrosylation, thereby exacerbating the progression of cardiomyopathy in response to hemodynamic stress. However, the mechanisms under GSNOR decrease remain unclear. Here, we identify NEDD4 (neuronal precursor cell expressed developmentally downregulated 4) as a novel molecule that plays a crucial role in the pathogenesis of pressure overload-induced cardiac hypertrophy, by modulating GSNOR levels, thereby demonstrating significant therapeutic potential.

Aortic stenosis (AS) was historically considered a disease of the left side of the heart, with the main pathophysiological impact being predominantly on the left ventricle (LV). However, progressive pressure overload in AS can initiate a cascade of extra-valvular myocardial remodeling that could also precipitate maladaptive alterations in the structure and function of the right ventricle (RV). The haemodynamic and clinical importance of these changes in patients with AS have been largely underappreciated in the past.

Background: Data supporting the use of transcatheter aortic valve replacement (TAVR) for bicuspid aortic valve (BAV) is limited compared to tricuspid aortic valve (TAV) anatomy, as the BAV anatomy poses unique challenges to prosthesis expansion and symmetric deployment.
Aims: We aim to compare the acute recoil and asymmetry of the SAPIEN-3 valve between BAV and TAV anatomies and their impact on procedural outcomes.
Methods: We conducted a single-center study of patients who underwent TAVR with the SAPIEN-3 valve.

Thoracic and abdominal aortic aneurysm poses a substantial mortality risk in adults, yet many of its underlying factors remain unidentified. Here, we identify mitochondrial nicotinamide adenine dinucleotide (NAD)⁺ deficiency as a causal factor for the development of aortic aneurysm. Multiomics analysis of 150 surgical aortic specimens indicated impaired NAD salvage and mitochondrial transport in human thoracic aortic aneurysm, with expression of the NAD transporter SLC25A51 inversely correlating with disease severity and postoperative progression.
