Introduction: Infective thoracic aortic aneurysms are uncommon, especially presenting with haemoptysis.
Case Presentation: We report the case of an 81-year-old male who presented with fever and pleuritic chest pain and was initially misdiagnosed with community-acquired pneumonia. A CT scan later revealed a saccular, ruptured thoracic aortic aneurysm. Despite antibiotic therapy, the patient developed haemoptysis, necessitating thoracic endovascular aortic repair (TEVAR). Post-procedure, the patient showed significant clinical improvement and was discharged in stable condition 45 days later.
Conclusions: Infected thoracic aortic aneurysms presenting as haemoptysis are exceptionally rare but life-threatening. Early clinical suspicion (manifested by haemoptysis, fever and thoracic pain) is essential, particularly in patients with risk factors such as immunosuppression or previous infections. This case emphasizes the importance of prompt diagnosis and intervention, along with the use of appropriate imaging techniques to reduce morbidity and mortality associated with this rare yet severe condition.

Background: This study describes in detail the clinical burden of malperfusion associated with acute Type A aortic dissection (ATAAD) in a large, national cohort and the effect of treatment strategy on outcomes.
Methods: All patients undergoing repair of ATAAD between 2017 and 2020 in the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database were studied. Malperfusion was defined using STS definitions based on imaging or surgeon's evaluation.

The dissection of the aorta is a serious and potentially fatal consequence of cocaine use. Nonetheless, the underlying mechanisms and characteristics of this phenomenon remain to be deeply studied. The autopsy case of a 46-year-old white male found irresponsive and unconscious in his house and had a history of abusing cocaine is presented.

Previous studies have shown that apo C3 is abundant in the plasma exosomes of patients with aortic dissection (AD), but its specific role in AD remains unclear.
Methods And Results: In vivo, adeno-associated virus was used to knock down hepatic apo C3 expression in an AD mouse model to assess the impact of liver-derived apo C3 on the development of AD.
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.
