Nontuberculous mycobacteria cause severe pulmonary, vascular graft, and bloodstream infections after cardiac surgery. Patient prognosis remains poor because of delays in diagnosis and treatment. Complicated aortic root infections caused by nontuberculous mycobacteria have been mostly fatal. We describe a case of a 50-year-old man who developed an invasive Mycobacterium chimaera infection with an aortic root pseudoaneurysm after a Bentall-de Bono procedure for a Stanford type A aortic dissection.
Objective: Single-center studies have suggested that solid organ transplant recipients are at increased risk for arterial aneurysms. Moreover, they describe a more aggressive natural history with increased rates of expansion and rupture. In this exploratory analysis, we aim to assess the frequency of arterial aneurysms in solid organ transplant recipients using a large-scale national database.

Rheumatoid arthritis (RA) and cardiovascular disease (CVD) are both the chronic inflammatory disease. To investigate the influence of secondary atherosclerosis on arthritis mice, we treated the ApoE mice with K/BxN serum and high fat diet (HFD), and subsequently assessed the phenotypes as well as immune profiles of K/BxN serum and HFD induced ApoE mice. We found that HFD treatment aggravated the hyperlipidemia, atherosclerotic lesions, ankle swelling and arthropathy of mice.

Background: Thoracic aortic dissection (TAD) is an uncommon complication in patients with Tetralogy of Fallot (TOF). Information concerning risk factors for TAD in patients with TOF is very limited.
Methods: We report a case of Stanford type A TAD in a female patient with previously repaired TOF.
Background: Double aortic arch (DAA) with type B aortic dissection in adults is a rare aortic vascular disease. The abnormal anatomical structure of the aortic arch in such patients presents significant challenges in the selection of surgical approaches, and there is a notable lack of exploration into endovascular repair approaches that simultaneously preserve asymptomatic vascular rings.
Case Description: A 43-year-old female patient was admitted due to recurrent chest and back pain lasting for over a month.
Background: Bicuspid aortic valve (BAV) is the most common congenital heart defect (reported incidence of 0.5%-2%) and is commonly associated with proximal aortic dilation. Patients with severe aortic stenosis (AS) of BAV have been shown to have worse pre-operative left ventricular (LV) function as well as a higher incidence of post-operative heart failure hospitalization when compared with analogous patients with tri-leaflet aortic valve disease.
