Although abdominal aortic aneurysms are the most common aortic pathology in the general population, the thoracic aorta is also a frequent site of aneurysms, chronic dissections, transections, and other potentially life-threatening pathologies. Not all of these lesions are amenable to endovascular repair; however, early evidence suggests that endovascular intervention in selected patients has a high rate of acute and midterm success. Indeed, the endovascular procedure reduces operating time and the need for blood transfusions and usually results in shorter intensive care unit and hospital stays compared with open surgery. In addition, overall rehabilitation is comparatively brief. Although these results are encouraging, no outcome data from randomized trials exists, and further study of the long-term efficacy and safety of endoluminal grafting is warranted.

Background: Recent studies show that hyperactivation of mTOR (mammalian target of rapamycin) signaling plays a causal role in the development of thoracic aortic aneurysm and dissection. Modulation of PP2A (protein phosphatase 2A) activity has been shown to be of significant therapeutic value. In light of the effects that PP2A can exert on the mTOR pathway, we hypothesized that PP2A activation by small-molecule activators of PP2A could mitigate AA progression in Marfan syndrome (MFS).

A patient in his early adolescence, who was treated for T5-T6 tubercular spondylodiscitis with an un-instrumented decompression, presented at 36 months post-index surgery, for post-laminectomy instability and kyphosis, after completing his requisite antitubercular treatment. He underwent thoracic posterior instrumented kyphosis correction and anterior reconstruction, with a T5-T6 partial corpectomy and corpectomy spacer placement, through a posterior midline incision. On the second postoperative day, he started complaining of pain on the left side of his chest, abdomen and left shoulder.

Background: This study aimed to investigate the demographics and to evaluate long-term outcomes of acute type A aortic dissection (ATAAD) in surgically treated patients ≤40 years in China.
Methods: This study included patients aged ≤40 with ATAAD who underwent surgical treatment at our institution between 2015 and 2019. The patients were categorized into groups according to heritable thoracic aortic disease (HTAD) presence or absence.

The contribution of sex hormones to cardiovascular disease, including arterial stiffness, is established; however, the role of sex chromosome interaction with sex hormones, particularly in women, is lagging. Arterial structural stiffness depends on the intrinsic properties and transmural wall geometry that comprise a network of cells and extracellular matrix (ECM) proteins expressed in a sex-dependent manner. In this study, we used four-core genotype (FCG) mice to determine the relative contribution of sex hormones versus sex chromosomes or their interaction with arterial structural stiffness.

Rationale And Objectives: Cardiovascular toxicity is a well-known complication of thoracic radiation therapy (RT), leading to increased morbidity and mortality, but existing techniques to predict cardiovascular toxicity have limitations. Predictive biomarkers of cardiovascular toxicity may help to maximize patient outcomes.
Methods: The machine learning optimal biomarker (OBM) method was employed to predict development of cardiotoxicity (based on serial echocardiographic measurements of left ventricular ejection fraction and longitudinal strain) from computed tomography (CT) images in patients with thoracic malignancy undergoing RT.
