One of the approaches to treatment of the aortic root aneurysms combined with aortic insufficiency is valve-sparing aortic root replacement. An analysis of immediate and long-term results dealt with 19 operations of replacement of the ascending parts of the aorta with sparing the aortic valve by the David I modified technique. The results demonstrated effectiveness and relative safety of this method of correction. At the long-term period 3 patients (16%) showed the II degree aortic regurgitation, in the other patients it was not higher than I degree. The improved David I technique is thought to be optimal in patients with the aortic root aneurysms, aortic insufficiency and unaltered aorta valve cusps.

Background: Marfan syndrome (MFS) is an inherited disorder caused by mutations in the gene encoding fibrillin-1, a matrix component of extracellular microfibrils. The main cause of morbidity and mortality in MFS is thoracic aortic aneurysm and dissection, but the underlying mechanisms remain undetermined.
Methods: To elucidate the role of endothelial XOR (xanthine oxidoreductase)-derived reactive oxygen species in aortic aneurysm progression, we inhibited in vivo function of XOR either by endothelial cell (EC)-specific disruption of the gene or by systemic administration of an XOR inhibitor febuxostat in MFS mice harboring the missense mutation p.

Marfan syndrome (MFS), an inherited connective tissue disorder, is caused by a mutation in the FBN1 gene. MFS is characterized by complex manifestations involving musculoskeletal, cardiovascular, and ocular systems. The usual presentation for suspecting diagnosis in an individual with aortic root disease is tall stature in addition to other features that fulfill Ghent criteria.

Background: Aortic dissection occurs rarely during pregnancy but carries a significantly high vital risk for both the mother and the fetus. Early diagnosis and treatment are critical for a successful outcome.
Case Presentation: A 32-year-old pregnant woman at 31 weeks of gestation began experiencing shortness of breath, chest pain, and palpitations, which were attributed to an anxiety disorder she had been previously diagnosed with.

Purpose: The underlying mechanism why segmentectomy has demonstrated the non-inferiority to lobectomy in several randomized trials remains unclear. Computed tomography (CT)-measured pulmonary artery (PA) enlargement reflects PA pressure and predicts the prognosis of certain respiratory diseases. We compared the preoperative and postoperative PA diameter to the ascending aorta diameter (PA/A) ratio, investigating its impact on right ventricular function in lung resection.
