The surgical management of the aortic arch pathologies is controversial. Primary anastomosis and patch aortoplasties combined with end-to-end anastomosis have some complications like recurrence and aneurysm formation. Surgical repair of apical muscular (Swiss-cheese) defects is also still under debate. A 6-year-old patient with diagnosis of type A aortic arch interruption and Swiss-cheese ventricular septal defect (VSD) underwent successful intracardiac repair and aortic arch reconstruction. Aortic arch reconstruction was done by end-to-side anastomosis of distal aortic archus and thoracic aorta without cardiopulmonary bypass. The anterior side of the anastomosis was augmented by using pulmonary autograft patch and this patch was extended to the inferior surface of the archus aorta. Swiss-cheese VSD was repaired with a single patch using septal obliteration technique via transatrial approach. Pulmonary autograft patch aortoplasty and end-to-side anastomosis may be an alternative surgical management for surgical repair and it may be done without the need for cardiopulmonary bypass. In these patients associated multiple apical muscular VSDs can be repaired with a single patch, septal obliteration technique.

Aim: Newborn infants with critical aortic arch obstruction are often undiagnosed at discharge, despite screening. This study investigated if adding the perfusion index improved early detection.
Methods: We retrospectively studied 38 newborn infants with critical aortic arch obstruction, who were routinely screened in 2014-2019 by 13 Swedish hospitals using pulse oximetry and the perfusion index.

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 69-year-old man with chest pain was diagnosed with acute type B aortic dissection with the entry tear located at distal arch and a distal aortic arch aneurysm. Therefore, we performed debranching thoracic endovascular aortic repair 2 weeks after type B aortic dissection onset. First, the graft was anastomosed to bilateral axillary arteries.

Background And Objective: Hemodynamic changes that lead to increased blood pressure represent the main drivers of organ damage in hypertension. Prolonged increases to blood pressure can lead to vascular remodeling, which also affects vascular hemodynamics during the pathogenesis of hypertension. Exercise is beneficial for relieving hypertension, however the mechanistic link between exercise training and how it influences hemodynamics in the context of hypertension is not well understood.

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.
