Marfan syndrome (MFS) is characterized by the formation of ascending aortic aneurysms resulting from altered assembly of extracellular matrix fibrillin-containing microfibrils and dysfunction of TGF-β signaling. Here we identify the molecular targets of redox stress in aortic aneurysms from MFS patients, and investigate the role of NOX4, whose expression is strongly induced by TGF-β, in aneurysm formation and progression in a murine model of MFS. Working models included aortae and cultured vascular smooth muscle cells (VSMC) from MFS patients, and a NOX4-deficient Marfan mouse model (Fbn1C1039G/+ -Nox4-/- )...

OBJECTIVE: A new endovascular tool, the Liungman Guidewire Fixator, has been developed to simplify endovascular treatment in complex aortic aneurysms. The device has been extensively tested in bench models and animal trials. To verify the safety and functionality demonstrated in the porcine model, the device was tested in ten patients undergoing endovascular aortic repair (EVAR) or fenestrated endovascular aortic repair (f-EVAR) treatment for abdominal aortic aneurysm. METHODS: The Liungman Guidewire Fixator consists of a braided stent-like, cylindrical structure with conical ends and a central channel for a 0...

OBJECTIVES: Chronic, post-dissection thoraco-abdominal aortic aneurysms (TAAAs) are increasingly being treated by (hybrid) endovascular means. Although it is less invasive, thoracic endovascular aortic repair is technically complex with the risk of incomplete aneurysm exclusion, necessitating frequent reinterventions with potentially reduced long-term outcomes. The aim of this study was to evaluate contemporary early and late outcomes after open surgical repair of post-dissection TAAA...

PURPOSE: To report the endovascular treatment of a spontaneous iliac artery dissection (IAD) involving iliac bifurcation, complicated by a type B intramural aortic hematoma (IMH). CASE REPORT: A 38-year-old female patient came to our institution referring an acute ascending back pain. The angioCT-scan showed the presence of a retrograde right IAD with entry tear at the iliac bifurcation and a concomitant aortic IMH. After hypogastric embolization with a vascular plug, self-expanding stent-graft was placed to cover the iliac entry tear...

BACKGROUND: Use of 4-dimensional flow magnetic resonance imaging (4D-flow MRI) derived wall shear stress (WSS) heat maps enables identification of regions in the ascending aorta with increased WSS. These regions are subject to dysregulation of the extracellular matrix and elastic fiber degeneration, which is associated with aortic dilatation and dissection. PURPOSE: To evaluate the effect of the presence of aortic valve stenosis and the aortic diameter on the peak WSS and surface area of increased WSS in the ascending aorta...

" The major goal of surgery for acute type A aortic dissection is to have an alive patient. " This motto still remains the most important directive. However, also depending onto the extent of the underlying pathology and consecutively depending onto the extent of primary surgery, there is and will be need for additional classical surgical or interventional treatment sooner or later during follow-up in a substantial number of patients having had surgery for acute type A aortic dissection. This article shall guide the interested reader through the underlying mechanisms as well as treatment options in patients with chronic type B "residual" after type A repair and shall finally suggest preventive strategies to reduce the occurrence of this pathology to a minimum...

Dilatation of aortic root may distort the tricuspid annulus. We experienced a case of chronic aortic dissection presented with tricuspid regurgitation. Chest computed tomography revealed an enlarged ascending aorta displacing the right heart. The patient successfully underwent replacement of the aorta and tricuspid annuloplasty with a prosthetic annulus.

INTRODUCTION: Coronary artery disease (CAD) not amenable to revascularisation indicates that the coronary arteries have severe diffuse lesions or calcifications, or that CAD is complicated with severe multiple-organ disease. Currently, Western medicines available for the treatment of CAD not amenable to revascularisation are limited. Shexiang Baoxin Pill (SBP), a type of Chinese patent medicine, has been widely used to treat CAD in China for many years. Previous studies have shown that long-term administration of SBP (1-2 pills three times daily, for at least 6 months) for treatment of CAD is effective and safe, with a significant, long-term effect...

Aneurysm-osteoarthritis syndrome is a recently discovered inherited autosomal dominant connective tissue disease caused by SMAD3 mutations. Aneurysm-osteoarthritis syndrome is responsible for 2% of familial thoracic aortic aneurysms and dissections and is characterised by aneurysms, dissections, and tortuosity throughout the arterial tree in combination with osteoarthritis. Early-onset osteoarthritis is present in almost all patients. We present the case of a non-syndromic young boy with SMAD3 mutation isolated from the dilated aortic root and ascending aorta without osteoarthritis...

BACKGROUND AND PURPOSE: A recurrent duplication of chromosome 16p13.1 was associated with aortic dissection as well as with cervical artery dissection. We explore the segregation of this duplication in a family with familial aortic disease. METHODS: Whole exome sequencing (WES) analysis was performed in a patient with a family history of aortic diseases and ischemic stroke due to an aortic dissection extending into both carotid arteries. RESULTS: The index patient, his affected father, and an affected sister of his father carried a large duplication of region 16p13...

Marfan syndrome (MFS) is a genetic disorder that frequently leads to aortic root dissection and aneurysm. Despite promising preclinical and pilot clinical data, a recent large-scale study using antihypertensive angiotensin II (AngII) receptor type 1 (ATR1) blocker losartan has failed to meet expectations at preventing MFS-associated aortic root dilation, casting doubts about optimal therapy. To study the deleterious role of normal ATR1 signaling in aortic root widening, we generated MFS mice lacking ATR1a expression in an attempt to preserve protective ATR2 signaling...
