The functional aortic annulus offers a clinical approach for the perioperative echocardiographer to classify the mechanisms of aortic regurgitation in acute type-A dissection. Comprehensive examination of the functional aortic annulus in this setting using transesophageal echocardiography can guide surgical therapy for the aortic root by considering the following important aspects: severity and mechanism of aortic regurgitation, extent of root dissection, and the pattern of coronary artery involvement. The final choice of surgical therapy also should take into account factors, such as patient presentation and surgical experience, to limit mortality and morbidity from this challenging acute aortic syndrome...

performing percutaneous coronary intervention (PCI) following transcatheter aortic valve implantation (TAVI) will become more frequent with the increasing use of TAVI in lower surgical risk populations. The ideal management strategy for coronary artery disease (CAD) in the setting of TAVI is not well defined and CAD is often left untreated prior to TAVI. Engaging the coronary ostia through the TAVI side cells can be challenging; techniques for rapid coronary cannulation, especially in the acute setting, need to be developed...

Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis, is a pulmonary-renal syndrome affecting small and medium sized blood vessels. The disease has a prevalence in studies ranging from 3 to 15.7 cases per 100,000, with a noted increasing incidence and prevalence in more recent studies. Pulmonary manifestations include hemorrhage, lung cavitary lesions, and pulmonary fibrosis. Within the kidney, GPA is known to cause rapidly progressive pauci-immune crescentic glomerulonephritis...

The etiology of thoracic aortic aneurysm and dissection (TAAD) is complex and heterogeneous. Emerging evidence has demonstrated that genetic causes may be a consideration in early‑onset TAAD. Owing to overlapping clinical phenotypes and the genetic heterogeneity of TAAD, it is challenging for clinicians to make a molecular diagnosis of TAAD, particularly in those who present with non‑specific syndromic features. In order to identify the causative mutation in two young patients with acute type B aortic dissection without syndromic features, whole exome sequencing (WES) was performed in the present study...

Thoracic aortic aneurysm is an indication for major cardiovascular operative procedures. The etiology is usually hypertension and/or atherosclerotic disease; reaching a certain diameter often results in acute aortic syndrome. Immunoglobulin G4-related aortitis, characterized by lymphoplasmacytic vascular tunica media induration without well-defined underlying infectious or autoimmune systemic causes, is uncommon. Histological similarity to immunoglobulin G4 disease in other organs suggests that this aortitis might be a manifestation of systemic pathology...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

Respiratory complications are a major factor contributing to postoperative morbidity and mortality, especially in patients with chronic obstructive pulmonary disease (COPD). Our objective was to compare the rate of respiratory complications in patients with COPD with severe aortic stenosis who underwent transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement (SAVR). Low-to-intermediate surgical-risk patients with moderate or severe COPD who underwent TAVI or SAVR at 2 tertiary centers were included in this study...

Alport syndrome (AS) is a genetic disorder due to inheritance of genetic mutations which lead to production of abnormal type IV collagen. AS has been associated with renal, auditory, and ocular diseases due to the presence of abnormal alpha chains of type IV collagen in the glomerulus, cochlea, cornea, lens, and retina. The resulting disorder includes hereditary nephritis, corneal opacities, anterior lenticonus, fleck retinopathy, temporal retinal thinning, and sensorineural deafness. Aortic and aortic valve pathologies have been described as extrarenal manifestations of AS in multiple case reports...

Acute aortic dissection is a rare but life-threatening condition with a lethality rate of 1 to 2% per hour after onset of symptoms in untreated patients. Therefore, its prompt and proper diagnosis is vital to increase a patient's chance of survival and to prevent grievous complications. Typical symptoms of acute aortic dissection include severe chest pain, hypotension or syncope and, hence, mimic acute myocardial infarction or pulmonary embolism. Advanced age, male gender, long-term history of arterial hypertension and the presence of aortic aneurysm confer the greatest population attributable risk...

Acute aortic syndromes are highly morbid conditions that require prompt diagnosis and management. Aortic dissections have rhythmic patterns, with notable peaks at certain points in every 24 hours as well as weekly and seasonal variations. Several retrospective studies have assessed the chronobiology of acute aortic dissections and there seems to be a winter seasonal peak and morning daily peak in incidence. Although the pathophysiology of this chronobiology is unclear, there are several environmental and physiologic possibilities...

In the setting of blunt trauma, the rapid assessment of internal injuries is essential to prevent potentially fatal outcomes. Computed tomography is a useful diagnostic tool for both screening and diagnosis. In addition to trauma, acute chest syndromes often warrant emergent computed tomographic angiography, looking for etiologies such as aortic aneurysms or complications of aortic aneurysms, or both, pulmonary emboli, as well as other acute vascular process like aortic dissection and Takayasu aortitis. With continued improvements in diagnostic imaging, computed tomographic angiography of the chest, abdominal and pelvis proves to be an effective modality to image the aorta and other major vascular structures...

INTRODUCTION: Small Aorta Syndrome (SAS) or hypoplastic aorto-iliac syndrome is a rare pathology of the aorta that affects almost exclusively young or middle-aged women and is characterized by smaller dimension of the aorta and iliac axes. Etiopathogenesis is unclear and many factors have been invoked. The smaller caliber of the aorta and iliac arteries may predispose to aorto-iliac occlusive disease development. In the past aorto-iliac endarterectomy (AE) with patch closure was utilized as an alternative to surgical bypass in order to correct steno-obstructive syndromes affecting carriers of SAS...

Aortic dissection is the most catastrophic clinical condition that involves the aorta. It has a high mortality as well as high rate of misdiagnosis due to frequent unusual presentation. Typically, it presents with acute chest, back, and tearing abdominal pain. However, it can present atypically with minimal or no pain, making diagnosis difficult. Physicians should always suspect acute aortic dissection in patients with certain clinical conditions like difficult-to-control hypertension, giant cell arteritis, bicuspid aortic valve, intracranial aneurysms, simple renal cysts, family history of aortic disease, and Marfan syndrome, especially when a patient presents with ischemic symptoms involving multiple organ without an obvious cause...
