AIMS: In aortic stenosis (AS), both reduced systemic arterial compliance and increased valvular load have been shown to contribute to impaired left ventricular (LV) function. However, the relationship between LV function and aortic stiffness has not yet been investigated. We aimed to assess the relationship between aortic stiffness and LV ...

We previously observed that focal hepatic venous outflow obstruction recovered spontaneously by the formation of sinusoidal canals in a rat model of portal hyperperfusion. We aimed to investigate whether the lack of hepatic arterial perfusion aggravates parenchymal damage, decelerates recovery and influences the formation of sinusoidal canals after focal hepatic ...

A disintegrin and metalloprotease with thrombospondin type 1 repeats-13 (ADAMTS13) inhibits platelet aggregation and arterial thrombosis by cleavage of von Willebrand factor. However, the structural components of ADAMTS13 required for inhibition of arterial thrombosis are not fully defined. Using recombinant proteins and a murine model, we demonstrated that an ADAMTS13 ...

Lenalidomide is a derivative of thalidomide and is FDA-approved for the treatment of myelodysplastic syndrome and, in combination with dexamethasone, for the treatment of relapsed multiple myeloma. Pulmonary toxicity with thalidomide is a recognized potential complication; however, there have only been two case reports in the literature of lenalidomide-associated pulmonary ...

Left Ventricular Assist Devices (LVADs) are implantable mechanical pumps that temporarily aid the function of the left ventricle. The use of LVADs has been associated with thrombus formation next to the aortic valve and close to the anastomosis region, especially in patients in which the native cardiac function is negligible ...

The aim of the present study was to investigate the influence of a decellularization protocol on the structure and the mechanical behavior of small-diameter (<6 mm) tibial calf arteries and veins. Calf vessels were decellularized by a detergent-enzymatic method (DEM), partially hydrolyzed with trypsin and subsequently cross-linked using poly(ethylene glycol) diglycidyl ...

Stent fracture with pseudoaneurysm formation in the femoropopliteal artery has uncommonly been reported. We present the case of a 72-year-old man with a fracture of self-expanding nitinol stent and a pseudoaneurysm formation in the suprageniculate popliteal artery. The popliteal artery was successfully reconstructed with a small saphenous vein graft interposition.

Transcatheter aortic valve implantation (TAVI) was introduced in 2006 as an alternative for surgical aortic valve replacement (SAVR) as treatment for patients with aortic stenosis. Endocarditis after TAVI has been anecdotally reported, but concerns aroused because SAVR is often needed to explant the endocarditic valve in a high risk patient ...

Unlike high-grade stenosis, dissections of craniocervical arteries are a rare cause of cerebrovascular infarction. If the internal carotid artery (ICA) dissection is verified by duplex scanning or computed tomography angiography (CTA), the therapies of choice are antiplatelet and anticoagulation drugs, and surgical treatment is rarely performed. However, despite distinct clinical ...

Diagnostic delay in patients suffering massive pulmonary embolism (PE) on chronic thromboembolic pulmonary hypertension (CTEPH) has inevitably fatal consequences. Indications to pulmonary thromboendarterectomy (PTE) and extracorporeal membrane oxygenation (ECMO) are limited by severe comorbid conditions, some of which, as neurologic disease, absolutely contraindicate these procedures. We reported the clinical course ...

Giant intracranial aneurysms have a poor prognosis mainly due to their high risk of rupture. Because their incidence is low, clinical trial evidence for adequate treatment is lacking. The Giant Intracranial Aneurysm Registry is designed to document current treatment strategies in giant aneurysm care and to monitor the course of ...

OBJECTIVE: Total arch replacement with an elephant trunk is a standard treatment for arch aneurysm, but serious complications, such as paraplegia and peripheral embolization caused by flapping of the elephant trunk, remain. Moreover, dilation of the descending aorta and retrograde flow into the peri-graft space at the distal elephant trunk ...

Aortic stenosis is a common disorder. Aortic valve replacement is indicated in symptomatic patients with severe aortic stenosis, as the prognosis of untreated patients is poor. Nevertheless, many patients pose a prohibitively high surgical risk and are not candidates for surgical valve replacement. Transcatheter aortic valve implantation (TAVI) is a ...

Percutaneous intervention of chronic limb ischemia is often limited by vascular access especially in patients with previous surgical interventions. This warrants development of alternative endovascular techniques, particularly for patients in whom traditional ipsilateral antegrade or contralateral retrograde access has failed or is not possible. We describe a novel approach to ...

Surgical treatment of abdominal aortic aneurysm after previous pneumonectomy is a challenge because of the impaired respiratory function and increased surgical risks. Endovascular aneurysm repair in anatomically suited high-surgical-risk patients offers excellent short-term results and provides good protection from aneurysm-related death. In this article, we report a successful endovascular aneurysm ...

Aortic stenosis is currently the most predominant valvular pathology in older adults. Signs and symptoms of aortic stenosis in this age-group may be difficult to recognize due to the decreased activity associated with aging and attribution of symptoms to other conditions. Echocardiography can be very helpful in the assessment of ...

Nephrology nurses are often faced with the responsibility of triage. Shortness of breath in a patient receiving chronic dialysis is a frequently heard complaint. Clinicians, at first glance, will consider volume expansion as the probable cause for the shortness of breath, and most often, they are correct. However, for some, ...

Aortic arch replacement remains among the most technically challenging cardiovascular operations, incurring considerable risk for perioperative death and stroke. The trifurcated graft technique, in which a double Y-graft is used to connect brachiocephalic branches to the main aortic graft, was recently developed to simplify arch reconstruction, reduce embolization, and minimize ...

Patients who have had an esophagectomy with gastric pull-up are at a higher risk for perioperative pulmonary aspiration due to loss of the esophageal sphincter. Altered neck anatomy following esophagectomy may render the conventional cricoid pressure maneuver unreliable in preventing pulmonary aspiration during induction of general anesthesia. Two patients who ...

OBJECTIVES: A detailed preoperative evaluation of coronary anatomy is mandatory before surgical intervention for tetralogy of Fallot. In pediatric patients, the preoperative evaluation of coronary anatomy has relied classically on conventional angiographic analysis and, more recently, on echocardiographic analysis, which have well-known limitations and complications. Recent technological improvements allow the ...
