Atherosclerosis, degenerative aortic stenosis and statins

2009

Aortic stenosis is the most common valvular heart disease among adult subjects in western countries The current treatment for aortic stenosis is aortic valve replacement. The possibility of a medical treatment that can slow the progression of aortic stenosis is very fascinating and statins have been tested to reduce the progression of degenerative aortic stenosis (DAS). The rationale for statin treatment in DAS has a deep pathophysiological substrate, in fact inflammation and lipid infiltration constitute the same histopathological pattern of both aortic stenosis and atherosclerosis and these two conditions have the same risk factors. Whether retrospective studies have shown some efficacy o…

Three-dimensional parametric modeling of bicuspid aortopathy and comparison with computational flow predictions

2017

Bicuspid aortic valve (BAV)-associated ascending aneurysmal aortopathy (namely "bicuspid aortopathy") is a heterogeneous disease making surgeon predictions particularly challenging. Computational flow analysis can be used to evaluate the BAV-related hemodynamic disturbances, which likely lead to aneurysm enlargement and progression. However, the anatomic reconstruction process is time consuming so that predicting hemodynamic and structural evolution by computational modeling is unfeasible in routine clinical practice. The aim of the study was to design and develop a parametric program for three-dimensional (3D) representations of aneurysmal aorta and different BAV phenotypes starting from s…

TCT-34 Prediction of acute kidney injury after TAVR by new biomarkers

2017

Acute kidney injury (AKI) is a common complication after transcatheter aortic valve replacement (TAVR) and is associated with increased morbidity and mortality. Routinely used biomarkers such as creatinine show a diagnostic gap in the first hours after kidney injury. Thus, new biomarkers for earlier

The Role of Small, Dense Low-Density-Lipoproteins in Non-Coronary Forms of Atherosclerosis

2008

Small, dense low density lipoproteins (LDL) are associated with increased risk for cardiovascular disease and seem to be an important predictor of cardiovascular events and progression of coronary artery disease. In addition, the predominance of small dense LDL has been accepted as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III). Less data is available on the role of LDL size in the prevention of vascular diseases, including peripheral arterial disease, carotid artery disease and abdominal aortic aneurysm. The NCEP-ATP III stated that clinical non-coronary atherosclerosis carries a risk for coronary heart disease …

Trans-limb embolization for treatment of Type 2 endoleak post EVAR: Case report

2021

Introduction Type 2 endoleaks (T2EL) occur after 10%–25% of endovascular abdominal aortic aneurysm repairs and increase the risk factor of endograft repair failure and rupture. Herein we report a case of endovascular treatment of T2EL where we performed a trans-limb embolization. Presentation of case A 63-years-old male previously treated for AAA with endovascular aortic aneurysms repair (EVAR), showed an angio-CT scan followup with a type 2 endoleak fed from inferior mesenteric artery (AMI) with growth of AAA greater of 1 cm than preoperative CT-scan and increase of chronic lumbar pain. Due to high risk of rupture was performed a trans-limb embolization with complete sealing. The 6 months …

Current role of the chimney technique in the treatment of complex abdominal aortic pathologies: A position paper from the PERICLES Registry investiga…

2020

Historically, chimney/snorkel endovascular aortic repair (Ch-EVAR) emerged as a rescue technique to revascularize and/or preserve inadvertently covered critical branch vessels during infrarenal aortic endografting. Next, in its evolutionary path, Ch-EVAR offered a viable treatment option for complex aortic repair, and particularly in situations where fenestrated/ branched EVAR was not a therapeutic option due to the lack of availability and/or anatomical constraints. In this context, this technique offered distinct advantages such as off-the-shelf availability, straightforward implantation techniques, and lower resource use-intensity enabling performance by a large number of operators manag…

Chimney Technique with Nellix EndoVascular Aneurysm Sealing System in a Patient with Single Kidney and Juxtarenal Abdominal Aortic Aneurysm

2016

AbstractWe present a saccular asymptomatic juxtarenal abdominal aortic aneurysm in a 70-year-old male with a very short left renal artery supplying the only kidney. The case was successfully treated with the Nellix EndoVascular Aneurysm Sealing system combined with a chimney technique.

Endovascular Treatment of Spontaneous and Isolated Infrarenal Acute Aortic Syndrome with Unibody Aortic Stent-Grafts

2020

Abstract Introduction Spontaneous acute aortic syndrome (IAAS) is rarely localized in the infrarenal aorta. The endovascular approach is preferred over conventional open surgery with fewer complications. However, dedicated endovascular devices for IAAS treatment are unavailable. The aim was to report a large single-center experience using unibody stent-grafts to address IAAS. Methods From April 2016 to March 2019, a retrospective analysis of patients presenting spontaneous and isolated IAAS was performed. Patients addressed with the unibody stent-graft (AFX endovascular AAA system; Endologix Inc., Irvine, CA) were included in the study. Indications to IAAS treatment were persistent symptoms…
