The role of the vascular surgeon in transcatheter aortic valve implantation.

Background: Transcatheter aortic valve implantation (TAVI) has become the standard treatment for severe aortic valve stenosis in patients at increased surgical risk. Percutaneous transfemoral (TF) is the access of choice due to its reduced invasiveness and perioperative morbidity/mortality compared with the trans-axillary, aortic, and apical routes. On the other hand, vascular access complications (VACs) of the TF access are associated with prolonged hospitalization, 30-day, and 1-year mortality.

A systematic review and meta-analysis of the occurrence of spinal cord ischemia after endovascular repair of thoracoabdominal aortic aneurysms.

Objective: The rate of endovascular repair of thoracoabdominal aortic aneurysms (TAAA-ER) has increased considerably in recent years. Although the mortality and morbidity rates have improved, the incidence of spinal cord ischemia (SCI) has not declined significantly. The aim of the present systematic review and meta-analysis was to examine the SCI rates with respect to the efficacy of the different approaches.

Clamped Carotid Dissection Can Reduce Postoperative Stroke After Carotid Endarterectomy.

The outcomes of carotid endarterectomy (CEA) are constantly reported in a multitude of studies; however, the specific causes of perioperative stroke have been scarcely investigated. The aim of the present study was to analyze and categorize the causes of perioperative strokes after CEA. All CEAs performed from 2006 to 2019 in a single center were collected.

Computational Fluid Dynamics Modeling of Proximal Landing Zones for Thoracic Endovascular Aortic Repair in the Bovine Arch Variant.

Background: To assess the endograft displacement forces (DF), which quantify the forces exerted by the pulsatile blood flow on the vessel wall and transmitted on the terminal fixation site of the endograft after its deployment in proximal landing zones (PLZs) of the bovine aortic arch variant.

Methods: Thirty healthy aortic computed tomographic angiographies of subjects with bovine arch configuration (10 per type of arch, I-III) were selected for the purpose of the study. A 3-dimensional model of the aortic arch lumen was reconstructed.

Geometric Pattern of Proximal Landing Zones for Thoracic Endovascular Aortic Repair in the Bovine Arch Variant.

Objective: The aim was to investigate whether the "bovine" aortic arch (i.e. arch variant with a common origin of the innominate and left carotid artery (CILCA)) is associated with a consistent geometric configuration of proximal landing zones for thoracic endovascular aortic repair (TEVAR).

Aortic arch variant with a common origin of the innominate and left carotid artery as a determinant of thoracic aortic disease: a systematic review and meta-analysis.

The aim of this study was to investigate whether the 'bovine' arch [i.e. arch variant with a common origin of the innominate and left carotid artery (CILCA)] is associated with an increased risk of thoracic aortic disease (TAD).

Differences in Biomarkers Pattern Between Severe Isolated Right and Left Ventricular Dysfunction After Cardiac Surgery.

Objective: To find out if there are any differences in biomarkers between severe isolated right ventricular (RV) dysfunction and severe isolated left ventricular (LV) dysfunction after cardiac surgery using cardiopulmonary bypass.

Design: Observational study.

Setting: Teaching hospital.

Impact of the Bird-Beak Configuration on Postoperative Outcome After Thoracic Endovascular Aortic Repair: A Meta-analysis.

To investigate the association between the bird-beak configuration (BBC), a wedge-shaped gap between the undersurface of a thoracic endograft and the lesser curvature of the arch after thoracic endovascular aortic repair (TEVAR), and postoperative outcome after TEVAR. The study was performed according to the PRISMA guidelines. The PubMed, EMBASE, and Cochrane databases were searched to identify all case series reporting BBC after TEVAR between 2006 and April 2018.
