OBJECTIVE: With the introduction of the latest generation Sapien 3 transcatheter aortic valve, there has been a reduction in the usage of transapical (TA) approach for TAVRs in many centers. However, despite the smaller sheath size and more stream-lined delivery system, vascular complications continue to occur, especially in patients with peripheral vascular disease. Thus, our institution has maintained a stringent TA protocol aiming to prevent these complications. We hypothesize that this protocol has helped to reduce vascular complications and improve outcomes at our institution even in the Sapien 3 era...

Major vascular complications still occur in ~4.2% of transcatheter aortic valve replacement (TAVR) procedures. These complications are a major safety drawback of TAVR when compared to surgical aortic valve replacement (SAVR). Contemporary strategies designed to minimize and effectively treat vascular complications are of immense importance to a successful TAVR program. This review discusses strategies to optimize TAVR access and device choice along with TAVR access complication management. Iliac complications are less frequently encountered and can be managed effectively via the TAVR sheath over the TAVR wire employing ipsilateral proximal iliac balloon occlusion and endovascular repair...

OBJECTIVES: Using the British Cardiovascular Intervention Society percutaneous coronary intervention (PCI) database, access site choice and outcomes of patients undergoing PCI with previous coronary artery bypass grafting (CABG) were studied. BACKGROUND: Given the influence of access site on outcomes, use of radial access in PCI-CABG warrants further investigation. METHODS: Data were analyzed from 58,870 PCI-CABG procedures performed between 2005 and 2014...

Fusarium wilt caused by Fusarium oxysporum f. sp. pisi ( Fop ) is one of the most destructive diseases of pea worldwide. Control of this disease is difficult and it is mainly based on the use of resistant cultivars. While monogenic resistance has been successfully used in the field, it is at risk of breakdown by the constant evolution of the pathogen. New sources of quantitative resistance have been recently identified from a wild relative Pisum spp. collection. Here, we characterize histologically the resistance mechanisms occurring in these sources of quantitative resistance...

Transcatheter aortic valve implantation was performed on a 78-year-old patient. Elective circulatory support with cardiopulmonary bypass was planned because of left ventricular function impairment and hemodynamic instability. Limited vascular access was due to a severe atherosclerotic aorta distal to the origin of the left carotid artery. The right arm was the only safe vascular access site. However, at least 2 vascular access sites for angiographic catheter and inflow of circulatory support were required. An arterial inflow line equipped with a side arm was developed to enable single access to the right axillary artery to be used for the above purposes...

BACKGROUND: The carotid artery is a novel access route for transcatheter aortic valve implantation (TAVI), especially useful in patients unsuitable for traditional access routes including transfemoral (TF), subclavian, transapical (TAp), and aortic (TAo). This systematic review summarizes the evidence on TAVI via the carotid artery for its efficacy and safety. METHODS: A systematic review was conducted as per the Preferred Reporting Instructions for Systematic Reviews and Meta-analysis (PRISMA) guidelines on three online databases: Medline (via Pubmed), SCOPUS, and Cochrane Database...

We provide strong evidence of the effectiveness of homogenously self-propelled particle-in-particle diffusion, interaction and growth protocol. This technique was used for one-pot synthesis of novel nitrogen-graphene oxide (N-GO)/Co3 O4 nanocrystals with cuboid rectangular prism-shaped nanorods (NRs) along {110}-plane and truncated polyhedrons with densely-exposed, multi-facet sites along {311} and {111} planes. These hierarchal nanocrystals create electrode catalyst patterns with vast-range accessibility to active Co2+ sites, a vascular system for the transport and retention of captured O2 molecule interiorly, and low adsorption energy and dense electron configuration surfaces during the oxygen reduction reaction (ORR)...

INTRODUCTION: Current guidelines recommend preoperative antibiotics in all vascular surgery cases. However, we hypothesize that patients undergoing arteriovenous fistula (AVF) and arteriovenous graft (AVG) creation have low rates of postoperative surgical site infection (SSI) and that preoperative antibiotic prophylaxis in these patients may not be necessary. METHODS: This is a retrospective review of all patients who underwent AVF and AVG creation from November 2014 through July of 2016 at a single institution...

BACKGROUND: Duplex ultrasound (DUS) mapping of the veins and arteries of the upper extremity is a well-established practice in arteriovenous fistula creation for long-term hemodialysis access. Previous publications have shown that vein diameters varying from 2 to 3 mm are predictive of success. Regional anesthesia is known to result in vasodilation and thus to increase the diameter of upper extremity veins. This study compares the sizes of veins measured by preoperative DUS mapping with those obtained after regional anesthesia to determine whether intraoperative DUS results in increased vein diameters and thus changes in the operative plan...

BACKGROUND: Wound healing is a complex process that relies on growth factors and stimulation of angiogenesis. Tissue engineering materials composed of adipose-derived stem cells (ADSCs) and silk fibroin (SF)/chitosan (CS) may be able to solve this problem. The aim of this study was to investigate the wound-healing potential of ADSC-seeded SF/CS in streptozotocin-induced diabetic rats. MATERIALS AND METHODS: Thirty-six male Sprague-Dawley rats were purchased and randomly assigned into 3 groups: a control group (no graft), a group treated with SF/CS film graft, and a group treated with ADSC-seeded SF/CS graft...

BACKGROUND: The external iliac vein is the standard site used for venous anastomosis in kidney transplantation. When a pre-transplantation diagnosis of iliocaval thrombosis is established, a different and suitable venous drainage for the renal outflow must be identified for successful transplant. METHODS: We report 4 cases of kidney transplantation, performed from 2004 to 2016, in recipients presenting with thrombosis of the inferior vena cava and iliac system needing, because of the lack of access for dialysis, urgent kidney transplantations...

Trans-carotid access for trans-catheter aortic valve replacement is a valid alternative in patients with aortic valve dysfunction, severe peripheral vascular disease, and high-risk for surgery. However, in the event of the need for a bailout valve-in-valve procedure, the safety of this access site is uncertain. We report a patient with aortic regurgitation, previous coronary surgery, peripheral vascular disease, and impaired ventricular function who underwent a CoreValve Evolut-R (Medtronic Inc, Minneapolis, MN) implantation through the left carotid artery followed by a successful valve-in-valve procedure with a 26-mm Edwards Sapien3 valve (Edwards Lifesciences, Irvine, CA) through the same carotid access site...

OBJECTIVES: The objective was to assess the effect of ultrasound (US)-guidance compared to the anatomical landmark (AL) approach in patients requiring femoral artery (FA) access for coronary angiography/percutaneous coronary interventions (PCI). BACKGROUND: US-guidance has been proposed as a strategy to optimize FA access, potentially leading to decreased vascular complications. METHODS: Patients requiring FA access for coronary angiography/PCI were randomized to the US-guided or AL approaches...

The left ventricular apex has excellent accessibility to the aortic valve, mitral valve, left ventricular outflow tract and thoracic aorta. Although the number of transapical approach in transcatheter aortic valve replacement has been decreasing in recent years, it is still a useful option for patients with very poor peripheral vascular access. The apex has been chosen as a primary access site for many devices of transcatheter mitral valve repair/replacement and mitral valve-in-valve procedures. Additionally, the transapical approach has been used for other transcatheter cardiovascular interventions such as paravalvular leak repair after mitral or aortic valve replacement, pseudoaneurysm repair of the left ventricular outflow tract, and thoracic endovascular aortic repair...

AIMS AND BACKGROUND: Although guideline recommendations have shifted towards a transradial route, femoral puncture is still an established vascular access, especially for complex coronary interventions. The FemoSeal™ vascular closure device (FVCD) helps to reduce femoral compression time and access site complications after removal of the catheter sheath. To ensure safe use, an angiography of the femoral artery prior to FVCD deployment is recommended by the manufacturer. We postulate that omitting this angiography does not relevantly increase the risk for vascular complications...

OBJECTIVES: This study was designed to examine the association between adopting the transradial approach for percutaneous coronary intervention (PCI) and rates of vascular complications following transfemoral PCI. BACKGROUND: Recent studies raised concerns that operators adopting the transradial approach may lose their transfemoral access skills and experience increased rates of vascular complications. METHODS: Retrospective analysis of data from the NCDR CathPCI Registry to examine the rates of vascular complications among physicians who were femoral operators (>90% of cases) in 2010-2011 and later adopted the transradial approach to PCI among low-, intermediate-, or high-level adopters (≤33%, 34-66%, and >66%, respectively) in 2014-2015...

Introduction: The "transfemoral (TF) first" approach to access route selection in transcatheter aortic valve implantation (TAVI) is popular; however, the risk of major vascular complications is substantial. The "best for TF" approach identifies only the patients with ideal anatomy for TF-TAVI, potentially minimizing complications. Aim: To characterize the outcomes of patients undergoing TAVI at a large-volume site that employs this approach. Material and methods: Patients who underwent TAVI at the Bad Rothenfelde Heart Centre between 2008 and 2016 were consecutively enrolled...
