BACKGROUND: Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic vascular disease. However, there are limited data regarding the impact of Lp(a) levels on the incidence and severity of endothelium-dependent coronary vasomotor response. PATIENTS AND METHODS: A total of 2416 patients without significant coronary artery lesion (<50% stenosis) by coronary angiography and underwent acetylcholine (ACh) provocation test were enrolled and categorized according to their serum Lp(a) level into four quartile groups: less than 6...

Transradial access for cardiac catheterization and percutaneous coronary intervention is recommended by international guidelines to reduce vascular complications. Unfortunately, some factors such as female sex, shorter body surface area and older age, were found to be independent predictors of transradial cardiac catheterization failure. The balloon-assisted tracking technique is a smart trick to avoid crossover from radial to femoral access in case of spasm, tortuosity, or stenosis.

Transcatheter aortic valve replacement is now the standard of care for severe symptomatic aortic stenosis patients who are at high-surgical risk. Percutaneous approach without a surgical cut down has been increasingly adapted by some centers in USA. Percutaneous approach seems to be associated with shorter hospital stay, similar short and late vascular complications, less disabling stroke, similar mortality as well as significantly less hospital cost. However, this technique also requires operators to be able to manage any vascular complications using advanced endovascular interventions to achieve complete hemostasis...

INTRODUCTION: Malnutrition is a well-recognized risk factor for all-cause mortality in hemodialysis patients. However, its role for arteriovenous fistulas outcome has not been exhaustively investigated. Our aim was to point out the impact of Subjective Global Assessment-Dialysis Malnutrition Score as independent predictor of arteriovenous fistulas thrombosis (vascular access thrombosis) and/or significant stenosis (vascular access stenosis). In addition, we compared it with the widespread Charlson Comorbidity Index...

Transfemoral transcatheter aortic valve implantation is an established therapy to treat elderly patients affected by severe aortic stenosis, who are considered to be at high or extreme risk for surgical aortic valve replacement. The transfemoral approach is contraindicated in patients with severe peripheral artery disease, small vessel size or severe tortuosity. In these patients, other vascular access routes such as transapical, subclavian or direct-aortic access may be considered. We describe the first case of a Medtronic Evolut R (Medtronic, Minneapolis, MN, USA) implantation made through the brachial artery in a 75-year-old patient affected by severe aortic stenosis...

Cardiac rhythm disorder is frequently encountered in hemodialysis patients and is often treated with a cardiovascular implantable electronic device (CIED). The conventional CIED requires placement of transvenous leads resulting in subclinical central venous stenosis, which can adversely affect the successful creation of a permanent dialysis vascular access. The technological advancement of a leadless pacemaker provides an opportunity to implement a strategy to preserve central veins in patients with chronic kidney disease...

Background: The ankle-brachial index (ABI) and pulse wave velocity (PWV) are indices of atherosclerosis and arterial stiffness. The Japan-made measuring devices of those indices have spread widely because of their convenience and the significance of the parameters. However, studies that comprehensively discuss the various pitfalls in using these indices are not available. Methods: This study presents several representative pitfalls in using the ABI and brachial-ankle PWV (baPWV) by showing the result sheets of the device, "the Vascular Profiler"...

INTRODUCTION: Stenosis of an arteriovenous fistula or arteriovenous graft for dialysis is a common problem. Stenosis may lead to a number of problems including failure of the fistula. Treatment of stenosis is commonly with percutaneous angioplasty or surgical patch angioplasty with autologous vein or synthetic graft or patch. Here we report the use of bovine pericardial patch angioplasty as an alternative mode of patch angioplasty when percutaneous intervention has failed. METHODS: Patients with fistulae treated with bovine patch angioplasty between 2013 and 2016 were identified from a prospectively maintained renal access database (Cyberren® )...

The maintenance of vascular access patency for end-stage renal disease patients on hemodialysis is necessary for survival. Many nephrologists, nurse practitioners, and nurses have limited experience with the physical examination of the arteriovenous fistula. In this review, we define key terms used in the assessment of an arteriovenous fistula. We discuss the arteriovenous fistula physical exam, including details of inspection, palpation, and auscultation. Using these concepts, we review the abnormal findings that can assist practitioners in determining the location of a stenosis...

BACKGROUND: Hemodialysis graft outflow stenosis is a significant complication occurring in hemodialysis patients with prosthetic grafts for vascular access. Balloon angioplasty remains the first-line endovascular treatment of this complication, although covered stent graft implantation after balloon angioplasty also appears to be an effective and promising treatment. The aim of this study was to evaluate the efficacy and durability of stent graft placement after balloon angioplasty in comparison to balloon angioplasty alone for the treatment of graft outflow stenosis in hemodialysis patients...

OBJECTIVES: To evaluate the feasibility of fully percutaneous closure using a novel collagen-based vascular closure device after transfemoral aortic valve replacement (TAVR). BACKGROUND: TAVR is utilized increasingly for the treatment of severe symptomatic aortic stenosis. Vascular complications related to access and closure dominate the adverse event profile of the procedure despite progressively reducing arteriotomy caliber. The advent of a novel collagen-based device (MANTATM ) and preliminary data suggest this could be used as a routine percutaneous closure device...

INTRODUCTION: Arteriovenous fistulae remain the gold standard of vascular access in haemodialysis. There is currently no consensus on standardised methods of monitoring arteriovenous fistulae. Assessment techniques and practice remain widely variable. The purpose of this study is to determine whether existing evidence supports physical assessment as an effective tool and a good predictor of arteriovenous fistulae dysfunction to allow for timely intervention and improve outcomes. METHODS: A literature search was performed using CINAHL, PubMed, Medline and BNI databases and relevant search terms...

For arrhythmia treatment or sudden cardiac death prevention in hemodialysis patients, there is a frequent need for placement of a cardiac implantable electronic device (pacemaker, implantable cardioverter defibrillator, or cardiac resynchronization device). Leads from a cardiac implantable electronic device can cause central vein stenosis and carry the risk of tricuspid regurgitation or contribute to infective endocarditis. In patients with end-stage kidney disease requiring vascular access and cardiac implantable electronic device, the best strategy is to create an arteriovenous fistula on the contralateral upper limb for a cardiac implantable electronic device and avoidance of central vein catheter...
