OBJECTIVES: To evaluate the outcomes of rotational atherectomy for heavily-calcified side branches of coronary bifurcation lesions. BACKGROUND: Side-branch (SB) preservation is clinically important but technically challenging in heavily-calcified non-left main true bifurcation lesions. SB rotational atherectomy (SB RA) is sometimes mandatory but the clinical outcomes are not well studied. METHODS: We retrospectively studied the outcomes of patients who underwent RA at our institute for heavily calcified, balloon-uncrossable or-undilatable SB lesions over an approximately 5-year period (January 2011 to September 2016)...

Coronary stent implantation has significantly improved percutaneous coronary intervention and enabled the management of early complications of plain balloon angioplasty. However, a new complication has accompanied these improvements: in-stent restenosis (ISR) arising from neointimal hyperplasia. ISR after coronary angioplasty is currently one of the main limitations of this method, leading to the recurrence of exertional angina pectoris or acute coronary syndromes. The clinical incidence of ISR after bare-metal stent (BMS) implantation is approximately 20%-35%...

Critical limb ischemia (CLI) is a terminal stage of peripheral arterial disease that, in the absence of intervention, may lead to lower extremity amputation or death. Endovascular interventions have become a first-line approach to the management of CLI and have advanced considerably within the past decade. This review summarizes the types of percutaneous devices and the techniques that are available for the management of CLI and the data supporting their use. These include devices that establish and maintain vessel patency, including percutaneous transluminal angioplasty, drug-coated balloons, bare metal stents, drug-eluting stents, bioresorbable vascular scaffolds, and atherectomy; devices that provide protection from embolization; and, cell-based therapies...

BACKGROUND: Intracranial atherosclerotic disease is a well-known cause of ischemic stroke. Following the SAMMPRIS trial, medical treatment is favored over stenting. Drug-eluting balloons (DEB) are widely used in coronary angioplasty, showing better results than bare-surface balloons. There is little evidence of DEB employment in intracranial stenosis, especially of paclitaxel-eluted balloons (pDEB). The Neuro Elutax SV (Aachen Resonance) is the first CE certificated pDEB for intracranial use...

Background: The drug-eluting stent is a standard approach for the treatment of coronary artery disease. Propylthiouracil (PTU), an antithyroid drug, has been proven to suppress neointimal formation after balloon injury. Materials and methods: This study used a biodegradable polymer coating with PTU to test its effects on platelet function, re-endothelialization, and neointimal formation after vascular injury. Electrospinning was used to fabricate hybrid stents and generate PTU-loaded nanofibers...

We evaluated our quarter-century experience with percutaneous coronary intervention (PCI) in patients with cardiac allograft vasculopathy (CAV). CAV is a progressive form of atherosclerosis that is characterized by diffuse intimal thickening. It is a major cause of morbidity and mortality after orthotopic heart transplantation (OHT). Effective treatment options are limited. PCI has been used as a palliative treatment in selected patients. We retrospectively analyzed 140 patients with CAV who underwent PCI from 1992 to 2017 at the University of California, Los Angeles (UCLA) Medical Center...

Final stent dimensions remain an important predictor of restenosis, target vessel revascularisation (TVR) and subacute stent thrombosis (ST), even in the drug-eluting stent (DES) era. Stent balloons are usually semi-compliant and thus even high-pressure inflation may not achieve uniform or optimal stent expansion. Post-dilatation with non-compliant (NC) balloons after stent deployment has been shown to enhance stent expansion and could reduce TVR and ST. Based on supporting evidence and in the absence of large prospective randomised outcome-based trials, post-dilatation with an NC balloon to achieve optimal stent expansion and maximal luminal area is a logical technical recommendation, particularly in complex lesion subsets...

Biodegradable vascular scaffolds (BVS) are novel treatments for obstructive atherosclerotic cardiovascular disease that have been developed to overcome the limitations of traditional metallic drug-eluting stents (DES). The mechanical properties of bioabsorbable polymers used for the production of novel BVS are a key consideration for the clinical translation of this emerging technology. Herein, we describe the engineering of an in situ light-activated vascular scaffold (ILVS) comprised of a biodegradable citric acid-based elastomeric polymer, referred to as methacrylated poly-diol citrate (mPDC), and a diazeniumdiolate chitosan nitric oxide donor (chitoNO)...

INTRODUCTION: Recurrent central venous restenosis is problematic in patients with ipsilateral arteriovenous fistula. We report our experience using a drug-eluting stent for the treatment of recurrent central vein restenosis. CASE REPORT: A 60-year-old man consulted our hospital because of recurrent swelling of his left upper limb with radial-cephalic arteriovenous fistula that originated in the distal forearm. More than 3 years prior, two bare-metal stents were placed for the obstructed lesions in the left subclavian and brachiocephalic venous lesions, and repeated balloon angioplasty for recurrent in-stent stenosis was performed approximately every 3 months...

The arteriovenous fistula is currently the best permanent access for the hemodialysis patient. Unfortunately, stenosis impairs maturation, long-term survival, and function of the arteriovenous fistula. Angioplasty currently is the best procedure for the treatment of immature and dysfunctional arteriovenous fistulas. In this review, the authors discuss the optimum time to evaluate arteriovenous fistulas for maturity, methods of evaluation for maturity, and the role of angioplasty in salvaging immature arteriovenous fistulas...
