OBJECTIVES: We aimed to test a novel stent-less revascularization strategy using a combination of excimer laser coronary angioplasty (ELCA) and drug-coated balloon (DCB) for patients with acute coronary syndrome (ACS). BACKGROUND: Percutaneous coronary intervention with drug eluting stents is a standard invasive treatment for ACS. Some unsolved issues however remain, such as stent thrombosis and bleeding risks associated with dual antiplatelet therapy. METHODS: Consecutive ACS patients were planned to receive either a DCB application following ELCA without a stent implantation or conventional revascularization with a coronary stent...

Excimer laser coronary atherectomy (ELCA) has been used for the treatment of complex percutaneous coronary intervention (PCI) such as in-stent restenosis (ISR). However, little information was provided about the clinical outcomes after treatment with ELCA for ISR of drug-eluting stents (DES). This study aimed to investigate the long-term clinical outcomes after PCI with ELCA for ISR of DES.A total of 81 consecutive patients with 87 lesions who underwent PCI for ISR of DES were included. Patients were classified into a PCI with ELCA group (23 patients with 24 lesions) and a PCI without ELCA group (58 patients with 63 lesions)...

RATIONALE: Thin-cap fibroatheroma (TCFA) and red thrombus are suggested as a high-risk of embolic complications during percutaneous coronary intervention (PCI). Intracoronary aspiration procedures occasionally result in either an insufficient thrombus removal or provide no significant effects on TCFA. PATIENT CONCERNS: A 76-year-old male underwent coronary angiography for chest pain. DIAGNOSES: Coronary angiography revealed a tight stenosis at the right coronary artery which resulted in treatment by PCI...

: Excimer coronary laser atherectomy (ECLA) has been shown to be both well tolerated and effective for plaque modification. Its technology is based on ultraviolet energy and is capable of disintegrating atheroma, without burning or grossly fragmenting it. ELCA has proven effective in the percutaneous treatment of a variety of complex lesions. Here we present a case of multiple heavy calcified lesions successfully prepared with ELCA and finally treated with the implantation of multiple bioresorbable scaffolds...

Parastagonospora nodorum is an important pathogen of wheat. The contribution of secondary metabolites to this pathosystem is poorly understood. A biosynthetic gene cluster (SNOG_08608-08616) has been shown to be upregulated during the late stage of P. nodorum wheat leaf infection. The gene cluster shares several homologues with the Cercospora nicotianae CTB gene cluster encoding the biosynthesis of cercosporin. Activation of the gene cluster by overexpression (OE) of the transcription factor gene (SNOG_08609) in P...

Treatment of in-stent restenosis (ISR) is associated with a high incidence of recurrence. This study evaluated the clinical safety and 6-month efficacy of excimer laser coronary angioplasty (ELCA) before scoring balloon dilatation for the treatment of ISR. Twenty-three patients with ISR were included and treatment strategy of ISR was dependent on each operator. Twelve patients among those were treated with ELCA before scoring balloon dilatation (ELCA group) and 11 patients were treated with scoring balloon alone (non-ELCA group)...

BACKGROUND: Excimer laser coronary atherectomy (ELCA) recently became available in Japan, but ELCA's effectiveness and safety are not clear. METHODS AND RESULTS: We enrolled consecutive patients who underwent ELCA and were registered in the Utility of Laser for Transcatheter Atherectomy-Multicenter Analysis around Naniwa (ULTRAMAN) registry comprising six Japanese medical centers around Naniwa in Japan with patients registered from April 2006 to June 2015. We evaluated the catheter sizes used and compared the success rate, thrombolysis in myocardial infarction (TIMI) flow, blush score, and complications between the rich-thrombus (RT) group [acute coronary syndrome (ACS) and saphenous vein graft (SVG)] and the poor-thrombus (PT) group [in-stent restenosis (ISR), chronic total occlusion (CTO), calcification, and long or bifurcation (L&B) lesions]...

Stent underexpansion is a risk factor for in-stent restenosis (ISR) and stent thrombosis. Although excimer laser coronary atherectomy (ELCA) with contrast medium was shown to be effective to improve stent underexpansion in undilatable lesions, precise mechanism of this technique was not well understood. We report a case of ISR with stent underoptimal implantation within a circumferential-calcified atherosclerotic plaque beneath the stent strut that could not be dilated by repeated high-pressure balloon inflations...

AIM: An innovative xenon-chlorine (excimer) pulsed laser catheter (ELCA X80) has been recently used for the treatment of complex coronary lesions, as calcified stenosis, chronic total occlusions and non-compliant plaques. Such complex lesions are difficult to adequately treat with balloon angioplasty and/or intracoronary stenting. The aim of this study was to examine the acute outcome of this approach on a cohort of patients with coronary lesions. METHODS AND RESULTS: Eighty patients with 100 lesions were enrolled through four centers, and excimer laser coronary angioplasty was performed on 96 lesions (96%)...

UNLABELLED: Recently, Social Life Cycle Assessment (S-LCA) has been developed under the methodological framework of Life Cycle Thinking (LCT) to evaluate the social impacts that emerge during the overall life cycle of a product or service. There is not yet a standardized methodology for S-LCA as there is for environmental LCA (eLCA), due to the nature of social impacts that do not depend only on the processes themselves, but also on the behavior and context of actors (manufactures, consumers, local community members, etc...

Stent underexpansion is known as a major cause of restenosis and stent thrombosis in calcified coronary lesions. We report a case of calcified nodule pretreated with excimer laser coronary angioplasty (ELCA) in acute coronary syndrome (ACS). Excimer laser use altered underlying lesion morphology such as calcified nodule and accompanied plaque and thrombus. Pretreatment of ELCA may be a useful tool to get a full expansion of the deployed stent without distal embolism for calcified nodule in ACS.

Excimer laser coronary atherectomy (ELCA) is based on ultraviolet energy and is capable of disintegrating atheroma, without burning or grossly fragmenting it. ELCA has proven effective in the percutaneous treatment of a variety of complex lesions, including chronic total occlusions (CTO) and severely calcified lesions, in case of balloon failure-tocross or failure-to-expand. Here we present a case of a successful CTO recanalization with ELCA after balloon failure, review the literature on this topic, and present an algorithm outlining the management of this challenging clinical scenario...

The pharmaceutical and fine chemical industries are eager to strive toward innovative products and technologies. This study first derives hotspots in resource consumption of 2839 Basic Operations in 40 Active Pharmaceutical Ingredient synthesis steps through Exergetic Life Cycle Assessment (ELCA). Second, since companies are increasingly obliged to quantify the environmental sustainability of their products, two alternative ways of simplifying (E)LCA are discussed. The usage of averaged product group values (R(2) = 3...

We report the successful retrieval of an entrapped interventional guide wire between a newly deployed coronary stent and severely calcified vessel wall. Using a buddy wire technique, the stent was deployed at high pressure in a culprit lesion of the left anterior descending (LAD) artery. The buddy wire in the LAD artery was entrapped between the deployed stent and severely calcified vessel wall, as it was not removed before stent deployment, and could not be retrieved. Neither balloon catheters nor a microcatheter were able to be advanced behind the stent over the entrapped guide wire...

The purpose of the presentation is to highlight innovation in practice with regards how the end of life care for all e-learning programme was implemented and integrated within a hospice. Key concepts include the introduction of e- learning to the clinical staff as a way of learning. How then could this programme be integrated into the working day and how best to monitor the progress of that integration. The issues were around availability of facilities, such as IT equipment. The varying levels of ability of the staff using the computers, and how those who were less confident could be supported...

BACKGROUND/OBJECTIVES: Stent underexpansion is a risk factor for in-stent restenosis and stent thrombosis. Existing techniques to optimize stent expansion are sometimes ineffective. The aim of this study was to evaluate the effectiveness and feasibility of Excimer Laser Coronary Angioplasty (ELCA) in improving stent expansion when high-pressure non-compliant balloon inflation was ineffective. METHODS AND RESULTS: ECLA ablation was performed at high energy during contrast injection and only within the underexpanded stent...

The indications for Excimer laser coronary atherectomy (ELCA) have been refined in modern interventional practice. With the expanding role for optical coherence tomography (OCT) providing high-resolution intra-coronary imaging, this article examines the appearance of the coronary lumen after ELCA. Each indication for ELCA is discussed and illustrated with a clinical case, followed by detailed analysis of the OCT imaging pre and post ELCA. The aim of the article is to provide information to interventional cardiologists to facilitate decision making during PCI, when ELCA has been used as part of the interventional strategy...
