BACKGROUND: In-stent restenosis (ISR) has become a significant obstacle to interventional therapy for atherosclerotic cardiovascular disease. The optimal percutaneous coronary intervention (PCI) strategy for patients with coronary ISR remains controversial. This network meta-analysis (NMA) was aimed to compare and estimate the effectiveness of different PCI strategies and commercial devices for the treatment of patients with coronary ISR. METHODS: In present study, we systematically searched PubMed, Embase, Web of Science, and Cochrane Library from database inception to October 20, 2022, to identify randomized controlled trials...

A 37-year-old man with a history of Kawasaki disease presented with total occlusion of the right coronary artery. The patient underwent percutaneous coronary intervention (PCI) with excimer laser coronary angioplasty (ELCA) and plain balloon angioplasty (POBA). Three months after PCI, a coronary aneurysm with restenosis was detected at the PCI site, and PCI was performed again using a small balloon. The aneurysm healed three months after the second PCI procedure. This is the first report describing the long-term outcome after an aneurysm caused by PCI with ELCA and POBA...

BACKGROUND: Balloon non-crossable stenoses represent a challenging subset of coronary artery disease (CAD). They are clinically associated with patients who are older, frailer, and with multi-morbidities, and angiographically with increased tortuosity and coronary artery calcification. Combined rotational (RA) excimer laser coronary atherectomy (ELCA), or RASER, may facilitate stent delivery and deployment in non-crossable, non-dilatable severely calcified lesions. In this study, we assessed preliminary safety and efficacy of the RASER hybrid technique...

Vascular diseases, such as venous insufficiency and coronary artery diseases, have been threatening the health of people. Efficient treatment with proper postoperative care is required to relieve the pain of the patients. Traditionally, venous insufficiency is treated with ligation and stripping, an open surgery whose complication rate cannot be ignored. Coronary artery disease is often treated with balloon angioplasty during which undilatable lesions may be encountered, limiting the efficacy of this approach...

BACKGROUND: Neoatherosclerosis, a prominent contributor to in-stent restenosis (ISR), persists as a formidable challenge during percutaneous coronary intervention. Excimer laser coronary atherectomy (ELCA) and embolic protection devices may help reduce coronary flow disturbance from procedure-related distal embolization. CASE SUMMARY: A 71-year-old man experienced in-stent neoatherosclerosis rupture-related non-ST segment elevation myocardial infarction. Multidisciplinary intracoronary imaging, including intravascular ultrasound and optical coherence tomography (OCT), suggested that the ISR was caused by a neoatherosclerosis rupture that can potentially lead to distal embolization...

BACKGROUND: Managing high thrombotic burden in the context of myocardial infarction remains a challenging scenario. CASE SUMMARY: A 51-year-old male was admitted for a subacute inferior myocardial infarction with persistent chest pain. Emergent coronary angiography showed an ostial-proximal thrombotic occlusion of a large ectatic right coronary artery. Several balloon inflations were performed that were not able to improve distal TIMI flow beyond II. With the intent of vaporizing the remaining thrombus, Excimer Laser Coronary Angioplasty was performed with a favourable outcome...

INTRODUCTION: Complex, coronary stenosis remains a technical challenge that may be responsible for in-stent restenosis and vessel thrombosis. Here we investigated the efficacy and safety of excimer laser coronary atherectomy (ELCA) with contrast mix injection for improving vessel wall stent apposition in undilatable, mostly calcified lesions. AIM: To assess ELCA with contrast mix injection in complex, stented, calcified coronary lesions. MATERIAL AND METHODS: This prospective single-center observational study enrolled 52 consecutive patients (73 lesions), with suboptimal stents implanted in de novo lesions and lesions requiring in-stent restenosis (ISR) due to stent underexpansion using all available means to achieve an optimal result...

Excimer laser coronary angioplasty (ELCA) vaporizes plaques and thrombi, provides better microcirculation, and reduces peripheral embolism when treating acute coronary syndrome. Studies on the efficacy of ELCA for long onset-to-balloon time ST-segment elevation myocardial infarction (STEMI) are limited. Thus, we aimed to examine the efficacy of ELCA for STEMI using the onset-to-balloon time (OBT). A total of 319 patients with STEMI who underwent percutaneous coronary intervention from 2009 to 2012 and from 2015 to 2019 were enrolled...

Objective . Atherosclerosis is the buildup of fats, cholesterol, and other substances on the inner walls of arteries. It can affect arteries of heart, brain, arms, legs, pelvis and kidney, resulting in ischemic heart disease, carotid artery disease, peripheral artery disease and chronic kidney disease. Laser-based treatment techniques like laser atherectomy can be used to treat many common atherosclerostic diseases. However, the use of laser-based treatment remains limited due to the high risk of complications and low efficiency in removing atherosclerostic plaques as compared with other treatment methods...

BACKGROUND: Excimer laser is used to treat coronary artery disease, especially in case of lesions with thrombus and in-stent restenosis (ISR). However, there are no in vivo preclinical studies that have evaluated the pathological reactions of the vessel wall after excimer laser ablation. METHODS: Bare-metal stents were placed in the external iliac arteries of six healthy rabbits. Twenty-eight days later, excimer laser ablation was performed with low-power (45 (fluency)/25 (rate)) in one side, and high-power (60/40) in the opposite side, followed by optical coherence tomography (OCT) evaluation...

In primary percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS), the presence of a thrombus or unstable plaque can cause microvascular obstructions, which may increase infarct size and reduce survival. Excimer laser coronary angioplasty (ELCA) is a unique revascularization technique that can vaporize plaques and thrombi. However, to date, only few reports indicate the efficacy of ELCA for ACS. We retrospectively analyzed 113 consecutive ACS patients who underwent PCI with either ELCA or manual thrombus aspiration therapy (TA) before balloon angioplasty or stenting and who had a Thrombolysis in Myocardial Infarction flow (TIMI) grade 0 on the first contrast injection within 24 h of onset at our hospital from March 2011 to March 2020...

Moderate-severe calcification increases procedural complications and impairs long-term prognosis post-PCI. Intravascular imaging (particularly optical coherence tomography [OCT]) is useful in guiding the treatment of calcified lesions. Weighted sum of calcium length, arc, and thickness on OCT can predict adequate stent expansion, identifying when atherectomy is required. With intravascular imaging guidance, various techniques alone or in combination may be used in an algorithmic fashion to modify calcified lesions...

Excimer Laser Coronary Atherectomy (ELCA) is a well-established therapy that emerged for the treatment of peripheral vascular atherosclerosis in the late 1980s, at a time when catheters and materials were rudimentary and associated with the most serious complications. Refinements in catheter technology and the introduction of improved laser techniques have led to their effective use for the treatment of a wide spectrum of complex coronary lesions, such as thrombotic lesions, severe calcific lesions, non-crossable or non-expandable lesions, chronic occlusions, and stent under-expansion...
