Excimer-laser coronary angioplasty can be used to modify undilatable and uncrossable lesions in native arteries and in-stent restenosis which are increasingly encountered with the ageing population undergoing coronary intervention. We present our laser experience over a 10-year period in a large cardiac tertiary centre. METHOD: Retrospective analysis of prospectively collected data on all procedures where laser was used from August 2008 to December 2019. Clinical presentation, demographics, and procedural details were all recorded...

Background: ST-segment elevation myocardial infarction (STEMI) and peptic ulcer perforation are both medical emergencies that require urgent intervention. In case that these time-sensitive medical emergencies present concomitantly, it remains unclear which one should be treated first. Case summary: An 85-year-old man with melaena, epigastric pain, and severe anaemia was transferred to our emergency department and diagnosed as having inferior STEMI based on electrocardiogram...

Background: Acute coronary syndrome caused by unprotected left main coronary artery (ACS-ULMCA) occlusion has a high mortality due to the formation of plaques and rich thrombi. Although excimer laser coronary angioplasty (ELCA) is effective in debulking and ablation of plaque burden and rich thrombi, its effectiveness in ACS-ULMCA remains unknown. Case summary: We conducted percutaneous coronary intervention (PCI) using ELCA for six patients with ACS-ULMCA from February 2016 to May 2019...

INTRODUCTION: Combining rotational (RA) and excimer laser coronary atherectomy (ELCA)-RASER atherectomy-is technique utilized in the percutaneous management of calcific coronary disease. The evidence base examining its safety and utility is sparse and limited to small case-series. This study examines the patterns and outcomes of RASER atherectomy use in the largest cohort to date. METHODS: Using the British Cardiac Intervention Society database, data were analyzed on all PCI procedures in the UK between 2006 and 2016...

Percutaneous coronary intervention (PCI) is one of the most frequent non-surgical procedures performed worldwide. As any invasive procedure, PCI is accompanied by a low but still important risk of complications. One such very rare complication is when the angioplasty balloon cannot be deflated. We present a case of undeflatable balloon during chronic total occlusion PCI and we report a novel technique for balloon retrieval: using the Excimer light amplification by stimulated emission of radiation (Laser) coronary atherectomy device...

Excimer laser coronary atherectomy (ELCA) during percutaneous coronary intervention (PCI) has been in use for more than twenty years. While early experiences were not favorable over balloon angioplasty alone, with improvement in operator technique, patient selection and technology, ELCA has established its own niche in contemporary PCI as a safe and effective atherectomy strategy. With growing experience in complex coronary interventions worldwide, ELCA has become one of the essential atherectomy tools offering unique advantages over other atherectomy devices...

AIMS: Excimer Laser Coronary Angioplasty with adjunctive contrast (ELCA-con) is described as one potential option to facilitate intra-coronary stent expansion; however, the benefits and risks of this technology remain incompletely understood. We performed a retrospective single center study to evaluate procedural success, risks, and clinical outcomes of ELCA-con assisted percutaneous coronary intervention (PCI) for stent under-expansion. METHODS AND RESULTS: Twenty-six consecutive patients underwent ELCA-con assisted PCI from 2014 to 2019 for stent under-expansion...

This study aimed to evaluate the efficacy and safety of excimer laser coronary atherectomy (ELCA) prior to paclitaxel-coated balloon angioplasty for de novo coronary artery lesions. This retrospective observational study analyzed 118 eligible patients with de novo coronary artery disease whose only percutaneous coronary intervention was a drug-coated balloon angioplasty (i.e., no subsequent stent placement). Data related to our primary outcomes of interest-incidence of major adverse cardiovascular and cerebral events (MACCE), and incidence of procedural complications (bailout stenting and minor complications)-were collected and retrospectively analyzed...

Background: Optimal strategy for treating bifurcation lesions or lesions with large thrombus in left main disease remains elusive. Excimer laser coronary angioplasty (ELCA) is a therapeutic option for thrombotic lesions in acute coronary syndrome. Case summary: A 68-year-old man with chest pain was transferred to our emergency department, and subsequently diagnosed as inferior ST-segment elevation myocardial infarction (STEMI). Emergent coronary angiography revealed a 75% stenosis in the left main trunk (LMT)...

Device uncrossable lesions are a challenge in interventional cardiology and despite improvements in balloon and microcatheter profile, rotational atherectomy is necessary in some circumstances in order to ablate and traverse the lesion. Nevertheless, the application of rotational atherectomy requires utilization of a specific wire, Rotawire, which is not always so easily navigable. Debulking of device uncrossable lesions can be performed by coronary laser over any kind of angioplasty guidewire. We present a series of six patients with chronic total (100%) and functional occlusions (99% stenosis) in whom after successful wire crossing, microcatheter failed to traverse the lesion...

Coronary perforation during excimer laser coronary angioplasty( ELCA) is a rare but life threatening complication. A 55-year-old man was admitted to our hospital for management of acute coronary syndrome. ELCA was attempted for the left anterior descending coronary artery (LAD);however, coronary perforation of LAD occurred during the procedure. The patient was transferred to the operation theater and emergency surgical repair was performed. LAD and the diagonal branch were ligated, an aorto-coronary bypass grafting for the distal LAD and the diagonal branch using the saphenous veins...

This study evaluated the 1-year efficacy of excimer laser coronary angioplasty (ELCA) before drug-coated balloon (DCB) dilatation for the treatment of in-stent restenosis (ISR). Forty consecutive patients with ISR were treated by DCB with or without the use of ELCA (ELCA plus DCB, N = 20; DCB alone, N = 20). Debulking efficiency (DE) value was defined as the neointima area on optical frequency domain imaging (OFDI) debulked by ELCA. The patients in the ELCA plus DCB group were divided into two groups (greater DE (GDE), N = 10; smaller DE (SDE), N = 10) based on the median value of DE...

Excimer laser coronary angioplasty (ELCA) is a unique revascularization modality that can vaporize plaque and thrombus. Compared to thrombus aspiration therapy, ELCA is reported to provide better microcirculation and reduced peripheral embolism in treatment for acute coronary syndrome. Excimer laser catheters come in various sizes, and we sought to compare the 0.9- and 1.4-mm-diameter catheters. We retrospectively enrolled 90 acute myocardial infarction (AMI) patients who underwent primary percutaneous coronary intervention with excimer laser from August 2013 to March 2017 in our hospital...
