Bifurcation lesion

BACKGROUND: Intravascular lithotripsy is effective and safe for managing coronary calcification; however, available devices are limited, and complex lesions have been excluded in previous studies. This study aimed to investigate the effectiveness and safety of a novel intravascular lithotripsy system for severe calcification in a population with complex lesions. METHODS: CALCI-CRACK (ChiCTR2100052058) is a prospective, single-arm, multicenter study. The primary endpoint was the procedural success rate...

BACKGROUND: This study aimed to evaluate the long-term outcomes of double kissing crush stenting (DKC) and mini-culotte technique (MCT) in patients with complex bifurcation lesions. METHODS: This retrospective study enrolled 236 patients who underwent percutaneous coronary intervention (PCI) for complex coronary bifurcation disease between January 2014 and November 2022. The primary endpoint was target lesion failure (TLF), defined as the combination of cardiac death, myocardial infarction (MI), or clinically driven target lesion revascularization (TLR)...

OBJECTIVE: This study aimed to compare the clinical outcomes of double kissing mini-culotte (DKMC) stenting with those of mini-culotte (MC) stenting in treating patients with true coronary bifurcation lesions (CBLs) in the clinical real world. METHODS: This retrospective observational cohort study included 180 consecutive patients with true CBLs (Medina type 1,1,1; 1,0,1; 0,1,1). All eligible patients underwent coronary angiography and percutaneous coronary intervention with two-stent techniques in our hospital; among them, 97 received DKMC treatment and 83 MC treatment...

PURPOSE: This cross-sectional cohort-comparison observational study investigated the value of high-frame-rate vector flow (V Flow) imaging for evaluating differences in carotid plaque shape and biomechanical parameters in patients with mild stenosis according to a recent history of ipsilateral ischemic stroke. METHODS: The present study included 352 patients from February 2023 to October 2023, who were categorized as symptomatic or asymptomatic based on a history of recent ischemic stroke and ipsilateral ischemic lesions detected on head computed tomography or magnetic resonance imaging...

The cognitive impairment will gradually appear over time in Parkinson's patients, which is closely related to the basal ganglia-cortex network. This network contains two parallel circuits mediated by putamen and caudate nucleus, respectively. Based on the biophysical mean-field model, we construct a dynamic computational model of the parallel circuit in the basal ganglia-cortex network associated with Parkinson's disease dementia. The simulated results show that the decrease of power ratio in the prefrontal cortex is mainly caused by dopamine depletion in the caudate nucleus and is less related to that in the putamen, which indicates Parkinson's disease dementia may be caused by a lesion of the caudate nucleus rather than putamen...

BACKGROUND: The number of octogenarians referred to percutaneous coronary interventions (PCI) is rising steadily. The prevalence and prognostic impact of complex PCI (CPCI) in this vulnerable population has not been fully evaluated. METHODS: Patients ≥80 years old who underwent PCI between 2012 and 2019 at Mount Sinai Hospital were included. Patients were categorized based on PCI complexity, defined as the presence of at least one of the following criteria: use of atherectomy, total stent length ≥60 mm, ≥3 stents implanted, bifurcation treated with at least 2 stents, PCI involving ≥3 vessels, ≥3 lesions, left main, saphenous vein graft or chronic total occlusion...

BACKGROUND: Hepatic artery infusion pump (HAIP) with floxuridine/dexamethasone and systemic chemotherapy is an established treatment regimen, which had been reported about converting 47% of patients with stage 4 colorectal liver metastasis from unresectable to resectable.1,2 To this effect, HAIP chemotherapy contributes to prolonged survival of many patients, which otherwise may not have other treatment options. Biliary sclerosis, however, is a known complication of the HAIP treatment, which occurs in approximately 5...

Background : This study examines the impact of the use of the combination of BeGraft and Solaris stent grafts on the outcomes during the covered endovascular reconstruction of aortic bifurcation (BS-CERAB) technique and extension to the iliac arteries. Methods : Consecutive patients with aortoiliac occlusive disease who underwent endovascular treatment using BS-CERAB between January 2020 and December 2023 were included. Patient demographics, symptoms, lesion characteristics, and procedural and follow-up details were collected and analyzed...

The advent of excimer laser coronary atherectomy (ELCA) nearly four decades ago heralded a novel way to treat complex lesions, both coronary and peripheral, which were previously untraversable and thus untreatable. These complex lesions include heavily calcified lesions, ostial lesions, bifurcation lesions, chronic total occlusions, in-stent restenosis (including stent underexpansion), and degenerative saphenous vein grafts. We discuss the technology of ELCA, its indications, applications, and complications, and suggest the "MAXCon ELCA" technique for better outcomes without increased risk...

Cryptococcus is a yeast-like fungus. Pulmonary lesions caused by Cryptococcus neoformans typically present as single or multiple nodules or infiltrative lesions in the lungs; however, endobronchial lesions are rare. A 40-year-old previously healthy Japanese man was referred to our hospital due to an abnormality detected on chest computed tomography. The analysis revealed focal bronchiectasis and bronchial wall thickening in the right upper lobe, which persisted for 6 months. Bronchoscopy showed reddish and edematous mucosa, stenosed bronchi (right B1 and B3), and white moss at the bifurcation of the right upper bronchus...

BACKGROUND: Coronary artery disease is a prevalent global cardiovascular ailment, with percutaneous coronary intervention (PCI) standing out as a crucial method for relieving symptoms and enhancing the quality of life in patients with coronary heart disease. However, the presence of concurrent chronic total occlusion (CTO) and bifurcation lesions within coronary arteries elevates the complexity and treatment risks, especially when the entry point of the CTO is ambiguous. OBJECTIVE: This study aims to present an innovative approach for treating CTO complicated with bifurcation lesions, focusing on true cavity pathfinding assisted by a balloon...

BACKGROUND: Coronary bifurcation lesions are associated with less favourable outcome as compared to other lesion subsets. The role of drug-coated balloons (DCB) for bifurcation lesions has been only investigated in small studies so far, which reported encouraging results. We here describe the results of EASTBOURNE-BIF prospective registry, in which a sirolimus-DCB was used for the treatment of bifurcation lesions. METHODS: Overall, 194 patients with bifurcations lesions identified in the EASTBOURNE study (Medina 1...

BACKGROUND: Intravascular lithotripsy has proven to be safe, less invasive, and effective for coronary and peripheral arteries, and the indication has been extended to the aortic district but there is still little evidence in the literature as only a few cases have been described so far. METHOD: We report a case of intravascular lithotripsy of the infrarenal aorta due to coral reef, chronic occlusion using a single Shockwave M5 + balloon, followed by a covered stent deployment...

PURPOSE: The evidence regarding the treatment of open retrograde stenting of innominate artery (IA) or common carotid artery stenosis (CCA) is limited, and is suspected to carry a high risk of stroke and death. Therefore, the objective of this study was to evaluate the outcomes of such hybrid procedures. METHODS: A retrospective, monocentric study of all patients who underwent retrograde stenting of proximal IA and CCA stenosis via surgical cutdown of the CCA, with or without concomitant CEA, between 2016 and 2023 was performed...

OBJECTIVE: Despite the development of dedicated, two-stent strategies, including the double kissing (DK) crush technique, the ideal technique for coronary artery bifurcation stenting has not been identified. We aimed to compare and determine the absolute risk difference (ARD) of the DK crush technique alone versus provisional stenting approaches for coronary bifurcation lesions, using the Bayesian technique. METHOD: We queried PubMed/MEDLINE to identify randomized controlled trials (RCTs) that compared DK crush technique with provisional stenting for bifurcation lesions, published till January 2023...

OBJECTIVE: The aim of this multicenter national study was to compare the outcomes of primary open surgery (OS) by aortobifemoral bypass (ABFB) with those performed after a failed endovascular treatment (EVT) by Kissing Stent (KS) technique for complex aortoiliac occlusive disease (AIOD) lesions (TASC II C and D). METHODS: All consecutive ABFB cases carried out at twelve vascular surgery centers between 2016 and 2021 were retrospectively collected and analyzed. Data included patients' baseline demographics and clinical characteristics, procedural details, peri-operative outcomes, and follow-up results (survival, patency, amputation)...

BACKGROUND: Percutaneous coronary intervention (PCI) for bifurcation lesions still represents a clinical challenge. The Bioss Lim C is a dedicated device for bifurcation lesions, features a tapered shape and large cells, and thus appears as a promising adjunct to the current interventional cardiologists' armamentarium. We aimed at conducting a prospective multicenter study focusing on early and long-term results after Bioss Lim C implantation for true coronary bifurcation lesions. METHODS: Patients with true bifurcation lesions in whom Bioss Lim C implantation was attempted were enrolled in four Italian centers...

BACKGROUND: Drug eluting balloons (DEB) are a feasible method of rapid delivery of drug to a coronary vessel wall. Their efficacy has been established for the treatment of in-stent restenosis and small vessel disease but there is limited data for their use in bifurcation lesions. OBJECTIVE: The aim of this study was to assess the effectiveness of provisional upfront side-branch DEB use in bifurcation lesions compared to a simple balloon (POBA) or upfront 2 stent bifurcation strategy...
