Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main source(s): Cardiovascular Imaging Research Group, Medical Centre, Semmelweis University. Introduction The improved spatial resolution photon-counting detector CT (PCD-CT) allows better image quality and less artefacts even in high-density structures, such as coronary artery stents. Purpose Ou...

Background. Deep wall excision during directional atherectomy has been reported in one study to increase the risk of subsequent restenosis. On the other hand, we have observed that the probability of late (6-month) restenosis is reduced by maximizing postprocedure luminal diameter. Although such maximal luminal enlargement by directional atherectomy has not increased procedural complications in...

Objective: This study aims to investigate the changes in soluble cell adhesion molecules in patients with coronary heart disease before and after coronary stent implantation and to investigate the feasibility of SICAM-1 as an indicator to predict the postoperative coronary restenosis severity. Methods: A total of 120 cases of patients with coronary stent implantation were selected as research o...

BACKGROUND AND PURPOSE Carotid endarterectomy (CEA) of stable atherosclerotic plaques is associated with an increased risk for restenosis. Patients with transient ischemic attack and patients with and stroke have relatively unstable atherosclerotic plaques. However, carotid plaques stabilize over time after a cerebrovascular event due to plaque repair after rupture. These findings raised 2 ques...

BACKGROUND Carotid artery stenting (CAS) has been advocated as an alternative to redo surgery for the treatment of post-carotid endarterectomy (CEA) stenosis. This study analyzed the efficacy of CAS for post-CEA restenosis, focusing on an analysis of technical and anatomical predictive factors for in-stent restenosis. METHODS We performed a retrospective monocentric study. We included all pat...

BACKGROUND Angiographic restenosis after percutaneous coronary interventional procedures is more common than recurrent angina. Clinical and angiographic factors associated with asymptomatic versus symptomatic restenosis after percutaneous coronary intervention were compared. METHODS AND RESULTS All patients with angiographic restenosis from the BENESTENT I, BENESTENT II pilot, BENESTENT II, M...

Restenosis remains the main complication of balloon angioplasty and/or stent implantation. Preclinical testing of new pharmacologic agents preventing restenosis largely rely on porcine models, where restenosis is assessed after endothelial abrasion of the arterial wall or stent implantation. We combined endothelial cell denudation and implantation of stents to develop a new clinically relevant ...

BACKGROUND In the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS), early recurrent carotid stenosis was more common in patients assigned to endovascular treatment than it was in patients assigned to endarterectomy (CEA), raising concerns about the long-term effectiveness of endovascular treatment. We aimed to investigate the long-term risks of restenosis in patients includ...

CONTEXT Previous studies have assessed the predictive value of clinical and angiographic parameters for development of restenosis after vascular interventions. The composition of the atherosclerotic plaque at the intervention site has had limited evaluated as a marker for restenosis [corrected]. OBJECTIVE To investigate the relationship between atherosclerotic plaque histology and the occurre...
