Two peri-stent contrast stainings and one late restenosis in the late phase after sirolimus-eluting stent implantation.

ABSTRACT: Both peri-stent contrast staining (PSS) and late restenosis are abnormal findings after drug-eluting stent implantation and they occur with low incidence. We describe a case with two PSSs and one late restenosis after sirolimus-eluting stent implantation. Persistent high value of C-reactive protein in this patient suggested chronic systematic inflammation as a contributing factor of these abnormal findings. .

A case of in-stent restenosis with pathologically proven chronic inflammation seven years after sirolimus-eluting stent implantation.

Project description:A 67-year-old man was admitted to our hospital due to chest pain at rest. Seven years previously, the patient underwent percutaneous coronary intervention (PCI) of the left ascending artery and implanted sirolimus-eluting stent (SES). Coronary angioscopy (CAS) performed at that time showed a white plaque at the SES site. Two years after the first PCI, repeat CAS demonstrated light yellow plaques at the SES site. At the time of his presentation to our hospital, coronary angiography showed in-stent restenosis at the SES site, and CAS demonstrated the plaque rupture with presence of dense yellow plaque and various thrombi. After distal protection, drug-eluting balloon treatment was performed. Collected specimens from culprit sites included foamy macrophages, cholesterin crystals, neutrophils, and fibrin, suggesting that progressive neoatherosclerosis at the SES site triggered the acute coronary syndrome. This study highlights the importance of ensuring careful patient follow-up after SES implantation. <Learning objective: After 1st generation drug-eluting stent implantation, careful follow up is warranted, as the process of neoatherosclerosis can be ongoing and contribute to in-stent restenosis.>.

Late peri-stent contrast staining appearance due to rupture of atherogenic neointima following drug-eluting stent.

Project description:The development of peri-stent contrast staining (PSS) after coronary intervention with implantation of a stent is observed in approximately 1-3% of patients treated with drug-eluting stent. Although the cumulative incidences of late in-stent restenosis and stent thrombosis are significantly higher in lesions with PSS than in those without the finding, the mechanisms for the development of PSS have not yet been fully elucidated. In this report, we describe a case of rapid development of PSS with ulcer formation caused by rupture of atherogenic neointima, which was observed by serial optical coherence tomography examinations over 6 months. Protrusion of the stent-jailed underlying necrotic core toward the lumen by the contracting force might have resulted in formation of atherogenic neointima within the stent. Subsequently, rupture of this necrotic core induced by iatrogenic neointimal injury due to balloon dilation and dissolution of the accumulated necrotic core may have resulted in PSS formation 6 months after the procedure. These findings may be helpful for consideration of etiology and therapeutic strategy for lesions with PSS. <Learning objective: The mechanisms of peri-stent contrast staining (PSS) formation late after drug-eluting stent (DES) implantation are diverse. Rupture of atherogenic neointima with subsequent dissolution of the stent-jailed underlying plaque debris could be one of the mechanisms of rapid PSS formation after implantation of DES. An accurate assessment of lesion morphology within the stent and patient-tailored management can reduce morbidity and mortality in patients who have undergone DES implantation.>.

Optical coherence tomography images of bell-shaped appearance in late sirolimus-eluting stent restenosis with extension of previous incomplete stent apposition.

Project description:Late adverse events including late stent thrombosis and late catch-up phenomenon after percutaneous coronary intervention have been a serious clinical problem in the drug-eluting stent era. Recently, peri-stent contrast staining, namely extension of incomplete stent apposition was reported following drug-eluting stent implantation. Here, we report a case of late incomplete stent apposition with late stent restenosis 3 years after sirolimus-eluting stent implantation. We evaluated this restenotic site by intravascular ultrasound (IVUS) and optical coherence tomography (OCT). Though IVUS demonstrated irregular structure within stent at the stenotic site, OCT detected unusual bell-shaped image of late stent restenosis with extension of incomplete stent apposition.

Repetitive restenosis in a biodegradable polymer sirolimus-eluting stent with hypersensitivity reaction: a case report.

Project description:BackgroundHypersensitivity reaction is a classic cause of in-stent restenosis (ISR) in coronary stents, typically reported in bare-metal stents and first-generation drug-eluting stents. Biodegradable polymer sirolimus-eluting stent (BP-SES) was developed with the concept of biocompatibility, and there has been no report of ISR of BP-SES with hypersensitivity reaction.Case summaryAn 81-year-old woman presented with ST-elevation acute inferior myocardial infarction. Primary percutaneous coronary intervention was performed for the culprit lesion in the left circumflex artery with a permanent polymer everolimus-eluting stent (PP-EES), followed by BP-SES implantation in the left anterior descending artery. Eight months later, coronary angiography showed total occlusion of the PP-EES and diffuse ISR in the BP-SES, treated with a paclitaxel-eluting balloon. Fluorodeoxyglucose with positron emission tomography showed increased uptake around the BP-SES, and cardiac magnetic resonance imaging revealed a late gadolinium-enhanced area around both stents. Four months later, she developed re-ISR in the BP-SES, and optical coherence tomography demonstrated diffuse-layered neointimal hyperplasia with microvascularization and peri-strut low-intensity area. She was successfully treated with coronary artery bypass grafting.DiscussionOur case demonstrated repetitive short-term ISR of the BP-SES. Observation by both intravascular and non-invasive imaging modalities suggested the presence of hypersensitivity reaction localized in the stent. Hypersensitivity to the metal may be a possible mechanism because both stents are composed of L605 cobalt-chromium alloy. This is the first report of ISR of a BP-SES with hypersensitivity reaction. Non-invasive imaging can be useful to assess this critical condition.

Inflammation and Extracellular Matrix Genes Differentially Expressed Following Overlapping Zotarolimus- and Sirolimus-Eluting Stent Implantation

Project description:An unanticipated complication of the use of bare metal stents in percutaneous transluminal coronary angioplasty is in-stent restenosis resulting in >50% late lumen diameter loss in treated patients. In an effort to reduce in-stent restenosis, drug eluting stents containing the immunosuppressant sirolimus or zotarolimus have recently been developed. We report here the molecular response of arterial tissue to the implanting of these drug-eluting stents. Gene expression profiling was performed on 4 artery segments surrounding bare metal stents (BMS), 4 artery segments surrounding sirolimus-eluting stents (SES), and 4 artery segments surrounding zotarolimus-eluting stents (ZES) implanted into porcine animal models for 28 days.

Case series of coronary artery aneurysms after Everolimus eluting stent implantation and comparison with Sirolimus eluting stents.

Project description:BackgroundCoronary artery aneurysms after drug eluting stents are rare. We present a case series of type II coronary aneurysms after implantation of Everolimus eluting stents including patients developing giant aneurysms with a toxic course.Case presentationOver a span of 3.5 years at our center 2572 patients were implanted Everolimus eluting stents out of which 4 patients developed coronary type II aneurysms an incidence of 0.00156 whereas 5838 patients were implanted Sirolimus eluting 2nd generation stents out of which 2 patients developed similar aneurysms with an incidence of 0.00034. The slight increase in incidence in Everolimus stents does not reach statistical significance (p = 0.054) and is limited by single centre non randomized study. We also propose a hypothesis that the slight increase in the incidence maybe due to allergy to Methacrylate present in Everolimus eluting Xience stent's primer which is absent in other Sirolimus eluting stents used at our center but that needs to be further investigated. We also found some patients who developed giant aneurysms including Left main aneurysms. In our series operative repair of these patients had better outcomes than covered stent deployment but larger trials maybe needed to confirm the same.ConclusionsCoronary artery aneurysms after stent implantation are rare but occasionally giant aneurysms are formed with a toxic course. The incidence and morphology of aneurysms after Everolimus and Sirolimus eluting stent deployment do not differ much.

Peri-Contrast Staining as a Marker of Stent Failure: Restenosis, Thrombosis, and Fracture.

Project description:Peri-stent contrast staining (PSS), defined as contrast staining around the stent struts, has been identified as an indicator of future stent failure in first generation, sirolimus-eluting coronary stents. 1 PSS has been associated with in-stent restenosis, stent thrombosis, stent fracture, and the development of coronary aneurysm. As the frequency of patients with first generation sirolimus-eluting coronary stents becomes infrequent; PSS may go unrecognized. Herein, we present a patient with a decade of longitudinal follow-up, who developed PSS identified on coronary angiogram with recurrent stent failure.

Real-World Clinical Performance of a Novolimus-Eluting Stent Versus a Sirolimus-Eluting Stent.

Project description:IntroductionThe DESyne novolimus-eluting coronary stent (NES) is a new-generation drug-eluting stent (DES) that is widely used, but clinical data are rarely reported for this stent. We compared the safety and effectiveness of the DESyne NES and the Orsiro bioresorbable polymer sirolimus-eluting stent (SES) in patients undergoing percutaneous coronary intervention (PCI).MethodsThis was a retrospective, single-center, observational study. Between July 2017 and December 2022, patients who presented with chronic or acute coronary syndrome undergoing PCI with DESyne NES or Orsiro SES were consecutively enrolled in the present study. The primary endpoint, major adverse cardiovascular event (MACE), was a composite of cardiovascular death, target-vessel myocardial infarction, or clinically driven target-lesion revascularization.ResultsA total of 776 patients (age 68.8 ± 12.2; 75.9% male) undergoing PCI were included. Overall, 231 patients with 313 lesions received NES and 545 patients with 846 lesions received SES. During a follow-up duration of 784 ± 522 days, the primary endpoint occurred in 10 patients (4.3%) in the NES group and in 36 patients (6.6%) in the SES group. After multivariate adjustment, the risk of MACE did not significantly differ between groups (NES vs. SES, hazard ratio 0.74, 95% CI, 0.35-1.55, p = 0.425). The event rate of individual components of the primary endpoint was comparable between the two groups.ConclusionsFavorable and similar clinical outcomes were observed in patients undergoing PCI with either NES or SES in a medium-term follow-up duration. Future studies with adequately powered clinical endpoints are required for further evaluation.
