Efficacy and safety of drug-coated balloons according to coronary vessel size. A report from the BASKET-SMALL 2 trial. Adv Cardiol 2022; 18:122-130. [PMID: 36051841 PMCID: PMC9421526 DOI: 10.5114/aic.2022.118528] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Accepted: 07/18/2022] [Indexed: 11/17/2022]
Abstract
Introduction In BASKET-SMALL 2, drug-coated balloons (DCB) were non-inferior to drug-eluting stents (DES) in de-novo stenosis of small coronary vessels (≤ 2.75 mm) regarding clinical endpoints up to 36 months. Aim In the present subgroup analysis, we aimed to analyze the effect of the two treatment strategies in different vessel sizes. Material and methods Patients were analyzed according to the size of the device used (small > 2.5 mm vs. very small ≤ 2.5 mm). The primary endpoint was major adverse cardiac events (MACE), while secondary endpoints were target vessel revascularization (TVR), non-fatal myocardial infarction, cardiac death, and all-cause mortality, all at 36 months. Interactions for the different groups were assessed with Cox regression analysis. Results Overall, 758 patients were enrolled in this analysis, of which 437 (58%) had very small vessel disease. There were similar results in both treatment groups for the primary endpoint in both small and very small vessels (DCB vs DES, MACE at 3 years in small vessels HR = 1.31, 95% CI: 0.74–2.32, p = 0.355, and very small vessels HR = 0.82, 95% CI: 0.49–1.39, p = 0.468). Second generation paclitaxel-eluting stents showed significantly higher rates for MACE (p = 0.041), TVR (p = 0.004) and non-fatal myocardial infarction (p = 0.036) compared to DCB in very small coronary arteries at 3 years, while results were similar in small coronary arteries. Conclusions Efficacy and safety of DCB are similar irrespective of vessel size. However, there is a beneficial effect of DCB over paclitaxel-eluting stents regarding TVR, non-fatal myocardial infarction and MACE that is most pronounced in very small coronary arteries.

Impact of optimal preparation before drug-coated balloon dilatation for de novo lesion in patients with coronary artery disease. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2021; 35:91-95. [PMID: 33766488 DOI: 10.1016/j.carrev.2021.03.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Revised: 03/08/2021] [Accepted: 03/15/2021] [Indexed: 11/03/2022]
Abstract
BACKGROUND Drug eluting stent (DES) remain several problems, including stent thrombosis, stent fracture and neoatherosclerosis. Stent-less Percutaneous coronary intervention (PCI) using a drug coated balloon (DCB) is a stent-less strategy, and several trials have supported the efficacy of DCB. However, the optimal preparation before using DCB was uncertain. The aim of this study was to investigate the optimal preparation for plaque oppression/debulking before DCB dilatation for de novo coronary artery lesion. METHODS A total 936 patients were treated using DCB from 2014 to 2017 at our institution. Among them, we analyzed 247 patients who underwent PCI using DCB alone for de novo lesion. The primary end point of this study was target lesion failure (TLF). RESULTS The area under the receiver operating characteristic (ROC) curve (AUC) was used to determine the optimal cutoff value of % plaque area to predict TLF. ROC curve analysis revealed plaque area ≥ 58.5% (AUC, 0.81) were associated with TLF. Eligible 188 patients were divided into 2 groups (plaque area ≥ 58.5% [n = 38] and <58.5% [n = 150]) according to IVUS data before using DCB. TLF was significantly higher in plaque area ≥ 58.5% group than in <58.5% group (P < 0.01). Multivariable analysis selected plaque area ≥ 58.5% as an independent predictor of TLF (hazard ratio 7.59, P < 0.01). CONCLUSIONS Lesion preparation achieving plaque area < 58.5% was important in stent-less PCI using DCB.

Abstract
Clinical outcomes after percutaneous coronary intervention (PCI) for severely calcified lesions remain poor. The purpose of this study was to investigate the neointimal response after everolimus-eluting stents (EES) for severely calcified lesions treated with rotational atherectomy (RA) using optical coherence tomography (OCT).We retrospectively analyzed 34 lesions in which PCI was performed with EES deployment following RA and OCT was performed immediately after PCI and at follow-up (nine months). The EES was either durable-polymer (DP) EES (22 lesions) or bioabsorbable polymer (BP) -EES (12 lesions). Strut coverage and malapposition were evaluated at 1-mm intervals of cross-section (CS) by serial OCT analysis. Malapposed strut was defined as having the distance from luminal border > 100 μm.A total of 11,823 struts immediately after PCI and 11,720 struts at follow-up were analyzed. Immediately after PCI, the strut-level analysis showed no significant differences in the percentage of malapposed struts between the DP-EES group and the BP-EES group. At follow-up, the BP-EES group showed a more prevalent covered strut compared with the DP-EES group (strut-level analysis: 95% versus 97%, P = 0.045; CS-level analysis: 97% versus 100%, P < 0.01; lesion-level analysis: 27% versus 83%, P < 0.01, respectively).In severely calcified lesions requiring RA, the BP-EES group achieved better neointimal coverage than the DP-EES group at nine months. Additional prospective studies are needed.

Abstract
OBJECTIVE Approximately, 10-20% of patients with drug eluting stent (DES) in-stent restenosis (ISR) will develop recurrent ISR; yet, the optimal management of recurrent DES-ISR is unknown. We sought to compare the outcomes of recurrent DES-ISR treated with drug eluting balloons (DEB) to those with repeated implantation of new-generation DES. METHODS A total of 172 patients with recurrent DES-ISR were enrolled and stratified into two cohorts: the repeated DES implantation (Re-DES) group and the DEB group. The primary endpoint was the 1-year incidence of major adverse cardiovascular events (MACE). RESULTS Ninety-three patients treated with DEB and 79 patients with Re-DES implantation were analyzed. Both groups had comparable baseline characteristics. Lesser residual stenosis was achieved in the Re-DES group (11.3 ± 3.2% vs. 22.4 ± 4.3%; P = 0.00) than in the DEB group. However, the incidence of MACE and target lesion revascularization (TLR) were less in the DEB group (17.2% vs. 32.9%; P = 0.02 and 15.1% vs. 27.8%; P = 0.04, respectively). For the ≥3 metal-layered DES-ISR subgroup, DEB drastically reduced the incidences of MACE and TLR compared with Re-DES (20.0% vs. 57.9%; P = 0.02 and 16.0% vs. 47.4%; P = 0.04, respectively). Survival analysis demonstrated that MACE-free survival was significantly higher in the DEB group compared with the Re-DES group, whether the metal layers were ≥3 or 2. Multivariate analysis revealed that the risk factors of MACE were diabetes mellitus, ≥3 metal-layered DES ISR, and repeat DES deployment. CONCLUSIONS For recurrent DES-ISR, DEB may improve clinical outcomes compared with Re-DES implantation, especially for ≥3 metal-layered DES-ISR.

Abstract
The occurrence of in-stent restenosis (ISR) still remains a daunting challenge in the current era, despite advancements in coronary intervention technology. The authors explore the underlying pathophysiology and mechanisms behind ISR, and describe how the use of different diagnostic tools helps to best elucidate these. They propose a simplistic algorithm to manage ISR, including a focus on how treatment strategies should be selected and a description of the contemporary technologies available. This article aims to provide a comprehensive outline of ISR that can be translated into evidence-based routine clinical practice, with the aim of providing the best outcomes for patients.

Abstract
The lumen diameter reduction after percutaneous coronary intervention (PCI) is well known as "restenosis". This phenomenon is due to vessel remodeling/recoil in case of no-stent strategy or, in case of stent employ, "neointimal proliferation" that consists in an excessive tissue proliferation in the luminal surface of the stent otherwise by a further new-occurring atherosclerotic process called "neoatherosclerosis". The exact incidence of in-stent restenosis (ISR) is not easy to determine caused by different clinical, angiographic and operative factors. In the pre-stent era the occurrence of restenosis ranged between 32-55% of all angioplasties, and drop to successively 17-41% in the bare metal stents (BMS) era. The advent of drug-eluting stent (DES), especially 2nd generation, and drug-coated balloon (DCB) further reduce restenosis rate until <10%. We here review the main characteristics of this common complication of coronary interventions, from its pathogenesis to the most appropriate treatment strategy.

Abstract
Lung cancer being the most prevalent malignancy in men and the 3(rd) most frequent in women is still associated with dismal prognosis due to advanced disease at the time of diagnosis. Novel targeted therapies are already on the market and several others are under investigation. However non-specific cytotoxic agents still remain the cornerstone of treatment for many patients. Central airways stenosis or obstruction may often complicate and decrease quality of life and survival of these patients. Interventional pulmonology modalities (mainly debulking and stent placement) can alleviate symptoms related to airways stenosis and improve the quality of life of patients. Mitomycin C and sirolimus have been observed to assist a successful stent placement by reducing granuloma tissue formation. Additionally, these drugs enhance the normal tissue ability against cancer cell infiltration. In this mini review we will concentrate on mitomycin C and sirolimus and their use in stent placement.

Abstract
Stent thrombosis is an example of device-induced, platelet-mediated arterial thrombosis with a potentially fatal adverse event that often leads to myocardial infarction and/or death. The optimal treatment of patients with drug-eluting stent thrombosis in whom mechanical thrombectomy has failed is not established. This case demonstrates the usefulness of intracoronary thrombolysis after failed mechanical thrombectomy in patients with stent thrombosis. To our knowledge, this is the first report on using intracoronary thrombolysis in this specific situation.

Abstract
Tracheal stenosis due to either benign or malignant disease is a situation that the pulmonary physicians and thoracic surgeons have to cope in their everyday clinical practice. In the case where tracheal stenosis is caused due to malignancy mini-interventional interventions with laser, apc, cryoprobe, balloon dilation or with combination of more than one equipment and technique can be used. On the other hand, in the case of a benign disease such as; tracheomalacia the clinician can immediately upon diagnosis proceed to the stent placement. In both situations however; it has been observed that the stents induce formation of granuloma tissue in both or one end of the stent. Therefore a frequent evaluation of the patient is necessary, taking also into account the nature of the primary disease. Evaluation methodologies identifying different types and extent of the trachea stenosis have been previously published. However; we still do not have an effective adjuvant therapy to prevent granuloma tissue formation or prolong already treated granuloma lesions. There have been proposed many mechanisms which induce the abnormal growth of the local tissue, such as; local pressure, local stress, inflammation and vascular endothelial growth factor overexpression. Immunomodulatory agents inhibiting the mTOR pathway are capable of inhibiting the inflammatory cascade locally. In the current mini-review we will try to present the current knowledge of drug eluting stents inhibiting the mTOR pathway and propose a future application of these stents as a local anti-proliferative treatment.
