Vascular restenosis following angioplasty continues to pose a significant challenge. The heterocyclic trioxirane compound [1, 3, 5-tris((oxiran-2-yl)methyl)-1, 3, 5-triazinane-2, 4, 6-trione (TGIC)], known for its anticancer activity, was utilized as the parent ring to conjugate with a non-steroidal anti-inflammatory drug, resulting in the creation of the spliced conjugated compound BY1. We found that BY1 induced ferroptosis in VSMCs as well as in neointima hyperplasia. Furthermore, ferroptosis inducers amplified BY1-induced cell death, while inhibitors mitigated it, indicating the contribution of ferroptosis to BY1-induced cell death...

Fully bioresorbable vascular scaffolds (BVSs) aim to overcome the limitations of metallic drug-eluting stents (DESs). However, polymer-based BVSs, such as Abbott's Absorb, the only US FDA-approved BVS, have had limited use due to increased strut thickness (157 μm for Absorb), exacerbated tissue inflammation, and increased risk of major cardiac events leading to inferior clinical performance when compared to metallic DESs. Herein we report the development of a drug-eluting BVS (DE-BVS) through the innovative use of a photopolymerizable, citrate-based biomaterial and a high-precision additive manufacturing process...

OBJECTIVE: The aim of this study was to compare the efficacy of different endovascular revascularisation procedures for treating chronic limb threatening ischaemia (CLTI) using network meta-analysis (NMA). DATA SOURCES: The databases PubMed and Cochrane Central Register for Controlled Trials were searched on 14 March 2023. REVIEW METHODS: A NMA of randomised controlled trials (RCTs) reporting the efficacy of different endovascular revascularisation techniques for treating CLTI was performed according to PRISMA guidelines...

BACKGROUND: Limited comparative data exist on different interventional strategies for endovascular revascularization of complex femoropopliteal interventions. OBJECTIVES: In this study, the authors aimed to compare a stent-avoiding (SA) vs a stent-preferred (SP) strategy, promoting optimal lesion preparation and the use of drug-eluting technologies in both arms. METHODS: Within a prospective, multicenter, pilot study, 120 patients with symptomatic complex femoropopliteal lesions (Rutherford classification 2-4, mean lesion length 187...

The efficacy of drug-coated balloons (DCB) versus drug-eluting stents (DES) for coronary artery disease (CAD) remains inconclusive. Despite paclitaxel's common use in both DES and DCB, there is a lack of meta-analyses comparing paclitaxel-eluting stents (PES) and paclitaxel-coated balloons (PCB). This meta-analysis aimed to evaluate and compare the outcomes of DES and DCB with paclitaxel. A systematic literature search of the Medline and Cochrane databases yielded six randomized controlled trials with 951 patients (1:1 ratio)...

BACKGROUND: The treatment of in-stent restenosis (ISR) after drug-eluting stent (DES) implantation remains challenging in current clinical practice. AIMS: The study was conducted to investigate a novel biolimus-coated balloon (BCB) for the treatment of coronary DES-ISR compared with the best-investigated paclitaxel-coated balloon (PCB). METHODS: This was a prospective, multicentre, randomised, non-inferiority trial comparing a novel BCB with a clinically proven PCB for coronary DES-ISR...

BACKGROUND: Drug-eluting devices improved outcomes of endovascular therapy (EVT) for femoropopliteal lesions, but mainly for de novo lesions. Endovascular therapy for in-stent restenosis/occlusion (ISR/O) is challenging, and large trials and long-term data are not well reported. MATERIALS AND METHODS: This study is a physician initiated, multicenter, and retrospective design. From 7 Japanese institutes, 3635 femoropopliteal cases were enrolled in the study. Among these, 346 cases of first ISR/O were studied...

OBJECTIVES: The aim of this study is to investigate the safety and efficacy of excimer laser coronary angioplasty (ELCA) combined with drug-coated balloons (DCBs) in the treatment of in-stent restenosis (ISR), and to explore whether the contrast injection technique would improve the neointimal tissue ablation of ELCA. METHODS: We studied patients diagnosed with ISR between January 2019 and October 2022 at two medical centers. These patients underwent DCB angioplasty guided by optical coherence tomography (OCT)...

OBJECTIVES: Data on side-branch (SB) ostial effect after drug-coated balloon (DCB) treatment in the context of de novo coronary bifurcation lesions are limited. We aimed to investigate the angiographic outcomes of SB ostium after DCB treatment compared with drug-eluting stents (DESs) implantation in the main vessel (MV) or optimal medical therapy (OMT) for the treatment of de novo coronary bifurcation lesions. METHODS: Serial angiographic changes in the SB ostium were compared between DCB, DES, and medication alone for MV treatment...

BACKGROUND: Late lumen enlargement (LLE) - a positive remodelling phenomenon - after drug-coated balloon (DCB) angioplasty for stable coronary disease contributes to a lower restenosis rate. However, lesion characteristics promoting LLE remain unclear. AIMS: This study aimed to investigate predictive lesion characteristics for LLE using serial optical frequency domain imaging (OFDI) following DCB angioplasty for de novo coronary artery lesions. METHODS: This retrospective, single-centre observational study included patients with angina pectoris who underwent paclitaxel-coated balloon angioplasty without stenting under OFDI guidance as well as follow-up OFDI...

BACKGROUND: Partial anomalous pulmonary venous return (PAPVR) can be surgically corrected using a pericardial baffle. This baffle can become obstructed post-surgery, leading to pulmonary hypertension and right heart dysfunction if not detected and corrected. CASE SUMMARY: We describe three patients with occluded PAPVR baffles who underwent drug-coated balloon angioplasty and stenting of the obstructed baffle. In each case, baffle obstruction was detected post-operatively on surveillance cross-sectional imaging, and an invasively measured pulmonary capillary wedge-to-left atrium gradient was noted to be elevated...

OBJECTIVES: With the development of endovascular therapies, some studies have indicated a therapeutic potential for infrapopliteal arterial revascularization with atherectomy (AT). This study was designed to perform a meta-analysis to investigate the efficacy of AT combined with percutaneous transluminal angioplasty (PTA) or drug-coated balloon (DCB) compared with PTA or DCB for infrapopliteal arterial diseases. METHODS: This is a systematic review and meta-analysis...

This case report presents the first use of Optilume® drug-coated balloon (DCB) technology for the management of post-transurethral resection of the prostate bladder neck contracture (BNC), a condition often resistant to traditional treatments. A 62-year-old male with recurrent BNC, unresponsive to multiple operative interventions, underwent treatment with the Optilume® DCB, resulting in significant symptom resolution without further invasive procedures. This novel application of DCB technology, delivering paclitaxel directly to the affected tissue, offers a promising alternative by targeting the underlying pathophysiology of BNC...

BACKGROUND: Intravascular lithotripsy (IVL) represents a novel approach in the management of coronary calcification. This technique employs acoustic pressure waves, generated by a shockwave balloon, to effectively fracture both superficial and deep calcification in situ. The efficacy and safety of IVL have been convincingly demonstrated through the Disrupt CAD I-IV studies. While IVL is associated with the occurrence of atrial and ventricular arrhythmias, there is no evidence to indicate it causes myocardial ischemia...

PURPOSE: To compare patency and reintervention outcomes following either POBA or DCBA for venous stenoses after percutaneous AV fistula creation. MATERIALS AND METHODS: One-hundred and ninety-five pAVFs were successfully created during the study period; 141 using Ellipsys® and 54 using WavelinQTM . Post pAVF creation, 95 patients (48.7%) required secondary PTA with either POBA (n=55, 58%) or DCBA (n=40, 42.1%). The most common site for PTA was the juxta-anastomotic segment (75...

The superiority of drug-coated balloon (DCB) in treating small vessels, branching lesions, and high-risk bleeding lesions in coronary heart disease patients has been confirmed. However, its safety and efficacy in large vessels are still unclear. We aimed to investigate whether the efficacy of DCB in large vessels is not inferior to that of drug-eluting stent (DES). From November 2019 to April 2022, a total of 88 patients in our hospital who underwent coronary angiography for the first time and decided to receive DCB or DES treatment were selected...

In-stent restenosis (ISR) remains the primary cause of target lesion failure following percutaneous coronary intervention (PCI), resulting in 10-year incidences of target lesion revascularization at a rate of approximately 20%. The treatment of ISR is challenging due to its inherent propensity for recurrence and varying susceptibility to available strategies, influenced by a complex interplay between clinical and lesion-specific conditions. Given the multiple mechanisms contributing to the development of ISR, proper identification of the underlying substrate, especially by using intravascular imaging, becomes pivotal as it can indicate distinct therapeutic requirements...
