Failure of drug-coated balloon angioplasty to treat bare metal in-stent restenosis accompanied by late stent thrombosis but successful treatment of binary in-stent restenosis

Publication date: Available online 16 May 2019Source: Journal of Cardiology CasesAuthor(s): Takuya Shimizu, Jun-ei Obata, Ken Umetani, Kiyotaka KugiyamaAbstractDrug-coated balloons (DCB) are effective in treating in-stent restenosis (ISR) with neointimal proliferation after bare-metal stent (BMS) implantation, but it is unclear whether DCB are effective in treating BMS-ISR accompanied by thrombosis. An 84-year-old man with previous inferior myocardial infarction and atrial fibrillation developed acute myocardial infarction (AMI) during hospitalization for intracerebral hemorrhage. Emergent coronary angiography (CAG) revealed severe stenosis of the distal left circumflex coronary artery. We implanted a BMS to avoid long-term triple antithrombotic therapy. He received aspirin, clopidogrel, and rivaroxaban for 1 month and then received clopidogrel and rivaroxaban. Seventy days after BMS implantation, he developed AMI, and emergent CAG revealed occlusion of the BMS due to late stent thrombosis. After thrombus aspiration, intravascular ultrasound showed incomplete neointimal healing in the proximal portion of the stent and excessive neointimal proliferation in the distal portion of the stent. DCB angioplasty of the entire BMS was performed after scoring balloon pre-dilation. Seven months after BMS implantation, follow-up CAG revealed binary ISR. DCB angioplasty of the entire BMS was performed again after scoring balloon pre-dilation. Thirteen months after BMS implantation, follow-...

ConclusionIn patients with suspected AMI timely applying of MDCT, angiography, endovascular revascularization and ICG quality control of perfusion after revascularization are expedient to improve the results of treatment. These patients should be treated by a multidisciplinary team consisting of a cardiologist, a cardiovascular and endovascular surgeon, a general surgeon with experience in working with such patients.

This study evaluated whether compliance with the Atrial fibrillation Better Care (ABC) pathway for integrated care management ("A" Avoid stroke; "B" Better symptom management; "C" Cardiovascular risk and Comorbidity optimization) would improve population-based clinical outcomes in a nationwide AF cohort. METHODS AND RESULTS:  From the Korea National Health Insurance Service database, a total of 204,842 nonvalvular AF patients were enrolled between January 1, 2005 and December 31, 2015. Patients that fulfilled all criteria of the ABC pathway were defined as the "ABC" group, ...

This study sought to investigate what could be learned from how these men have fared. The men were born in 1925-1928 and similar health-related data from questionnaires, physical examination, and blood samples are available for all surveys. Survival curves over various variable strata were applied to evaluate the impact of individual risk factors and combinations of risk factors on all-cause deaths. At the end of 2018, 118 (16.0%) of the men had reached 90 years of age. Smoking in 1974 was the strongest single risk factor associated with survival, with observed percentages of men reaching 90 years being 26.3, 25.7, ...

Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this techniqu...

Conclusion: In ischemic stroke or TIA patients with platelet count within normal range, platelet count may be a qualified predictor for long-term recurrent stroke, mortality, and poor functional outcome. Introduction Platelets exert a critical role in the pathogenesis of atherosclerotic complications of cardio-cerebrovascular disease, contributing to thrombus formation, and embolism (1, 2). Previous literature reported that platelets of various size and density are produced by megakaryocytes of different size and stages of maturation in different clinical conditions, suggesting various platelet patterns in differen...

CONCLUSIONS: Low-dose prasugrel, as part of triple therapy, did not increase the risk of bleeding compared with clopidogrel. Therefore, it can be an alternative to clopidogrel for patients with AF undergoing PCI. PMID: 30918236 [PubMed - as supplied by publisher]

gro G Abstract Background: Combination of dual antiplatelet (DAPT) and oral anticoagulation therapy is required to decrease cardioembolic stroke and stent thrombosis risk in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS). We compared the safety and efficacy of dabigatran etexilate with vitamin K antagonist (VKA), in combination with DAPT (aspirin plus clopidogrel) treatment in AF patients who underwent percutaneous coronary intervention (PCI) with stenting for ACS. Methods: Consecutive nonvalvular AF patients who received twice-daily dabigatran 110 mg (n = 389) or VKA (n = 510) and D...

This study aimed to capture the evolving OAC patterns of patients with known non-valvular AF at high risk for stroke (CHA2DS2-Vasc score  ≥ 2 for males and ≥ 3 for females) during hospitalization. A total of 561 eligible patients who were admitted to the cardiology ward of a tertiary hospital were studied. Pre- and post-hospitalization OAC patterns [vitamin-K antagonist (VKA), non-vitamin K oral anticoagulants (NOAC), no OA C], changes between these patterns (initiation, switch, discontinuation, no change) and the respective patient profiles and discharge diagnoses were assessed. During hospitali...
