BACKGROUND: Subclavian artery stenosis (SAS) is narrowing of the subclavian artery most commonly caused by atherosclerosis. It serves as a marker for cerebrovascular and myocardial ischemic events. METHODS: A retrospective cohort study was conducted to determine the association of treatment via combination therapy (antiplatelet drug plus either by-pass surgery or percutaneous transluminal angioplasty (PTA) with or without stent implantation) versus antiplatelet drug therapy alone on cardiovascular events and all-cause mortality in Marshfield Clinic patients diagnosed with symptomatic SAS from January 1, 1995 to December 31, 2009...

Contrast-induced thrombocytopenia is a rare complication distinguished by acute and severe platelet consumption, with spontaneous recovery within days. We describe a case of acute thrombocytopenia 6 hours after coronary angioplasty in a patient with a negative antiplatelet factor 4 test. The count reached 1 × 10(3)/µL, but improved spontaneously to 210 × 10(3)/µL after 8 days. In conclusion, physicians should be aware of this complication, particularly when dual antiplatelet therapy is being considered...

Troponin elevation after coronary angioplasty is a prognostic marker associated with significant morbidity and mortality, although its prevalence varies according to clinical and procedural characteristics. We analyzed the frequency of post-procedural enzyme elevation among 112 elective interventions between 2013 and 2014 in a private hospital in Brazil. Troponin increase was observed in 62.5% of the procedures, and was related to age, female sex, low pre-procedural hemoglobin, prior angiotensin converting enzyme inhibitor or angiotensin receptor blocker use and multivessel angioplasty...

BACKGROUND: Acute kidney injury (AKI) following primary percutaneous coronary intervention (pPCI) is frequently interpreted as contrast-induced AKI but may result from other insults. We aimed to determine the causal association of contrast material exposure and the incidence of AKI following pPCI using a control group of propensity score-matched patients with ST-segment-elevation myocardial infarction who were not exposed to contrast material. METHODS AND RESULTS: We studied 2025 patients with ST-segment-elevation myocardial infarction who underwent pPCI and 1025 patients receiving fibrinolysis or no reperfusion who were not exposed to contrast material during the first 72 hours of hospital stay (control group)...

Melatonin, an endogenously produced hormone, might potentially limit the ischemia reperfusion injury and improve the efficacy of mechanical reperfusion with primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI). This study was aimed to evaluate whether the treatment effect of melatonin therapy in patients with STEMI is influenced by the time to administration. We performed a post hoc analysis of the Melatonin Adjunct in the Acute Myocardial Infarction Treated With Angioplasty trial (NCT00640094), which randomized STEMI patients to melatonin (intravenous and intracoronary bolus) or placebo during pPCI...

Triple antithrombotic therapy (TAT), consisting of aspirin, a P2Y12 receptor antagonist and oral anticoagulant (OAC) medication has been considered as an 'unavoidable' strategy for a 1-12 months for atrial fibrillation (AF) patients post acute coronary syndrome or percutaneous coronary angioplasty with stenting. However, TAT has rather poorly been adopted in real life practice, mainly because of an accompanying increased bleeding potential and lack of definitive results of randomized clinical trials. Several registries, meta-analyses and small randomized trials have so far provided the base of guidelines recommendations...

INTRODUCTION: Local thrombolysis with a time of exposure to recombinant tissue plasminogen activator of 15 to 150 minutes is commonly used to declot acutely thrombosed hemodialysis fistulas. The duration of thrombolysis for the restoration of arteriovenous blood flow remains controversial. The aim of this study was to investigate the outcomes of long thrombolysis treatment (LTT, 3 hours or more) and short thrombolysis treatment (STT, less than 3 hours) in our institution. METHODS: We retrospectively analyzed 86 interventional declotting procedures (28 STT and 58 LTT) applied to 86 acutely thrombosed hemodialysis fistulas...

The aim of the present study is to analyse quantitatively the potential reduction of the doses to eye lens and the hands of an operator and a nurse by the pelvic lead blanket during coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) procedures. Thermoluminescent dosimeters (TLDs) were used to assess dose levels to left eye lens and left and right fingers of both physician and nurses during single procedures performed with or without lead blanket. The measurements were carried out in one medical centre and include dosimetric data from100 procedures...

Cardiovascular complications, in particular perioperative myocardial infarctions, are central contributors to morbidity and mortality after non-cardiac surgery. We present a case of a 41-year-old male, smoker and dyslipidemic, who underwent bimaxillary orthognathic jaw surgery with the development of an acute coronary syndrome in the immediate postoperative period. We managed to early diagnose the myocardial infarction and promptly performed a percutaneous transluminal coronary angioplasty, resulting in a positive outcome...

OBJECTIVES: To report adverse event rates after rotational atherectomy (RA) with contemporary drug-eluting stent (DES) implantation and compare RA to cutting balloon (CB) angioplasty and balloon-only angioplasty (BA) in the all-comers ADAPT-DES trial. BACKGROUND: Percutaneous coronary intervention (PCI) of calcified lesions is increasingly common and is associated with a high risk of adverse events. RA can ablate calcified plaque and facilitate stent delivery; however, in conjunction with first-generation DES, RA was not superior to BA alone in regard to adverse events...

OBJECTIVE: An arteriovenous bridging graft is a viable option for patients with compromised arteries or veins because of advanced age or diabetes. Arteriovenous graft with graft insertion anastomosis (AVGI) is the novel technique for graft-vein anastomosis where the prosthesis is inserted into the vein, and the anastomosis is performed on the surface of the prosthesis. This study assessed the short-term and long-term results of AVGI to clarify the efficacy of this technique. METHODS: Between 2010 and 2015, AVGI was performed in graft-vein anastomosis of prosthetic forearm loop access...

Introduction In traditional locations, the standard Blalock-Taussig shunt presents numerous technical difficulties for percutaneous intervention. We changed our strategy to a central type shunt (Laks-type) with end-to-side pulmonary and side-to-side aortic anastomosis. The aim of this study was to determine whether this modified strategy would allow easier percutaneous manipulation in patients with small pulmonary arteries. Methods All children with a stretchable central vascular graft who required any form of percutaneous intervention were prospectively enrolled in the study...
