BACKGROUND: Cancer patients with recently placed drug-eluting stents (DESs) often require premature dual antiplatelet therapy (DAPT) discontinuation for cancer-related procedures. Optical coherence tomography (OCT) can identify risk factors for stent thrombosis such as stent malapposition, incomplete strut coverage and in-stent restenosis and may help guide discontinuation of DAPT. METHODS: We conducted a single-center prospective study in cancer patients with recently placed (1-12 months) DES who required premature DAPT discontinuation...

OBJECTIVES: The presence of more severe white matter changes (WMC) may be associated with a higher risk of peri-procedural strokes in patients undergoing carotid artery stenting (CAS). However, to what extent WMC affects peri-procedural risk of CAS is unclear. We aimed to evaluate the effect of WMC on peri-procedural complications by modifying a CAS peri-procedural risk scale through adding the assessment of WMC. PATIENTS AND METHODS: A database of patients undergoing CAS was sampled from 2007 to 2014 in a single Chinese medical center...

BACKGROUND: Patients after cardiac arrest or in cardiogenic shock due to acute coronary syndrome (ACS) are at high risk for stent thrombosis (ST) and recurrent cardiovascular events after primary percutaneous coronary intervention (PCI). High post-interventional platelet reactivity (HPR) might be an additional risk factor for ST in these critically ill patients. METHODS: Between 2006 and 2016, 401 critically ill patients from a cardiologic intensive care unit underwent platelet function testing after primary PCI using whole blood impedance aggregometry...

BACKGROUND AND IMPORTANCE: Microguidewire entrapment and failure related to endovascular therapy is a rare complication with limited case reports available, most of which are from cardiac endovascular intervention. Migration of the microguidewire has been reported in coronary intervention with some resulting in severe complications, but there are no reported cases of spontaneous extrusion of wire fragment following a neurointerventional procedure. We report the first case of a microguidewire entrapment with subsequent fracture, followed by spontaneous extrusion of the wire fragment...

BACKGROUND: Drug-eluting stents (DES) represent a significant evolution in the treatment of patients with acute myocardial infarction with ST elevation. However, stent-related adverse events have led to an introduction of drug-coated balloons (DCB) applied particularly to bifurcation lesions, in-stent restenosis and small vessel disease. The aim of this study was to determine whether a DCB-only strategy has a similar safety profile and equal angiographic and clinical outcomes to DES implantation in primary percutaneous coronary intervention (pPCI)...

OBJECTIVES: To evaluate the 9-month safety and efficacy of polymer-free sirolimus eluting drug eluting stents in septuagenarians and octogenarians. METHODS: An all-comer, worldwide single armed trial (ClinicalTrials.gov Identifier NCT02629575) was conducted to demonstrate the safety and efficacy of an ultra-thin strut, polymer-free sirolimus eluting stent (PF-SES). The primary endpoint was the 9-month target revascularization rate (TLR). Secondary endpoints included the rates of major adverse cardiac events (MACE), stent thrombosis (ST) and bleeding (BARC) in septuagenarians (≥70 years, <80 years), and in octogenarians (≥80 years) to be compared to the younger patient group (<70 years)...

Every year 16 million operations are performed in Germany. Many patients take platelet aggregation inhibitors as a primary or secondary prevention to reduce the risk of cardiovascular events. Especially during the perioperative period, this risk reduction is relevant due to an increased risk for cardiac events (in approximately 6.2% of operations). As a result of a presumed increased risk of bleeding, platelet aggregation inhibitors are often paused perioperatively. Thus, doctors must decide on a risk-adapted basis whether the medication can be continued perioperatively and, if so, with what risks...

BACKGROUND: MiStent is a drug-eluting stent with a fully absorbable polymer coating containing and embedding a microcrystalline form of sirolimus into the vessel wall. It was developed to overcome the limitation of current durable polymer drug-eluting stents eluting amorphous sirolimus. The clinical effect of MiStent sirolimus-eluting stent compared with a durable polymer drug-eluting stents has not been investigated in a large randomised trial in an all-comer population. METHODS: We did a randomised, single-blind, multicentre, phase 3 study (DESSOLVE III) at 20 hospitals in Germany, France, Netherlands, and Poland...

Over the last decade, systems of care for ST-elevation myocardial infarction (STEMI) have evolved to try to improve outcomes and timely access to percutaneous coronary intervention (PCI). There have also been advances in PCI techniques and adjunctive pharmacotherapies. In this study, we sought to determine temporal changes in practices and clinical outcomes of PCI in patients with STEMI. We prospectively collected data on 8,412 consecutive patients undergoing PCI for STEMI between 2005 and 2016 in the multicenter Melbourne Interventional Group registry...
