The Fourth Universal Definition of Myocardial Infarction is a document developed jointly by the European Society of Cardiology (ESC), the American College of Cardiology (ACC), the American Heart Association (AHA), and the World Heart Federation (WHF). The Fourth Definition was necessary for multiple reasons, including increasingly higher troponin sensitivity. While troponin obviously does not...
Despite our high hopes for new-generation drug-eluting stents (DES), patients with diabetes still have a different prognosis, both clinical and angiographic, compared with non-diabetic patients. Authors sought to investigate the impact of diabetes on patients who underwent drug-eluting stent implantation in the BIONICS (BioNIR Ridaforolimus Eluting Coronary Stent System in Coronary Stenosis) trial. This...
1- Everolimus-Eluting Stents Finally Have a Rival and Not Just a “Non-Inferior” Stent In this large randomized trial, there were significant differences as regards both target-lesion failure and target-vessel-related infarction, which persisted through a 2-year follow-up and favored treatment with an ultrathin-strut bioresorbable-polymer sirolimus-eluting stent (Orsiro) compared with the gold standard, a durable-polymer everolimus-eluting stent...
The potential need for a 7-Fr guidewire, the use of several coronary guidewires and/or a kissing balloon, and the requirement of indispensable monitoring by intravascular ultrasound (IVUS) have been used by some interventional cardiologists as excuses to resist radial access. In that sense, left main coronary artery angioplasty was the last stand of femoral access....
We often inform our patients we should first approach the superficial femoral with an endovascular intervention, and that should it fail or develop restenosis, we could always resort to a bypass. We were not lying when we’d assume a bypass following endovascular intervention would have the same outcome as a primary bypass. Simply put, no...
Luminal thrombotic occlusions associated with non-significant atherosclerosis are commonly observed in patients with critical lower limb ischemia, which suggests the possibility of thromboembolic disease as a great contributor to ischemia. This was particularly verifiable in infrapopliteal vessels, thus showing a possible mechanism of progression from peripheral vascular disease to critical ischemia, as well as a...
Polymer-free amphilimus-eluting stents are a novel technology combining sirolimus and long-chained fatty acids. This enhances the uptake of antiproliferative agents and may be associated with lower restenosis, particularly among patients with diabetes. The new device includes abluminal reservoirs filled with the drug; in consequence, there is no need for polymer. This work compares this new...
Polymer persistence in 1st and 2nd generation DES meant to allow drug release has been associated with a chronic inflammatory response that might be associated to restenosis, neo atherosclerosis and stent thrombosis. This is the rationale behind the development of polymer free and bioresorbable polymer-based DES. They have both been compared against permanent polymer DES,...
The LEADERS FREE trial demonstrated that a polymer-free Biolimus A9-coated stent (BioFreedom™DCS; Biosensors Europe, Morges, Switzerland) is superior to a conventional stent (bare metal stent, BMS) in patients with high bleeding risk treated with only one month of dual antiplatelet therapy. Now, is this global study outcome applicable in cases of complex lesions with several...
This study aimed to assess the outcome of Culotte stenting with newer-generation drug-eluting stents (DES) in Medina 1, 1, 1 bifurcation lesions. The 2nd-generation device used was permanent-polymer everolimus-eluting stent Xience, a device for which there is comparatively plenty of evidence available. Alternatively, the 3rd-generation stent used was thin-strut abluminal bioresorbable-polymer everolimus-eluting stent SYNERGY. Patients with...
