Drug-eluting stents have significantly improved the long-term outcomes of percutaneous coronary intervention (PCI) by decreasing the excessive growth of neointima. However, conventional stents have some limitations. PCI with a bioresorbable vascular scaffold (BVS) has emerged as an alternative since the presence of the prosthesis in the coronary artery is transient. A US Food and Drug Administration advisory panel of experts recommended approval of BVS based on the analysis of its risks and rewards in July 2016...

BACKGROUND: Nowadays, fraction flow reserve (FFR) is being discussed in every percutaneous coronary intervention (PCI) capable hospitals. Owing to recent development in the medical field, FFR-guided PCI should be able to find a place in Interventional Cardiology. At present, the importance of FFR to stratify patients who require PCI has seldom systematically been investigated. In this analysis, we aimed to compare the major adverse cardiac events (MACEs) mainly in patients with stable coronary artery disease (CAD) to whom PCI was recommended and deferred respectively based on the FFR value...

We present the case of a 69-year-old patient who was referred to the Department of Echocardiography for surgical treatment of severe tricuspid valve regurgitation (TVR) with advanced congestive heart failure. In 2013 the patient underwent unsuccessful percutaneous ablation for permanent atrial fibrillation. In 2015, following numerous episodes of atrial fibrillation and congestive heart failure with left pleural effusion, the patient was admitted to another center. A transthoracic echocardiogram showed severe TVR and moderate precapillary pulmonary hypertension, confirmed at right cardiac catheterization...

Neointimal hyperplasia is known as a main factor contributing to in-stent restenosis (ISR). Monocytes may play a central role in vessel restenosis process after stent implantation. The aim of this study was to investigate the relationships between the urokinase-type plasminogen activator (PLAU) and vitronectin (Vtn) gene expression levels in peripheral blood mononuclear cell samples isolated from whole blood of 66 patients undergoing coronary artery angiography (22 controls, stenosis < 0.05%; 22 with stent no-restenosis and stenosis < 70%; and 22 with ISR and stenosis > 70%)...

PURPOSE: Three-dimensional reconstruction of a vessel centerline from paired planar coronary angiographic images is critical to reconstruct the complex three-dimensional structure of the coronary artery lumen and the relative positioning of implanted devices. In this study, a new vessel centerline reconstruction method that can utilize non-isocentric and non-orthogonal pairs of angiographic images was developed and tested. METHODS: Our new method was developed in in vitro phantom models of bifurcated coronary artery with and without stent, and then tested in in vivo swine models (twelve coronary arteries)...

Tranexamic Acid (TXA), an antifibrinolytic, is routinely used to decrease transfusion rates in total joint replacement surgery. While recent publications have indicated a low risk of TXA-associated thromboembolic events in this orthopedic population, few studies specifically address the safety of TXA administration in high-risk patients. We present a case of acute coronary thrombus requiring emergent intervention in a patient with indwelling coronary stents who underwent shoulder arthroplasty with TXA administration...

This is a consensus document from the European Bifurcation Club concerning bench testing in coronary artery bifurcations. It is intended to provide guidelines for bench assessment of stents and other strategies in coronary bifurcation treatment where the United States Food and Drug Administration (FDA) or International Organization for Standardization (ISO) guidelines are limited or absent. These recommendations provide guidelines rather than a step-by-step manual. We provide data on the anatomy of bifurcations and elastic response of coronary arteries to aid model construction...

BACKGROUND: Traditional study design submitted to the Food and Drug Administration to test newer drug-eluting stents (DES) for marketing approval is the prospective randomized controlled trial. However, several DES have extensive clinical data from trials conducted outside the United States that have led to utilization of a novel design using the Bayesian approach. This design was proposed for testing DES with bioresorbable polymer compared with DES most commonly in use today that use durable polymers for drug elution...

Transradial (TR) access has been extensively compared to transfemoral (TF) access in patients undergoing percutaneous coronary interventions, with TR method showing a clear benefit over the latter. However, comparative data concerning peripheral artery endovascular interventions has been limited in the literature. Therefore, a systematic review was conducted in order to compare main outcomes between TR and TF access in patients undergoing peripheral artery angioplasty and/or stenting. Main outcomes included technical success, major/minor bleeding risk, access site complications, hospital stay, death, myocardial infarction, neurological events and other procedural parameters...

Local hemodynamic forces are well-known to modulate atherosclerotic evolution, which remains one of the largest cause of death worldwide. Percutaneous coronary interventions with stent implantation restores blood flow to the downstream myocardium and is only limited by stent failure caused by restenosis, stent thrombosis, or neoatherosclerosis. Cumulative evidence has shown that local hemodynamic forces affect restenosis and the platelet activation process, modulating the pathophysiological mechanisms that lead to stent failure...

BACKGROUND: Dual antiplatelet therapy (DAPT) with aspirin (ASP) and a P2Y12 blocker is currently standard care after percutaneous coronary intervention (PCI) with stent insertion, and aims to inhibit platelet function in order to prevent stent thrombosis. The P2Y12 blocker ticagrelor (TIC) has greater antiplatelet effect than the previously used members of this class, such as clopidogrel. In healthy volunteers, TIC is sufficient to cause strong platelet inhibition, with little additional effect from ASP...

This article gives an update on the management of acute ST-segment elevation myocardial infarction (STEMI) according to the recently released European Society of Cardiology guidelines 2017 and the modifications are compared to the previous STEMI guidelines from 2012. Primary percutaneous coronary intervention (PCI) remains the preferred reperfusion strategy. New guideline recommendations relate to the access site with a clear preference for the radial artery, use of drug-eluting stents over bare metal stents, complete revascularization during the index hospitalization, and avoidance of routine thrombus aspiration...
