Aim. Diabetes mellitus (DM) is a major risk factor for cardiovascular disease. The implications of a diagnosis of DM are as severe as the diagnosis of coronary artery disease. For many patients with complex coronary artery disease, optimal revascularization strategy selection and optimal medical therapy are equally important. In this study, we compared the hemodynamic results of different stenting techniques for Medina 0,1,0 left main bifurcation lesions. Methods. We use idealized left main bifurcation models and computational fluid dynamics analysis to evaluate hemodynamic parameters which are known to affect the risk of restenosis and thrombosis at stented bifurcation...

We report a case of percutaneous coronary intervention in a bifurcation lesion involving left circumflex (LCx) artery and 2 major posterolateral (PL) arteries. The target LCx had diffuse long and severely calcified lesion with the acute takeoff angle from the left main. Despite adequate lesion preparation with rotational atherectomy and balloon angioplasty, the stent was not deliverable, even with deep intubation of 7Fr-guiding catheter. Conventional use of guiding extension catheter (GEC) would have required removal of a wire from at least one PL because of the device interference in the GEC...

Drug-eluting balloons (DEB) may be considered as a "quiet revolution" in percutaneous coronary interventions. Early-generation DEB eluting paclitaxel proved to be very effective in animal models to reduce neointimal hyperplasia. Areas covered: Review of DEB efficacy in patients with coronary de novo lesions and in-stent restenosis (ISR). Expert opinion: Many randomized clinical trials and meta-analyses have demonstrated the value of DEB in patients with ISR. In this setting, DEB are safe and effective with clinical and angiographic results superior to plain balloon angioplasty and at least equivalent to first generation drug-eluting stents (DES)...

A 66-year-old male was treated percutaneously for a bifurcation lesion of the left anterior descending coronary artery by provisional stenting using the jailed wire technique. After successfully stenting the main branch, retraction of the looped main branch guidewire was impossible. After using an intravascular ultrasound we discovered the guidewire was entangled with a stent strut. Thereafter, the proximal stent elongated after retraction. With the support of an over-the-wire microcatheter, we finally pulled out the entrapped guidewire...

Although uncommon, critical hand ischemia (CHI) represents a cause of significant disability because of its effect on hand function. Percutaneous transluminal angioplasty (PTA) is now considered a first-line therapy for above-the-elbow artery disease while there are few data regarding the treatment of below-the-elbow (BTE) arteries. The aim of this study is to review the current literature on BTE vessel PTA and to describe the technical approach. In case of favorable anatomy (absence of inflow arteries disease, standard humeral artery bifurcation), a 4-F antegrade trans-brachial approach is usually the preferred option...

OBJECTIVES: This observational study assessed the 9-month clinical outcomes in patients with coronary bifurcation lesions suitable for drug-coated balloon (DCB) angioplasty. It was the intention to use DCB's without additional stenting (DCB-only strategy) in selected patients for this chosen strategy. Bail-out main branch (MB) and/or side branch (SB) stenting, however, were permissible when flow limiting dissections or excessive recoil occurred. BACKGROUND: A multitude of interventional strategies have been studied to treat bifurcation lesions...

OBJECTIVES: We propose a right lateral (90-120° RAO) with 30° cranial angiographic view to expose the bifurcation of the left main coronary artery (LMCA) when previously used routine projections were inefficient at clearly showing this region. BACKGROUND: Little has been published in the medical literature regarding angiographic projections dedicated to special anatomies. METHODS: A total of 84 patients were subjected to the proposed projections...

OBJECTIVES: To investigate the value of rotational coronary angiography (RoCA) in the context of percutaneous coronary intervention (PCI) planning. BACKGROUND: As a diagnostic tool, RoCA is associated with decreased patient irradiation and contrast use compared with conventional coronary angiography (CA) and provides superior appreciation of three-dimensional anatomy. However, its value in PCI remains unknown. METHODS: We studied stable coronary artery disease assessment and PCI planning by interventional cardiologists...

BACKGROUND: Results of regular drug-eluting stents (rDESs) in bifurcation treatment are not optimal. The aim of the Polish Bifurcation Optimal Stenting I (POLBOS I) trial was to compare bifurcation treatment with any rDES vs the dedicated bifurcation paclitaxel-eluting stent BiOSS Expert (Balton, Poland). The second aim was to study the effect of final kissing balloon (FKB) inflation on clinical outcomes. METHODS: Between October 2010 and January 2013 patients with stable coronary artery disease or non-ST-elevation acute coronary syndrome were assigned 1:1 to 1 of 2 treatment strategies: BiOSS Expert stent or rDES implantation...

BACKGROUND: Bifurcation lesions are frequent among patients with symptomatic coronary disease treated by percutaneous coronary intervention. Current evidence recommends a conservative (provisional) approach when treating the side branch (SB). OBJECTIVES: The TRYTON (Prospective, Single Blind, Randomized Controlled Study to Evaluate the Safety & Effectiveness of the Tryton Side Branch Stent Used With DES in Treatment of de Novo Bifurcation Lesions in the Main Branch & Side Branch in Native Coronaries) bifurcation trial sought to compare treatment of de novo true bifurcation lesions using a dedicated bifurcation stent or SB balloon angioplasty...

PURPOSE: The paper presents the process of numerical modeling and simulation of balloon angioplasty of the coronary artery using Finite Element Method. METHODS: The authors focused on the issue of applying adequate pressure in an arterial tissue during the post-dilatation process in the "kissing balloon" stenting technique applied to patients with bifurcation stenosis. Despite great progress in the field of interventional cardiology, angioplasty in bifurcations still belongs to the most difficult interventions, generally being less effective and more risky than in the cases of straight stenosis...

BACKGROUND: To improve clinical outcomes after percutaneous coronary interventions of coronary bifurcation lesions, the Tryton Side Branch Stent™ (Tryton Medical, Durham) was developed. Registry studies evaluating the Tryton stent has shown promisingclinical results and the stent is currently compared with the provisional single stent strategy in a randomized trial. However, clinical results beyond one year are lacking, and therefore, we investigated the one- and two-year outcomes after Tryton stent placement in a single-center registry study...
