INTRODUCTION: Prior studies of ULM STEMI have been confined to small cohorts. Recent registry data with larger patient cohorts have shown contrasting results. We aim to study the outcomes of patients with unprotected left main (ULM) ST-elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI). METHODS: The Asia-pacific left main ST-Elevation Registry (ASTER) is a multicenter retrospective registry involving 4 sites in Singapore, South Korea, and the United States...

BACKGROUND: There are limited data on the frequency of and factors associated with quantitative coronary angiography (QCA)-defined longitudinal stent deformation (LSD) in various contemporary drug-eluting stents platforms. This study sought to evaluate the predictors of LSD and its long-term clinical implication. METHODS AND RESULTS: A patient-level pooled analysis was performed with 7350 lesions in 5871 patients treated with platinum-chromium-based everolimus-eluting stent (Promus Element), cobalt-chromium-based everolimus-eluting stent (Promus/Xience V), or cobalt-chromium-based zotarolimus-eluting stent (Endeavor Resolute)...

In some bifurcation anatomies side branch wiring can be difficult particularly when side branch is highly angulated. Furthermore a combination of bifurcations and chronic total occlusion can be a real challenge for interventional cardiologists. New devices have been produced to facilitate complex PCI and recently introduced dual lumen microcatheters can be really helpful in these scenarios. All these devices have both a rapid-exchange and an over-the-wire lumen. The rationale for dual lumen microcatheters is to preserve the highest number of side-branches...

PURPOSE: Although latissimus dorsi (LD) flaps are extensively used in a wide range of interventions, fetus studies on this subject are quite limited. This study aims to obtain detailed information about the morphometric features of LD, thoracodorsal artery (TDA) and nerve (TDN). METHODS: The study was carried out on both sides of 50 formalin-fixed human fetuses (22 male/28 female) with a mean gestational age of 24.5 ± 4.7 (range 18-36) weeks, which were in the inventory of Anatomy Department of Mersin University Faculty of Medicine...

Research has shown that gang membership increases the chances of offending, antisocial behaviour and drug use. Gang membership should be acknowledged as part of crime prevention and policy designs, and when developing interventions and preventative programmes. Correctional services are designed to rehabilitate convicted offenders. We formulate a deterministic mathematical model using nonlinear ordinary differential equations to investigate the role of correctional services on the dynamics of gangs. The recruitment into gang membership is assumed to happen through an imitation process...

The ultimate goal of the present work is to aid in the development of tools to assist in the treatment of cardiovascular disease. Gaining an understanding of hemodynamic parameters for medical implants allow clinicians to have some patient-specific proposals for intervention planning. In the present work an experimental and digital computational fluid dynamics (CFD) arterial model consisting of a number of major arteries (aorta, carotid bifurcation, cranial, femoral, jejunal, and subclavian arteries) were fabricated to study: (1) the effects of local hemodynamics (flow parameters) on global hemodynamics (2) the effects of transition from bedrest to upright position (postural change) on hemodynamics, and (3) diffusion of dye (medical drug diffusion simulation) in the arterial system via experimental and numerical techniques...

Percutaneous coronary intervention for bifurcated anatomy, particularly at the proximal left coronary artery site, requires guide catheters (GC) of at least 6 french and preferably larger in diameter. We describe a new trans-radial approach more suitable for small artery size: the simultaneous use of both radial arteries for double cannulation of the LMCA with 5F GC: each GC will target either the LM/LAD or the LM/CX artery (or LM-LAD/LM-LAD-1st diagonal branch) stenoses. The technique successfully was applied to 5 cases...

Background/Aims: Compared with metallic drug-eluting stents (DES), bioresorbable vascular scaffolds (BVS) may further improve long-term outcomes of percutaneous coronary intervention (PCI) in patients with coronary artery disease. We report our early experience with BVS in Korea. Methods: We evaluated 105 consecutive patients with BVS implanted at Asan Medical Center, Korea between October 21, 2015 and June 3, 2016. Angiographic results, and in-hospital and 6-month clinical outcomes were assessed...

BACKGROUND: Provisional stenting (PS) is the most common technique used to treat distal left main (LM) bifurcation lesions in patients with unprotected LM coronary artery disease undergoing percutaneous coronary intervention. The double kissing (DK) crush planned 2-stent technique has been shown to improve clinical outcomes in non-LM bifurcations compared with PS, and in LM bifurcations compared with culotte stenting, but has never been compared with PS in LM bifurcation lesions. OBJECTIVES: The authors sought to determine whether a planned DK crush 2-stent technique is superior to PS for patients with true distal LM bifurcation lesions...

INTRODUCTION: Non-traumatic biliary perforation other than the gallbladder is extremely rare and most commonly seen in children in association with congenital biliary anomalies. We present a rare case of choledocholithiasis that progressed to spontaneous perforation of the common hepatic duct probably from ischemic necrosis caused by impaction of large biliary stones. CASEREPORT: A 62-year-old female presented with diarrhea and jaundice. She was found to have two 2...

In the present paper, we investigate the dynamics of a model in which the real part of the economy, described within a multiplier-accelerator framework, interacts with a financial market with heterogeneous speculators, in order to study the channels through which the two sectors influence each other. Employing analytical and numerical tools, we investigate stability conditions as well as bifurcations and possible periodic, quasi-periodic, and chaotic dynamics, enlightening how the degree of market interaction, together with the accelerator parameter and the intervention of the fiscal authority, may affect the business cycle and the course of the financial market...

Two cats (2.5 months and 8 months old) were each evaluated due to a loud systolic murmur, and each was diagnosed with severe pulmonary artery stenosis at the bifurcation of the main pulmonary artery. Echocardiograms confirmed significant right atrial dilation and right ventricular dilation and/or hypertrophy that was progressive in one cat. Atenolol was initiated and the cats were referred for interventional therapy. Balloon angioplasty was performed via the jugular vein. In case 1, the pressure gradient across the stenosis was reduced from 169...

BACKGROUND: Although bifurcation percutaneous coronary intervention (PCI) is associated with lower procedural success rates and higher risk of complications, there are little data regarding outcomes after successful bifurcation PCI with contemporary stents and techniques. Whether residual platelet reactivity (PR) affects outcomes differently after bifurcation versus non-bifurcation PCI is also unknown. We studied the association between bifurcation PCI, PR, and clinical outcomes among patients undergoing successful PCI with drug-eluting stents...

BACKGROUND: Subjects undergoing coronary stenting with complex lesion anatomy may experience different risks and benefits with prolonged dual antiplatelet therapy. OBJECTIVES: The authors assessed the effect of 30 months versus 12 months of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) based on the presence or absence of anatomically-complex target lesions. METHODS: In the DAPT Study, combined myocardial infarction (MI) or stent thrombosis and moderate/severe bleeding were assessed in enrolled (n = 25,416) and randomized (n = 11,554) subjects...

The European Bifurcation Club (EBC) was initiated in 2004, to support a continuously overview of the field of coronary artery bifurcation interventions and aims to facilitate a scientific discussion and an exchange of ideas on management of bifurcation disease. EBC hosts an annual, two days compact meeting, dedicated to bifurcations, which brings together physicians, pathologists, engineers, biologists, physicists, mathematicians, epidemiologists and statisticians for detailed discussions. Every meeting is finalized with a consensus statement that reflects the unique opportunity of combining the opinion of interventional cardiologists with the opinion of a large variety of other scientists on bifurcation management...

We investigated the effect of low-density lipoprotein cholesterol (LDL-C) on the geometry of coronary bifurcation lesions. A total of 300 non-left main bifurcation lesions in 298 patients from J-REVERSE registry were classified according to statin treatment status at admission (NT, non-treated; ST, statin-treated) and were further subdivided based on LDL-C levels with a cutoff of 100 mg/dL (NT-high, n = 76 lesions; NT-low, n = 46; ST-high, n = 99 and ST-low, n = 79). In addition, a group with strict control of LDL-C (< 70 mg/dL) was defined (ST-SC; n = 19)...

Percutaneous coronary intervention (PCI) of lesions at coronary bifurcations poses a technical challenge. Short-term complications, including periprocedural myocardial infarction, and long-term complications such as in-stent restenosis and stent thrombosis, are higher in patients with bifurcation lesions. Techniques for PCI of bifurcation lesions include stenting of the main branch alone, and the use of two or more stents to cover the main and side branches. Two- or three-stent techniques include T-stenting, crush, culotte, simultaneous kissing stents, V-stenting, and Y-stenting...

BACKGROUND: This study sought to investigate the optimal percutaneous coronary intervention (PCI) strategy for true unprotected left main coronary artery (ULMCA) bifurcations. METHODS: The FAILS-2 was a retrospective multi-center study including patients with ULMCA disease treated with second-generation drug-eluting stents. Of these, we compared clinical outcomes of a provisional strategy (PS; n=216) versus an elective two-stent strategy (E2S; n=161) for true ULMCA bifurcations...

This study tested the complex relationship among the perceived benefit from and cost of condom use, self-efficacy and condom use among adolescents as a nonlinear dynamic process. Participants were 12th graders in public Bahamian high schools who reported having had sex and frequency of condom use. Results revealed that the perceived benefit and perceived cost as asymmetry variables were significantly associated with condom use (p < 0.001) after controlling for covariates. The association was bifurcated by the variable self-efficacy (p < 0...
