During the past decade, a hybrid procedure has emerged and dramatically evolved as an alternative stage I palliation to the conventional Norwood procedure in neonates with hypoplastic left heart syndrome (HLHS). The hybrid approach avoids the need for cardiopulmonary bypass (CPB) utilizing stenting of the arterial duct and bilateral pulmonary artery banding. Cerebral and coronary perfusion pressure is maintained, and the pulmonary vasculature is protected from higher systemic pressure. Elimination of risks associated with CPB gains vital time to stabilize the patient and correct coexisting noncardiac anomalies and allows growth in preparation for the later stages of the Fontan pathway...

OBJECTIVE: To investigate the therapeutic effect of allopurinol treatment on acute coronary syndrome and to elucidate its possible mechanism. METHODS: Patients with acute coronary syndrome (n=100) were recruited as research subjects in our hospital. The patients were randomly divided into two groups (allopurinol group, n = 50) and control group, n= 50). These two groups were treated with conventional antiplatelet, anticoagulation and anti-ischemic therapy, while allopurinol was added to allopurinol group based on conventional treatment...

We present two cases with chronic total occlusion of the saphenous vein graft in two patients with a history of previous bypass surgery with unfavorable anatomic features for recanalization of the native coronary artery. In the first case, two dedicated attempts for recanalization of chronic total occlusion of the native artery failed and in the second case there was not an adequate visualization of the native vessel beyond the occlusion point, not even by contralateral injection. Excimer laser atherectomy was used in both cases as an adjuvant therapy during recanalization of the saphenous vein graft in combination with a distal protection device in order to reduce distal embolization...

Embolic protection devices were developed to reduce the risk of stroke during carotid artery stenting. The aim of this study was to test the capture efficiency of five embolic protection devices under reproducible in vitro conditions. The setup consisted of silicone tubes representing the vessel modeling round and oval cross sections. Spherical polystyrene particles (150 μm, COOH-coating) were used to simulate the plaque. The particles were inserted in a clean water circuit and either captured by the device or collected in a glass filter...

OBJECTIVE Coiling of wide-necked and complex bifurcation aneurysms frequently requires implantation of double stents in various configurations. T-stent-assisted coiling involves the nonoverlapping implantation of 2 stents to protect the daughter vessels of bifurcation and is followed by coiling of the aneurysm. The authors studied the feasibility, efficacy, and safety of the T-stent-assisted coiling procedure as well as the midterm angiographic/clinical outcomes of patients with wide-necked bifurcation intracranial aneurysms treated using this technique...

BACKGROUND: First-generation drug-eluting stents - such as the sirolimus-eluting stent (SES) and paclitaxel-eluting stent (PES) - have become attractive options for percutaneous coronary intervention (PCI) and are still widely used in Asia. However, the effect of East Asian ethnicity on their efficacy remains unclear. METHODS: Pubmed, EMBASE, and the Cochrane Central Register of Controlled Trials were searched for randomized controlled trials comparing the efficacy of the Cypher SES and Taxus PES...

We conducted this study to determine the risk of transmission of Q fever to health care workers (HCWs) during perioperative exposure to Coxiella burnetii-infected thoracic endovascular aneurysm stent graft. Pre-operative and 6-week post-operative phase I and II IgG Q fever antibody titers were determined in 14 staff members of an operation room. The room had a negative pressure and all the members of the surgical team wore either a fitted N-95 mask or a powered purified air respirator. Phase I and II IgG antibody titers were <1:16 for 11 of the 14 studied HCWs; 2 HCWs did not follow up at 6 weeks and 1 had a pre-exposure phase II IgG titer of 1:128 with no change 6 weeks later...

OBJECTIVE: Endovascular interventions of the common femoral (CFA) and deep (DFA) femoral arteries are becoming more common. However, there is very little published data for guidance. Our objective was to analyze practice patterns and outcomes from these interventions. METHODS: The Vascular Quality Initiative (2010-2015) was queried for all endovascular interventions of the CFA and DFA. Cases that were emergent or for acute limb ischemia were excluded. Those with isolated CFA with or without DFA treatment were analyzed...

BACKGROUND: Percutaneous coronary intervention (PCI) with early generation drug-eluting stent (eDES) implantation for ostial right coronary artery (RCA) lesions is challenging because of the frequent need for repeat revascularization. We compared mid-term clinical outcomes following eDES or new generation DES (nDES) implantation for ostial RCA lesions. METHODS: The study included 150 patients with ostial RCA lesions, 76 treated with eDES and 74 with nDES between January 2005 and September 2013...

PURPOSE: Implanted fiducial markers are often used in radiotherapy to facilitate accurate visualization and localization of tumors. Typically, such markers are used to aid daily patient positioning and to verify the target's position during treatment. These markers can also provide a wealth of information regarding tumor motion, yet determining their accurate position in thousands of images is often prohibitive. This work introduces a novel, automated method for identifying fiducial markers in planar x-ray imaging...

Gastric outlet obstruction (GOO) which can be caused by benign and malignant diseases often leads to a reduction in patient quality of life. Lately endoscopic ultrasonography (EUS)-guided gastroenterostomy (EUS-GE) has emerged. At the present time, there are three types of EUS-GE using lumen-apposing biflanged metal stents (LAMS), i.e., direct EUS-GE, assisted EUS-GE using retrieval/dilating balloon, single balloon overtube, nasobiliary drain and untraslim endoscope, and EUS-guided double balloon occluded gastrojejunostomy bypass (EPASS)...

REVIEW
Tiing Leong Ang, Anthony Yuen Bun Teoh
Endoscopic ultrasound (EUS)-guided drainage is now firmly established as the best option for drainage of walled-off pancreatic fluid collections (PFC). It has high clinical efficacy, similar to surgical and percutaneous approaches, but with lower morbidity and costs. It is superior to non-EUS guided approaches because even collections without endoluminal bulging can be successfully drained. Transmural drainage alone is sufficient for pseudocysts, but in the context of walled-off pancreatic necrosis (WON), adjunctive direct endoscopic necrosectomy (DEN) may be required...

OBJECTIVES: Endoscopic procedures are used as first-line treatment for bile leak after hepatobiliary surgery. Advances have been made in endoscopic techniques and devices, but few reports have described the effectiveness of endoscopic procedures and the management principles based on the severity of bile leak. We evaluated the effectiveness of an endoscopic procedure for the treatment of bile leak after hepatobiliary surgery. METHODS: Fifty-eight patients underwent an endoscopic procedure for suspected bile leak after hepatobiliary surgery; the presence of bile leak on endoscopic retrograde cholangiopancreatography (ERCP) was evaluated retrospectively...

OBJECTIVES: In recent years, knowledge concerning the mechanical properties of self-expandable metallic stents (SEMS) has increased. In a previous study, we defined traction force and traction momentum and reported that these characteristics are important for optimal stent deployment. However, traction force and traction momentum were represented as relative values and were not evaluated in various conditions. The purpose of this study was to measure traction force in various situations assumed during SEMS placement...

OBJECTIVE: Hyperperfusion syndrome (HPS) following carotid artery stenting (CAS) is a rare but serious complication. HPS is associated with preoperative hemodynamic impairment due to poor collateral flow and intraoperative cerebral ischemia. Filter-type embolic protection devices (EPDs) maintain anterograde carotid flow during CAS and somewhat prevent HPS. Early treatment of patients undergoing CAS and at risk for HPS is essential. Near-infrared spectroscopy (NIRS) allows non-invasive, real-time measurement of frontal lobe regional cerebral O2 saturation (TOI; tissue oxygenation index)...

Embolic Protection Devices (EPD's) are often used during Carotid Angioplasty and Stenting (CAS) to reduce procedural cerebral emboli. This manuscript seeks to present an overview of evidence on EPD's during CAS. There are three categories of EPD's: Distal Occlusion (DO-EPD), Filter (F-EPD) and Proximal Occlusion (PO-EPD). DO and F-EPD's have the disadvantage that the device has to be advanced through the stenosis, without protection and that the device may damage the distal internal carotid artery (ICA). F-EPD's have the advantage of maintaining antegrade flow throughout the procedure...

: Restenosis after angioplasty is a serious clinical problem that can result in re-occlusion of the coronary artery. Although current drug-eluting stents have proved to be more effective in reducing restenosis, they have drawbacks of inhibiting reendothelialization to promote thrombosis. New treatment options are in urgent need. We have shown that netrin-1, an axon-guiding protein, promotes angiogenesis and cardioprotection via production of nitric oxide (NO). The present study examined whether and how netrin-1 attenuates neointimal formation in a femoral wire injury model...

Immobilization of bioactive peptide sequences on CoCr surfaces is an effective route to improve endothelialization, which is of great interest for cardiovascular stents. In this work, we explored the effect of physical and covalent immoblization of RGDS, YIGSR and their equimolar combination peptides on endothelial cells (EC) and smooth muscle cell (SMC) adhesion and on thrombogenicity. We extensively investigated using RT-qPCR, the expression by ECs cultured on functionalised CoCr surfaces of different genes...
