Interventricular septal hematoma is a rare complication of retrograde chronic total occlusion (CTO) percutaneous coronary interventions (PCI) with a typically benign course. Here we report two cases of interventricular septal hematoma and coronary-cameral fistula development after right coronary artery (RCA) CTO-PCI using a retrograde approach. Both were complicated by development of ST-segment elevation and chest pain. One case was managed actively and the other conservatively, both with a favorable outcome...

PURPOSE: The purpose of this study was to compare the reliability of ultrasound-based shear wave elastography in regions of homogeneous versus heterogeneous elasticity by using two different probes. METHODS: Using acoustic radiation force impulse (ARFI) elastography, we measured the shear wave velocity (SWV) in different lesions of an elastography phantom with the convex 4C1 probe and the linear 9L4 probe. The region of interest (ROI) was positioned in such a way that it was partly filled by one of the lesions (0%, 25%, 50%, 75%, and 100%) and partly by the background of the phantom (100%, 75%, 50%, 25%, and 0%, respectively)...

The primate gastrointestinal tract is home to trillions of bacteria, whose composition is associated with numerous metabolic, autoimmune, and infectious human diseases. Although there is increasing evidence that modern and Westernized societies are associated with dramatic loss of natural human gut microbiome diversity, the causes and consequences of such loss are challenging to study. Here we use nonhuman primates (NHPs) as a model system for studying the effects of emigration and lifestyle disruption on the human gut microbiome...

Arteria Lusoria or aberrant right subclavian artery (ARSA) is present in 0.6-1.4% of individuals. It typically remains clinically silent and is often discovered during angiographic procedures. The presence of ARSA can make a right transradial approach for coronary angiography and angioplasty technically more difficult. With the use of catheter support, we describe two cases in which a right transradial approach for catheterization was successful in the setting of ARSA. As such, the presence of ARSA does not warrant abandoning a transradial approach for coronary angiography and angioplasty...

Chronic total occlusion (CTO) revascularization is traditionally limited by the challenges related to lesion crossing. In a smaller number of cases, however, inability to advance the balloon catheter to the crossing site can account for recanalization failure ("balloon uncrossable" CTO). We describe a case of a "balloon uncrossable" CTO in which balloon crossing was achieved after subintimal dilation and "external crushing" of the CTO lesion resulting in significant modification of the CTO atheromatous plaque...

The effects of shear and particle shape on the physical adsorption of a polymer (polyvinyl pyrrolidone, PVP) on carbon nanoparticles (CNPs) were studied with dissipative particle dynamics (DPD) methods. It was found that the conformation of the polymer during adsorption and desorption from the nanoparticle can be classified into three possible types, i.e. adsorbed, shear-affected and separated, depending on the magnitude of the shear rate in the flow. Spherical and graphene sheet-shaped particles with adsorbed PVP were manipulated in a Couette flow to determine the threshold shear rates leading to changes in the polymer adsorption state...

BACKGROUND: Primary health care facilities frequently manage dengue cases on an ambulatory basis for the duration of the patient's illness. There is a great opportunity for specific messaging, aimed to reduce dengue virus (DENV) transmission in and around the home, to be directly targeted toward this high-risk ambulatory patient group, as part of an integrated approach to dengue management. The extent however, to which physicians understand, and can themselves effectively communicate strategies to stop focal DENV transmission around an ambulatory dengue case is unknown; the matter of patient comprehension and recollection then ensues...

Dissipative particle dynamics (DPD) simulations were utilized to investigate the ability of sodium dodecyl sulfate (SDS) to adsorb inside a single-walled, arm-chair carbon nanotube (SWCNT), as well as the effect of surfactant on the properties of water inside the SWCNT. The diameter of the SWCNT varied from 1 to 5 nm. The radial and axial density profiles of water inside the SWCNTs were computed and compared with published molecular dynamics results. The average residence time and diffusivity were also calculated to show the size effect on mobility of water inside the SWCNT...

BACKGROUND: After successful guidewire passage, failure to cross the occluded segment with a balloon is the most common cause of procedural failure in coronary chronic total occlusion (CTO) intervention. We evaluated the safety and efficacy of the balloon-assisted microdissection (BAM) technique for treating these complex balloon-uncrossable lesions. METHODS: We identified consecutive cases treated with BAM for balloon-uncrossable CTOs between January 2012 and February 2015 at two experienced CTO percutaneous coronary intervention (PCI) centers and reviewed their clinical and angiographic characteristics and procedural outcomes...

Objective. Out of hospital cardiac arrest (OHCA) patients are a critically ill patient population with high mortality. Combining mild therapeutic hypothermia (MTH) with early coronary intervention may improve outcomes in this population. The aim of this study was to evaluate predictors of mortality in OHCA patients undergoing MTH with and without cardiac catheterization. Design. A retrospective cohort of OHCA patients who underwent MTH with catheterization (MTH + C) and without catheterization (MTH + NC) between 2006 and 2011 was analyzed at a single tertiary care centre...

Inability to cross the occlusion with a guidewire is the most common cause of failure of coronary chronic total occlusion (CTO) interventions. We describe two cases of successful application of the novel Gaia family of coronary guidewires (Asahi Intecc) for crossing coronary CTOs using all available crossing strategies, namely antegrade wire escalation, antegrade dissection/reentry, and retrograde.

Active illumination based methods have a trade-off between acquisition time and resolution of the estimated 3D shapes. Multi-shot approaches can generate dense reconstructions but require stationary scenes. Single-shot methods are applicable to dynamic objects but can only estimate sparse reconstructions and are sensitive to surface texture. We present a single-shot approach to produce dense shape reconstructions of highly textured objects illuminated by one or more projectors. The key to our approach is an image decomposition scheme that can recover the illumination image of different projectors and the texture images of the scene from their mixed appearances...

Despite the increasing popularity of the Ponseti method for the treatment of idiopathic congenital clubfeet, the relapse rate and sequela after the initial correction of manipulating and casting remain high. This study presents a scale to evaluate the relapse and identify the factors correlated with the relapse and latest follow-up mid-term results. A total of 101 children (newborn to 12 months), 142 idiopathic congenital clubfeet, were recruited for this study following treatment with the Ponseti method at the Hospital for Traumatology and Orthopaedics (Ho Chi Minh City, Vietnam) with a follow-up period of a minimum of 2 years...

A total of 34 highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) strains isolated from Vietnam during 2013-2014 were sequenced and analyzed. A partial sequence of ORF1a corresponding to the nonstructural protein 2 (Nsp2) coding region and the full sequence of open reading frame 5 (ORF5) gene was used for the analysis. The HP-PRRSV strains were isolated from pig herds that had never been vaccinated for PRRSV. Nucleotide sequence identities in the portions of ORF1a corresponding to the nonstructural protein 2 (Nsp2) coding region and ORF5 ranged from 96...

We present a case of left isomerism with total anomalous systemic venous connection where the inferior vena cava was absent and all other systemic veins connected abnormally to the left atrium. The right atrium was hypoplastic with an intact atrial septum. Blood flow to the lungs was through a large ventricular septal defect. The diagnosis was made with echocardiography, angiography, and computed tomography. Complete repair was performed successfully, and the 7-year-old patient had an uneventful recovery.
