Stenting of the left pulmonary venous baffle obstruction was successfully performed in a 6 year old girl after the Mustard operation for transposition of the great arteries. She also had stent implantation in both the superior vena cava and inferior vena cava baffle junctions. These procedures were followed by sustained clinical improvement. Angiography showed that all three stents were fully p...

in this paper, the effects of baffle on thermal characteristics of combined convection-radiation heat transfer in laminar flow adjacent to an inclined backward facing step (bfs) in a horizontal duct are investigated. a baffle is mounted on the top wall of channel downstream side of step. in this study, the fluid is treated as a gray, absorbing, emitting and scattering medium; therefore, in the ...

A two-phase fluid flow model solving Navier-Stokes equations was employed in this paper to investigate liquid sloshing phenomena in cubic tank with horizontal baffle, perforated vertical baffle, and their combinatorial configurations under the harmonic motion excitation. Laboratory experiment of liquid sloshing in cubic tank with perforated vertical baffle was carried out to validate the presen...

In this paper, head baffle and head shadow effects were measured at a front-oriented and at a back-oriented microphone in a hearing aid casing when worn by human subjects and when placed on a dummy head. Some differences in head baffle and head shadow effects were observed for the front-and back-oriented microphones in that greater head baffle effects were observed at the front microphone than ...

BACKGROUND Factors associated with obstruction of the cavopulmonary pathway in patients with a lateral tunnel (LT) intracardiac Fontan connection and outcomes of percutaneous stent implantation for this complication have not been characterized. METHODS AND RESULTS Between 1999 and 2011, 51 patients underwent stent implantation for LT pathway stenosis at a median age of 10.2 years and a median...

Computational fluid dynamics simulations are employed to assess the effect of adding a vertical baffle at the feed section of a full-scale edimentation tank for the improvement of solids settling in potable water treatment. A general CFD-based simulation strategy is developed based n the specific features and conditions met in practice for potable water treatment. The linearity of the particle ...

In order to increase the performance of a primary sedimentation tank (clarifier), it is essential to have a uniform and calm flow field. The use of suitable baffle configurations may help forming favorable flow field and increase the efficiency of the primary sedimentation tank. In order to find the proper position of a baffle in a rectangular primary sedimentation tank, computational investiga...

A baffle puncture is a challenging procedure but can be safely done using direct visualization of the region of interest. To our knowledge, however, it has never been performed in a patient with dextrocardia. We present a 62-year-old male with dextrocardia, right isomerism, congenitally corrected transposition of the great arteries, persistent left-sided superior and inferior caval veins, atria...

This patient was seen for the first time at Children's Hospital of Pittsburgh at 34 days of age with cyanosis and grunting respirations of two weeks duration. Cardiac catheterization and angiography confirmed the diagnosis of transposition of the great arteries (TGA) with an intact ventricular septum. Following balloon atrial septostomy, systemic arterial saturation rose to 80% from 34%. Repeat...
