Abstract The world-wide impact of traumatic injury and associated hemorrhage on human health and well-being is significant. Methods to manage bleeding from sites within the torso, referred to as non-compressible torso hemorrhage (NCTH), remain largely limited to the use of conventional operative techniques. The overall mortality rate of patients with NCTH is approximately 50%. Studies from the wars in Afghanistan and Iraq have suggested that up to 80% of potentially survivable patients die as a result of uncontrolled exsanguinating hemorrhage. The commercially available resuscitative endovascular balloon occlusion of the aorta (REBOA) is a percutaneous device… More >

Abstract Background and objective: Chronic total occlusion (CTO) guidewire have been recently reported as an alternative to radiofrequency for perforating atretic pulmonary valve. Since procedure failures or perforation of the right ventricle still occurred with CTO, we tried to enhance the stability, steering, and pushability of the wire using a microcatheter in order to improve the safety and efficacy of the procedure.
Methods: We performed pulmonary valve perforation with CTO guidewire and microcatheter in five consecutive newborns with pulmonary atresia with intact ventricular septum (PA‐IVS) under fluoroscopic and echocardiographic control.
Results: The valve was easily perforated at the first… More >

Abstract Clinically significant patent ductus arteriosus (PDA) has been associated with signifi‐ cant morbidity in extremely low birth weight (ELBW) infants. Current management of ELBW infants with hemodynamically significant PDA includes supportive treatment, pharmacological therapy, and surgical ligation. All of these therapeutic options have their advantages and limitations. More recently, transcatheter PDA closure has been described as a viable option in this population. In this paper, we provide a compre‐ hensive review of this emerging procedure. More >

Abstract The three-dimensional flow of a gravity-driven continuous thin liquid film on substrates containing micro-scale features is modelled using the long-wave lubrication approximation, encompassing cases when surface topography is either engulfed by the film or extends all the way though it. The discrete analogue of the time-dependent governing equations is solved accurately using a purpose designed multigrid strategy incorporating both automatic error-controlled adaptive time stepping and local mesh refinement/de-refinement. Central to the overall approach is a Newton globally convergent algorithm which greatly simplifies the inclusion of further physics via the solution of additional equations of the More >
