Permanent pacemaker implantation improves survival but can cause tricuspid valve dysfunction in the form of regurgitation (TR). The dominant mechanism pacemaker-mediated TR is lead impingement. This study evaluated association between location leads crossing and incidence worsening impingement using fluoroscopy. Lead positions were perpendicular right anterior oblique (RAO) parallel left (LAO) ...

Abstract The aim of this paper is to optimize turbine blade cooling channels by applying jet impingement Method. selection experiment data for NASA 3CX blade, and 3D model using solidworks software create computational fluid dynamics (CFD) simulations used the coolant flow temperature distribution in vane, while experimental testing can validate CFD results provide additional insights into syst...
