Related Articles A detailed fluid mechanics study of tilting disk mechanical Heart Valve closure and the implications to blood damage. J Biomech Eng. 2008 Aug;130(4):041001 Authors: Manning KB, Herbertson LH, Fontaine AA, Deutsch S Hemolysis and thrombosis are among the most detrimental effects associated with mechanical Heart valves. The strength and structure of the flows generated by the closure of mechanical Heart valves can be correlated with the extent of blood damage. In this in vitro study, a tilting disk mechanical Heart Valve has been modified to measure the flow created within the Valve housing during the closing phase. This is the first study to focus on the region just upstream of the mitral Valve occluder during this part of the cardiac cycle, where cavitation is known to occur and blood damage is most severe. Closure of the tilting disk Valve was studied in a "single shot" chamber driven by a pneumatic pump. Laser Doppler velocimetry was used to measure all three velocity components over a 30 ms period encompassing the initial Valve impact and rebound. An acrylic window placed in the housing enabled us to make flow measurements as close as 200 microm away from the closed occluder. Velocity profiles reveal the development of an atrial vortex on the major orifice side of the Valve shed off the tip of the leaflet. The vortex strength makes this region susceptible to cavitation. Mean and maximum axial velocities as high as ...

J Am Soc Echocardiogr. 2008 Oct 3; Authors: Kutty S, Deatsman SL, Russell D, Nugent ML, Simpson PM, Frommelt PC BACKGROUND: This study evaluated regional right ventricular (RV) mechanics before and after pulmonary Valve replacement (PVR) by ultrasonic speckle tracking technology using velocity vector imaging (VVI). METHODS: Fifty-eight patients who underwent PVR (May 1999 to August 2007) were included. Two-dimensional Doppler indices included qualitative pulmonary incompetence, RV outflow tract peak gradient, RV systolic pressure estimate, indexed RV area, and fractional area change; VVI regional indices included peak systolic and diastolic velocities, peak systolic strain, maximal longitudinal displacement, and times to peak measure from 6 RV segments. RESULTS: PVR was performed at a median age of 12.1 years with echocardiographic analysis at median intervals of 2.8 months before and 30 months after PVR. Peak velocities and displacement increased in all 6 RV segments after PVR; peak systolic strain did not improve consistently. All indices remained significantly lower compared with normal values. There was a significant decrease in the degree of pulmonary incompetence, RV outflow tract gradient, RV systolic pressure, and indexed RV area ...

Most PS3 owners probably know by now that Valve isn't exactly 'fond' of the PS3. The company has publicly spoken out against the console on many occasions. They've even gone so far as to purposely stay away from developing for the PS3. Last year's The Orange Box is one example, as it had to be ported by EA to even see release and most recently 'Left 4 Dead' was said to not be coming to the PS3. Well, it appears since that announcement, Valve has had a change of Heart. Doug Lombardi has told CVG that he has indeed changed his mind about the PS3, due to the console's success. As a company, they still prefer the PC and Xbox 360 over the PS3 but from a business standpoint, it only makes sense to start considering the PS3 as an option.  read more » ...
