Patients needing second-time or "re-do" heart surgery have a new safer alternative. New findings show that an "off-pump" surgical procedure is performed safely and has improved outcomes for patients than traditional methods.
Due to a newly standardized approach and enhanced technology, doctors can perform this controversial surgery and eliminate the damaging effects of using a heart bypass machine. Off-pump surgery, also known as the "beating heart" method, is performed while the heart is still beating without foreign support, such as the heart-lung machine, used in cardiopulmonary bypasses.
99% of the 86 patients undergoing re-do surgery in this study had the procedure initiated off-pump, out of which five were later converted to using a heart-lung machine. There were no deaths of those five patients and 81 procedures were successfully completed without a bypass machine. Of the 6.7% predicted deaths based on past on-pump redo operations, use of the beating heart method in this study resulted in just 2.2% deaths.

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
