Left atrium is not a passive heart chamber, because it has a dynamic motion respecting heart cycle and, in accordance with its stretching, it releases atrial natriuretic peptides. Since in the course of certain invasive procedures the size of left atrium may change substantially, its exact measurement and functional characterization are essential. The aim of the present review is to summarize echocardiographic methods for the assessment of left atrial size and functional parameters. Orv. Hetil., 2014. 155(41), 1624–1631.

Laser aided Directed Material Deposition (DMD) is an additive manufacturing process based on laser cladding. A full understanding of laser cladding is essential in order to achieve a steady state and robust DMD process. A two dimensional mathematical model of laser cladding with droplet injection was developed to understand the influence of fluid flow on the mixing, dilution depth, and deposition dimension, while incorporating melting, solidification, and evaporation phenomena. The fluid flow in the melt pool that is driven by thermal capillary convection and an energy balance at the liquid–vapor and the solid–liquid interface was investigated and the impact of the droplets on the melt pool shape and ripple was also studied. Dynamic motion, development of melt pool and the formation of cladding layer were simulated. The simulated results for average surface roughness were compared with the experimental data and showed a comparable trend.
