Based on these promising results of efficiency, we can hypothesize that the active balloons in combination with the Excimer laser would improve the quality of life of patients while reducing the cost of their treatment, this compared to only assets balloons. This same improvement in quality of life with reduced costs of care would be observed for only assets compared to standard balloons. In health economic terms, it is therefore likely that the strategy combining assets balloons and Excimer laser is dominant over assets balloons themselves dominant over standard balloons.
