The NeoChord DS1000 device for trans-apical beating-heart implantation of neo-chordae to the MV valve showed a high procedural success. A significant difference between an expert and beginner surgeon was detected, which emphasizes the importance of training before introduction of this new technique into clinical practice. Surgical workflow analysis proved to be a valuable tool to assess the performance of this new technique.
