Cover Story: Valvular heart disease is a significant cause of cardiovascular morbidity and mortality. Minimal invasive cardiac surgery aims to restore health while decreasing the burden of intervention for affected patients. In the present study, we describe the use of automated suturing technology to facilitate valve repair in the setting of tricuspid regurgitation. Furthermore, we compare this modified approach to the conventional surgical technique in a passive beating heart model. The isolated and combined procedure proved to be effective in our experimental setup, offering a promising solution for the future treatment of tricuspid valve disease. View this paper
