Long-term outcomes of percutaneous tricuspid annuloplasty with Cardioband device.

Aims: Severe tricuspid regurgitation (TR) has adverse effects on outcomes, with limited therapeutic options. We report the outcomes of patients undergoing percutaneous annuloplasty as a treatment of  ≥severe functional TR in a single centre.

Methods And Results: Prospective, single-arm, single-centre study that enrolled 24 consecutive patients with at least severe functional TR undergoing percutaneous annuloplasty with Cardioband system between 2019 and 2021.

Quantification of HO by H-MR imaging at 3 T: a feasibility study.

Background: Indirect H-magnetic resonance (MR) imaging of O-labelled water allows imaging in vivo dynamic changes in water compartmentalisation. Our aim was to describe the feasibility of indirect H-MR methods to evaluate the effect of HO on the MR relaxation rates by using conventional a 3-T equipment and voxel-wise relaxation rates.

Methods: MR images were used to calculate the R1, R2, and R2* relaxation rates in phantoms (19 vials with different HO concentrations, ranging from 0.

Secure and secret cooperation in robot swarms.

The importance of swarm robotics systems in both academic research and real-world applications is steadily increasing. However, to reach widespread adoption, new models that ensure the secure cooperation of large groups of robots need to be developed. This work introduces a method to encapsulate cooperative robotic missions in an authenticated data structure known as a Merkle tree.
