Abstract

Chiari network is a moving fibrous mesh-like structure that is visualized in 2% of cases in the right atrium. It is attached on one side to the valve of the inferior vena cava and on the other to different parts of the right atrium. In most cases this structure has no clinical significance and may be an accidental finding during echo- imaging. But sometimes it can be a source of thrombosis and in the future – the cause of thromboembolism, or, conversely, be an obstacle to the movement of thrombus.
