TR, trivial PI, and multiple homogenous masses in the LV and right side of the heart as well as clot strands in the main pulmonary artery (MPA) (Figure 1C). Therefore, she underwent emergency cardiac surgery on the 3rd day and multiple thrombi were resected from the cardiac chambers with the repair of the tricuspid valve.
