Graphical AbstractRead detailed figure descriptionThis figure displays two main sections: the left panel shows gross tissue samples, one for short-axis sections with vertical cuts, and the other for long-axis sections with a horizontal cut. Below are microscopic images: Congo red staining highlights reddish areas in the left image, and anti-TTR antibody staining reveals yellow structures in the right. Detection rates for wild-type ATTR are indicated, with 83% for short-axis and 54% for long-axis sections. There’s a scale bar of 1 cm for gross images and 100 µm for microscopic images.Display full size
