In AL amyloidosis, fibrils accumulate in the heart, where they are exposed to shear stress. To mimic cardiac amyloidosis, where each heartbeat causes diameter fluctuations in coronary arterioles, we employ a peristaltic pump using the same mechanical principle to induce shear stress, combined with thioflavin T fluorescence microscopy for\n                    <jats:italic>in situ<\/jats:italic>\n                    real\u2010time observation of amyloid formation of an AL protein associated with heart amyloidosis. Our results demonstrate that confined geometries amplify shear stress\u2013dependent amyloid nucleation. Furthermore, using grid\u2010type microchannels to model arteriole networks under shear stress, we observed fluorescent amyloid bursts reflecting dynamic pathways shaped by fibril deposition, local mechanical stress, and channel occlusion. We also observed that mechanical agitation using a micromanipulator, in conjunction with disaggregating agents, was effective for removing amyloid deposits. Collectively, our findings reveal key principles underlying shear stress\u2013dependent amyloid formation and provide a novel framework for understanding amyloid deposition in organs, potentially advancing anti\u2010amyloidosis strategies.\n
