The Synergy Megatron stent confers enhanced axial and radial forces, which makes it an ideal choice for ostial and calcified lesions. However, in this case, the stent fractured. The mechanical stress due to severe calcification at the ostium, followed by a swinging segment, probably caused hinge effect and led to a stent fracture. The fluoroscopy and stent-enhancing techniques suggest and could confirm the diagnosis, but intracoronary imaging is mandatory for anatomy characterization in order to decide treatment and optimize the result.
