After dissection of right ventricle free-wall, the ICD lead was visible. The lead body adhered to the tricuspid valve leaflets, and the tip was fixed near the right ventricle apex (A). The fibrotic change in the right ventricular septum was assumed to be related to the mechanical irritation of the endocardium by the ICD lead. The lead tip was embedded by fibrotic encapsulation (B), which often renders the lead extraction challenging.
