Reactive cholecystitis as the leading sign of subacute perforation of the right ventricle with the electrode of an implantable cardioverter defibrillator

Subacute lead perforation of the right ventricle caused acute, reactive, acalculous cholecystis, which initially distracted the attention of physicians from the development of hematopericard. Implantation of a cardioverter defibrillator in a young patient after sudden cardiac arrest, but before treatment of significant stenosis of the proximal left anterior descending artery, resulted in a life-threatening condition only 36 days after arrest. After removing the implantable cardioverter defibrillator, there was no sign of pathological cardiac rhythm disorders.
