Key Words: Intracardiac thrombi Cardiac defibrillator Intracardiac leads
Several years after an anterior wall infarction, a 62-year-old man experienced a cardiac arrest with successful resuscitation. An internal cardiac defibrillator was implanted. Five years later, echocardiography showed a large thrombus attached to the right ventricle lead (Figs. 1 and 2
). Thrombus removal, left ventricle remodeling, mitral and tricuspidal annuloplasty were successfully performed.
