A 52-year-old woman presented with malignant ventricular arrthythmogenesis intraoperatively during kyphoplasty for an osteoporotic fracture of a lumbar vertebra. No previous cardiovascular condition was known. Causes of arrhythmogenesis associated with the procedure were excluded. Due to her positive family history for dilated cardiomyopathy, upcoming thoughts were made for unmasking a previous asymptomatic cardiomyopathy. Nevertheless, an intracardiac cement embolism was diagnosed and, finally, the patient underwent an open heart surgery with successful removal of the cardiac cement while no new arrhythmogenic episode was recorded during follow up.
