Case in brief
A 68-year-old male with end-stage ischemic cardiomyopathy underwent left ventricular assist device (LVAD) implantation. Shortly after the procedure, his ECG displayed the 'Spiked Helmet Sign' alongside QTc prolongation. Echocardiography revealed a 6-mm localized pericardial hematoma. The patient was managed conservatively, leading to a successful outcome.
Diagnostic / clinical pearl
The 'Spiked Helmet Sign' on ECG following LVAD implantation may indicate localized pericardial hematoma and should prompt immediate echocardiography.
