Abstract

Cardiac resynchronization with defibrillator (CRT-D) malfunction can be due to various reasons, including wire injury, insulation break, battery problems, or patient factors. Undesired outcomes can be dramatically elevated in those settings, prompting early detection and proper troubleshooting. To diagnose, clinical correlation and device interrogation are vital. However, it is not uncommon to find general troubleshooting options insufficient, as highlighted in this case report. Here, we presented an unusual "head assembly separation," as the main reason for abnormal device parameters.

Keywords: CRT-D malfunction; ICD malfunction; header assembly separation; unprecedented cause.
