Key result
Sub-muscular implantation of a cardiac device without anchoring resulted in device hypermobility and a subsequent mechanical stress-induced left ventricular lead fracture.
Why the study?
Lead fracture is a recognized mechanical complication of implanted cardiac devices.
Sub-muscular implantation of cardiac devices without anchoring may cause device hypermobility and subsequent lead fracture.
Alerts to lead fracture risk from unanchored sub-muscular device hypermobility; hypothesis-generating for anchoring strategies.
Lead fracture is one of the mechanical complications of implanted cardiac devices. We present a case of mechanical stress-induced left ventricular lead fracture attributed to the hypermobility of the device secondary to sub-muscular implantation of the device without anchoring it.
