Discontinuation of Cardiac Devices at or Near an Adult Patient’s End of Life

Advances in medical technology have begun to blur the lines between life and death as well as the lines between appropriate and inappropriate therapy. This review addresses the charged issue of the management of cardiac devices at or near the end of a patient's life, provides a summary of prior and current opinion with some historical context, and attempts to provide some modest guidance as to how to approach the various options to the patient's best advantage. Modalities to be addressed include indwelling electronic devices, the left ventricular assistance device, and extracorporeal mechanical oxygenation, and includes available outcome data as well as ethical analysis from a number of commentators. The expected further increase in technical sophistication of these devices is expected to render the various aspects of device deactivation more and more complex over the course of the next few years such that careful attention to and knowledge about this issue will continue to be more and more necessary.
