Life-saving devices reach the end of life with heart failure

The Fountain of Youth Will Not Last Forever: End of Life in Patients Receiving Mechanical Circulatory Support

Health care providers face a unique set of decision-making, assessment, and equipment challenges at the end of life of patients supported with a left ventricular assist device. The aim for this article is to assist the multidisciplinary team in caring for patients with a left ventricular assist device in all phases of end-of-life care. This review includes common causes of death for patients with a left ventricular assist device, assessment at end of life, physiological and palliative care considerations, withdrawal of left ventricular assist device support, and equipment considerations.

Managing Implantable Cardioverter-Defibrillators at End-of-Life: Practical Challenges and Care Considerations

Implantable cardioverter-defibrillators (ICDs) monitor for and terminate malignant arrhythmias. Given their potential as a life-saving therapy, an increasing number of people receive an ICD every year, and a growing number are currently living with ICDs. However, cardiopulmonary arrest serves as the final common pathway of natural death, and the appropriate management of an ICD near the end-of-life is crucial to ensure that a patient's death is not marked by further suffering due to ICD shocks. The tenets of palliative care at the end-of-life include addressing any medical intervention that may preclude dying with dignity; thus, management of ICDs during this phase is necessary. Internists are at the forefront of discussions about end-of-life care, and are likely to find discussions about ICD care at the end-of-life particularly challenging. The present review addresses issues pertaining to ICDs near the end of a patient's life and their potential impact on dying patients and their families. A multidisciplinary, patient-centered approach can ensure that patients receive the maximum benefit from ICDs, without any unintended pain or suffering.

Planning for Deactivation of Implantable Cardioverter Defibrillators at the End of Life in Patients With Heart Failure

Implantable cardioverter defibrillators (ICDs) may be burdensome in end-stage heart failure. At the end of life, as many as one-fifth to one-third of patients experience an ICD shock. Critical care nurses should be aware of the potential burden of these shocks at the end of life as well as the ethics and organizational policies surrounding ICD deactivation. This literature review examines the issues surrounding ICD therapy at the end of life. Based on this author's findings, recommendations for discussing and implementing ICD deactivation are offered. Health care organizations should have clear policies addressing ICD deactivation to provide for seamless integration of palliative care services throughout the course of heart failure. These policies should empower nurses to activate resources in a timely manner and should clearly outline processes for ICD deactivation.

Rise of the Machines: In an Era of Ventricular Assist Devices, Prolonging Life or Death?

The past few decades witnessed the unprecedented "rise of the machines"; life-prolonging devices to support failing organs or as a form of organ replacement. Sophisticated machines provide us clinical milieu to intervene on sicker, dying patients, support the failing organ, prevent downward trajectory to multi-organ failure, and avert death. Hemodialysis has been in existence for several decades and has become the standard therapy for acute renal failure. Extracorporeal liver assist device replaces the detoxification function of the failing liver. Extracorporeal membrane oxygenator in cases of profound respiratory failure can replace the native lung function in the oxygenation of the venous blood and removal of carbon dioxide. The technology can also be used as a short-term heart-lung machine to keep the patient alive in the event of profound refractory cardiopulmonary collapse until the native heart and lung function returns. Ventricular assist devices (VADs) can completely replace the cardiac function in patients with end-stage heart failure and provide systemic flow. These innovative machines were developed under the assumption that they will improve survival, functional capacity, and quality of life in this cohort of patients. This case study focuses on the appropriate use of VADs as an alternative therapy for end-stage heart failure. This will explicate the ethical dilemma that concomitantly may arise with the use of these sophisticated organ replacement strategies when the goals of their placement are not met and just merely prolonging the dying process.
