Withdrawal of ventricular assist device support

Area of Science:

• Cardiology
• Mechanical Circulatory Support
• Medical Ethics

Background:

• Advanced heart failure necessitates mechanical circulatory support with Ventricular Assist Devices (VADs).
• VADs offer treatment, not a cure, with significant mortality rates on device support.
• High mortality underscores the need for clear end-of-life care protocols.

Purpose of the Study:

• To describe the integration of device withdrawal processes within a VAD program.
• To analyze factors influencing device withdrawal discussions and decisions.
• To highlight the importance of structured protocols in VAD care.

Main Methods:

• Retrospective analysis of 22 VAD implantations from October 2001 to December 2004.
• Examination of 7 cases involving device withdrawal.
• Review of factors influencing withdrawal discussions, including family initiation and team disagreements.

Main Results:

• The average support duration before withdrawal was seven days.
• Family members initiated withdrawal discussions in 4 of 7 cases, particularly for elective bridge-to-transplantation cases.
• Disagreements arose between ICU and transplant teams regarding withdrawal timing and responsibility.

Conclusions:

• A formalized process for device withdrawal is integral to VAD program success.
• Pre-implantation preparation, disagreement resolution strategies, and clear withdrawal procedures are essential.
• Structured end-of-life care planning improves VAD program management.
