Longest Ongoing Support (13 Years) with Magnetically Levitated Left Ventricular Assist Device

Area of Science:

• Cardiology
• Biomedical Engineering
• Mechanical Circulatory Support

Background:

• Left ventricular assist devices (LVADs) are crucial for end-stage heart failure management.
• Uncertainty exists regarding the maximum service life of LVADs due to patient outcomes like transplantation or mortality before device exhaustion.
• The Incor LVAD (Berlin Heart) was produced between 2002 and 2018.

Observation:

• A 65-year-old patient received an Incor LVAD 13 years ago.
• This represents the longest published and ongoing LVAD support case to date.
• The patient experienced driveline damage necessitating a pump exchange.

Findings:

• The patient has been supported by an Incor LVAD for 13 years, a duration exceeding typical device longevity assessments.
• Following a pump exchange due to driveline issues, the patient was discharged and continues LVAD support.
• This case highlights the potential for extended functional longevity of LVADs beyond initial estimations.

Implications:

• This case suggests that current LVADs may offer longer support than previously assumed, challenging existing longevity paradigms.
• Extended LVAD support can provide a viable long-term therapeutic option for carefully selected heart failure patients.
• Further research into device durability and long-term patient management is warranted to optimize mechanical circulatory support strategies.
