Long-Term Survival in Patients Receiving a Continuous-Flow Left Ventricular Assist Device

Area of Science:

• Cardiology
• Medical Devices
• Heart Failure Management

Background:

• Increasing prevalence of long-term survivors with left ventricular assist devices (LVADs).
• Need to characterize outcomes for patients exceeding four years on LVAD support.

Purpose of the Study:

• To describe characteristics and outcomes of patients surviving longer than 4 years on LVAD support.
• To evaluate long-term efficacy and safety of continuous-flow LVADs (CF-LVADs).

Main Methods:

• Multicenter, retrospective analysis.
• Included patients with HeartMate II CF-LVAD support surviving at least 4 years.
• Data collected from centers in the Evolving Mechanical support Research Group.

Main Results:

• 156 long-term survivors identified, with a mean survival of 7.1 years.
• Low readmission rate (1.1 events/patient/year), primarily due to infection and GI bleeding.
• Sustained functional improvement: 97% NYHA class I/II at 2 years, 92% at 4 years.

Conclusions:

• Patients surviving 4 years on CF-LVAD support demonstrate ongoing long-term survival.
• Sustained improvements in functionality are expected.
• Low rates of rehospitalization are maintained beyond 4 years.
