Percutaneous Decommissioning of Left Ventricular Assist Device

Area of Science:

• Cardiology
• Mechanical Circulatory Support

Background:

• Left ventricular assist devices (LVADs) significantly improve outcomes for advanced heart failure patients.
• A subset of LVAD patients achieve myocardial recovery, enabling device weaning.
• Identifying suitable candidates and managing the weaning process present clinical challenges.

Observation:

• Minimalist surgical approaches for LVAD implantation and explantation aim to reduce cardiac trauma.
• A review of evolving explant strategies informed the decision-making process for LVAD weaning.
• Two out of 69 LVAD patients (2.9%) were successfully weaned between 2009 and 2014.

Findings:

• One patient underwent minimal access implantation of a HeartWare Ventricular Assist Device (HVAD).
• LVAD decommissioning was achieved non-surgically using a percutaneous Amplatzer Vascular Plug II device due to outflow graft thrombosis.
• This case highlights a novel, minimally invasive method for LVAD removal.

Implications:

• Minimalist LVAD explantation strategies may reduce morbidity associated with device removal.
• Non-surgical decommissioning techniques offer a less invasive alternative for LVAD removal in specific scenarios.
• Further research into patient selection and advanced weaning protocols is warranted to optimize LVAD bridge-to-recovery outcomes.
