Transaxillary Stenting of LVAD Outflow Graft Obstruction

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Medical Device Technology

Background:

• Left ventricular assist devices (LVADs) are crucial for end-stage heart failure management.
• Outflow graft obstruction is a serious LVAD complication, often requiring complex surgical revision.
• Redo sternotomy carries significant risks, especially in elderly patients.

Observation:

• An 82-year-old patient with a HeartMate II LVAD experienced cardiogenic shock due to outflow graft obstruction.
• The patient presented with critical low-flow alarms indicating device malfunction.
• High surgical risk precluded traditional redo sternotomy.

Findings:

• A percutaneous intervention using peripheral stents was successfully performed to address the LVAD outflow graft obstruction.
• This represents a novel, minimally invasive approach for managing LVAD complications.
• The procedure was technically challenging, classified at an advanced level of difficulty.

Implications:

• Percutaneous stenting offers a viable, lower-risk alternative to sternotomy for LVAD outflow graft obstruction.
• This case expands the interventional options for managing mechanical circulatory support device complications.
• Further research is warranted to establish the long-term efficacy and safety of this technique.
