Percutaneous Impella Mechanical Circulatory Support Delivery Using Intravascular Lithotripsy

Area of Science:

• Cardiovascular Interventions
• Medical Device Technology
• Peripheral Arterial Disease Management

Background:

• Peripheral arterial disease (PAD) poses challenges for cardiovascular device implantation.
• Transfemoral access for hemodynamic support devices like Impella can be difficult in PAD patients.
• Novel approaches are needed to facilitate device delivery in complex PAD cases.

Observation:

• Twelve patients with PAD underwent peripheral intravascular lithotripsy (IVL) before Impella device insertion.
• The study focused on the feasibility and safety of using IVL to prepare the arterial access site.
• Successful transfemoral access was the primary endpoint evaluated.

Findings:

• All twelve patients (100%) achieved successful Impella device implantation following IVL treatment.
• No complications related to the intravascular lithotripsy procedure were reported.
• IVL demonstrated its utility in facilitating arterial access for Impella delivery.

Implications:

• Intravascular lithotripsy is a viable strategy to enhance transfemoral access for Impella devices in PAD.
• This approach may broaden the applicability of hemodynamic support in complex PAD patients.
• Further research should explore long-term outcomes and cost-effectiveness.
