Simple Felt-Plug Closure Technique for Minimally Invasive Removal of a Centrifugal-Flow Left Ventricular Assist...

Area of Science:

• Cardiovascular Surgery
• Biomedical Engineering
• Regenerative Medicine

Background:

• Left ventricular assist devices (LVADs) are increasingly used, with some patients achieving myocardial recovery and becoming candidates for device explantation.
• Standardized explantation procedures, particularly for newer centrifugal-flow devices, are lacking.
• A critical need exists for a method to seal the apical ventriculotomy site after centrifugal-flow LVAD removal.

Observation:

• Current centrifugal-flow LVADs necessitate a reliable method for sealing the apical ventriculotomy post-explantation.
• No commercially available sealing plugs are approved in the United States for this purpose.
• A novel technique was developed to create a custom plug for device removal.

Findings:

• A 33-year-old woman underwent minimally invasive explantation of a current-generation centrifugal-flow LVAD.
• A plug fashioned from Teflon felt and a Dacron graft was successfully used to seal the apical ventriculotomy.
• This technique facilitated a minimally invasive approach to LVAD explantation.

Implications:

• This novel technique offers a potential solution for the absence of commercial apical sealing plugs for centrifugal-flow LVADs.
• It enables minimally invasive explantation, potentially reducing patient morbidity.
• Further research and validation could lead to standardized procedures for LVAD explantation after myocardial recovery.
