Summary
Severe tricuspid regurgitation poses a risk for right ventricular failure after left ventricular assist device implantation. A modified technique using a ventricular assist device ring simplifies future right ventricular support if needed.
Area of Science:
- Cardiovascular Surgery
- Mechanical Circulatory Support
Background:
- Severe tricuspid regurgitation is a risk factor for right ventricular failure post-left ventricular assist device (LVAD) implantation.
- Tricuspid valve repair (TVR) is often performed concurrently with LVAD implantation.
- The surgical approach for TVR can complicate subsequent right ventricular assist device (RVAD) implantation if needed.
Observation:
- A patient requiring LVAD implantation also had severe tricuspid regurgitation.
- The patient was on Impella and extracorporeal life support prior to LVAD implantation.
- A concomitant TVR was planned during the LVAD procedure.
Findings:
- A novel technique for right atrium closure after TVR was developed.
- A modified ventricular assist device ring was utilized for closure.
- This technique facilitates potential future RVAD implantation.
Implications:
- This method may streamline the process for patients requiring future right ventricular support.
- It addresses a potential complication in LVAD recipients with severe tricuspid regurgitation.
- Offers a potential solution for managing right ventricular failure in complex cardiac cases.
