A novel technique to exclude the left ventricle with an assist device
Insights
Left ventricular assist devices (LVADs) can cause blood clots. A new cone-shaped prosthesis completely excludes the left ventricle, potentially reducing thrombosis risk around the LVAD inflow cannula.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
- Medical Device Design
Background:
- Left ventricular assist device (LVAD) implantation alters intracardiac blood flow.
- Altered flow patterns are associated with thrombosis risk, particularly near the inflow cannula.
- Current LVAD techniques may not fully optimize intracardiac hemodynamics.
Abstract:
Left ventricular assist device implantation disrupts the natural intracavitary blood flow path through the heart, introducing flow patterns potentially associated with thrombosis, especially around the inflow cannula. We describe a novel technique for completely excluding the left ventricle with an assist device by using a cone shaped ring-reinforced prosthesis.
