Left ventricular assist device (LVAD) placement is challenging in restrictive cardiomyopathy. A novel technique using a left atrial conduit for HeartMate 3 inflow proved feasible and effective in a patient with restrictive cardiomyopathy and pulmonary hypertension.
Area of Science:
- Cardiology
- Medical Devices
- Surgical Techniques
Background:
- Restrictive and hypertrophic cardiomyopathy pose challenges for left ventricular assist device (LVAD) implantation due to small left ventricle (LV) cavities.
- Previous studies have documented the use of expanded polytetrafluoroethylene (ePTFE) conduits for HeartWare HVAD inflow cannulation via the atrial septum into the left atrium.
