Sometimes little things can create big problems, which seems to be the case with the recall of the power unit used with the Abbott Heartmate 3 left ventricular assist device (LVAD). According to the FDA recall announcement, the power cords used with the power supply might not stay fixed in place, which would leave the power supply with 15 minutes of backup battery runtime before depletion.
The long-term use of ventricular assist devices is becoming a problem for at least some of these devices, as demonstrated by the recall of the Heartmate II and Heartmate 3 devices by Abbott Laboratories’ Abbott Vascular division due to obstruction of the outflow graft used to attach the device to the human heart.
Medtronic plc is ceasing global sales and distribution of its Heartware ventricular assist device (HVAD) due to safety concerns. The news sent Medtronic shares down about 1% in early morning trading. The Dublin-based company said it made the decision to stop selling the HVAD left ventricular assist device after clinical comparisons found a higher frequency of neurological adverse events, including stroke and mortality, with its heart pump device vs. other circulatory support systems.
In the latest step toward making left ventricular assist devices (LVADs) easier and more accessible, the FDA recently approved a less invasive surgical approach for use with Abbott Laboratories’ latest LVAD, Heartmate 3. Now, rather than requiring risky open-heart surgery, the device can be implanted through an incision in the chest wall. Abbott gained Heartmate 3 in its 2017 acquisition of St. Jude Medical for $25 billion.
