Purpose: In order to facilitate anastomoses during beating
heart surgery, right ventricular assist devices (RVAD) were developed.
We would like to present our first experiences with two RVAD systems.
Material and methods: The use of two RVAD system (ENABLER
and IMPELLA). was attempted in 17 patients:
Results: ENABLER group: Out of 5 patients, the device
worked well in 2 patients, but could not be positioned in the
pulmonary artery (PA) in 3 patients, accompanied by blood loss
from the insertion site and ventricular fibrillation (VF). IMPELLA
group: Out of 12 patients, the device worked well in 5 patients,
but could not be positioned in the PA in 4 patients, also accompanied
by blood loss and VF. In 2 patients, full output of the pump could
not be achieved. In 1 patient, tilting of the heart was not possible
due to cardiomegaly despite of full pump output.
Conclusions: The use of a RVAD system during beating heart
surgery can maintain hemodynamic stability during beating heart
surgery, but can be a source of adverse events.
