Abstract:
The Berlin Heart EXCOR is a pulsatile paracorporeal ventricular assist device (VAD) for neonates, infants, children and adults with congenital or acquired severe ventricular dysfunction. Berlin Heart EXCOR VADs are routinely used as either a bridge to a cardiac transplantation, or occasionally as a bridge to ventricular recovery. Our programmatic philosophy is to bridge neonates and infants with functionally univentricular ductal-dependent systemic circulation or functionally univentricular ductal-dependent pulmonary circulation who are at high risk for staged palliation because of important cardiac risk factors with a single-ventricle VAD (sVAD) as a bridge to a cardiac transplant. This video tutorial documents our approach to a patient who underwent ductal stenting and placement of internal flow restrictors at another institution and subsequently had an operation at the University of Florida that included placement of a Berlin Heart sVAD, removal of internal flow restrictors and placement of bilateral external pulmonary artery bands.
