Key result
Bio-Medicus centrifugal pump support achieves ~60% device weaning in refractory postcardiotomy heart failure.
Why the study?
Assisted circulation is used for postcardiotomy heart failure unresponsive to inotropic drugs and aortic counterpulsation, but experience with the Bio-Medicus centrifugal pump is limited.
Does the Bio-Medicus centrifugal pump provide effective circulatory support and improve survival in patients with refractory postcardiotomy heart failure?

Does the Bio-Medicus centrifugal pump provide effective circulatory support and improve survival in patients with refractory postcardiotomy heart failure?
The Bio-Medicus centrifugal pump can successfully support and salvage a subset of patients with refractory postcardiotomy heart failure, though bleeding and renal failure remain major fatal complications.
Paolini et al. (1994) conducted an observational in postcardiotomy heart failure (n=10). Bio-Medicus centrifugal pump was evaluated on Weaned from the device. Support with the Bio-Medicus centrifugal pump in 10 patients with refractory postcardiotomy heart failure resulted in 60% being weaned from the device and 40% surviving to discharge.
