This study evaluated the first clinical application of a new, totally bearingless centrifugal blood pump (CentriMag). Material and methods: A centrifugal pump consisting of an electromagnetic suspended impeller was used as a blood pump during beating-heart coronary artery bypass grafting in 11 patients (mean weight, 77.4 kg). Heparin in a bolus ...

Contemporary ventricular assist device therapy results in a high rate of successful heart transplantation but is associated with bleeding, infections, and other complications. Further reductions in pump size, centrifugal design, and intrapericardial positioning may reduce complications and improve outcomes.

Abstract: The use of cardiopulmonary bypass (CPB) in cardiac surgery has often been associated with postoperative organ dys-function. Roller and centrifugal pumps produce non-pulsatile flow (NPF) by default, and this still is the most widely used mode of perfusion. The development of pulsatile pumps has allowed comparisons to be made with NPF.

The roller pump with the standard occlusion setting (just non-occlusive) caused hemolysis that was the same or higher than that of the centrifugal pump . Blood damage in centrifugal pumps is primarily caused by shear stress, time, negative pressure, and turbulent flow and can differ according to different designs.

Based on the positive effects and improved perioperative outcomes of MiECC in adult cardiac surgery, this perfusion concept appears particularly attractive to pediatric cardiac surgery. So far, there are no reports on the clinical application of a MiECC system for corrective surgery in neonates and children.
