Recently, a newly developed centrifugal pump, the Baylor‐Nikkiso pump, was approved for clinical use in the United States. This pump is the most compact centrifugal pump with a priming volume of only 25 ml. Although it is small, this pump can provide a flow of 4 L/min against a total pressure head of 300 mm Hg at 3,000 rpm. In vitro and in vivo validation of the Baylor‐Nikkiso pump has proved that this pump could effectively reduce blood trauma even under high total head pressure. In addition, 48‐h durability tests with biventricular bypass using calves verified the reliability of shaft sealing and anti‐thrombogenicity. Clinical trials of the Baylor‐Nikkiso pumps have been initiated in our department. This pump provides flows of 60–70 ml/kg/min with stable hemody‐namic conditions. No leakage or thrombus formation was observed. The results of the initial clinical experience of the Baylor‐Nikkiso pump suggest that it is suitable for cardiopulmonary bypass surgery.
