Blood pump is the core component of artificial ventricular assist device, and thrombosis is a severe complication of blood pump in clinical application. Methods of controlling and reducing thrombosis include materials surface modification, structure and parameters optimization of blood pump, and others. The typical symptoms of thrombosis and the hazard of various types of blood pump, the formation mechanism and primary factors for thrombosis, and the simulation prediction models for thrombosis were reviewed in this paper.
