This article focuses on a study related to cerebral injury following on pump and off pump cardiac surgery defined by functional MRI. Cognitive dysfunction affects up to half of all patients at discharge following cardiac surgery. Neuropsychological testing is the most commonly used method of assessment despite its limitations. Patients undergoing off pump surgery have significant preservation of cerebral activity with increasing memory load. The reduction in frontal activity in the on pump group maybe a manifestation of cerebral injury that occurs with cardiopulmonary bypass.
