Fig. 1 Ultrasonic perturbations detected by a 5-MHz continuous-wave Doppler device are associated with both gaseous and particulate emboli. In this view, a 5-second monitoring period was captured immediately after cross-clamp release and an embolic shower was detected in the left carotid artery.

Fig. 2 The effect of increasing age on neuropsychologic outcome at 5 to 7 days and 1 month after coronary artery bypass grafting (CABG). Patients at age 50 years with deficits on two or more tests have a 67% chance of becoming normal at 1 month. By age 70 years that chance drops to less than 60%.

Fig. 3 Epiaortic and transesophageal echocardiographic scanning provides an additional level of protection to older patients who may face higher risks of brain injury owing to a greater likelihood of embolization secondary to aortic atheroma.
