TAVR with a self-expanding bioprosthesis was safe and effective in patients with symptomatic severe aortic stenosis at prohibitive risk for surgical valve replacement. (Safety and Efficacy Study of the Medtronic CoreValve System in the Treatment of Symptomatic Severe Aortic Stenosis in High Risk and Very High Risk Subjects Who Need Aortic Valve Replacement; NCT01240902).

clinicaltrials.gov Identifier: NCT00091637.

Event-related synchronization (ERS) after self-paced, voluntary brisk movement of the right and left thumb was studied in 17 patients with Parkinson's disease (PD) and 17 age-matched control subjects. All patients were receiving L-DOPA and/or DOPA-agonists. The movement-offset-triggered EEG data were analyzed in the 12- to 16-Hz, 16- to 20-Hz, and 20- to 24-Hz bands for eight time intervals after termination of movement. Significant differences in postmovement beta synchronization were observed in all three frequency bands. As compared with the control group, patients with PD showed a remarkably smaller beta ERS. This was the overall main effect for groups, as well as for interactions concerning side of movement and electrode positions. If beta ERS is a measure of recovery of the primary motor area after movement, our results indicate that this ability is impaired in PD patients.
