The study investigated echocardiographic findings after 1 month in 22 patients who received a CoreValve prostheses to treat aortic valve stenosis. Particular attention was paid to the evaluation of valvular leaks and the left ventricular wall thickness. Echocardiograms were obtained prior to implantation, at discharge and 1 month later. The patients鈥?mean age was 77 卤 4 years. At discharge, 16 patients (76%) had aortic regurgitation: 8 grade I and 8 grade II. At 1 month, only 13 (62%) presented with the condition: 10 grade I and 3 grade II, with 8 patients (38%) demonstrating a reduction of at least one grade (P < .005). The septal thickness decreased (from 14.2 卤 2聽mm at baseline to 11 卤 2.4聽mm at 1 month; P < .001), as did the posterior wall thickness (from 10.9 卤 2.4聽mm at baseline to 8.3 卤 1.2聽mm at 1 month; P < .001). In our patient series, the frequency and grade of residual aortic regurgitation after implantation of the CoreValve prosthesis decreased within 1 month, and favorable left ventricular remodeling was also observed.
