Abstract:
Objective To explore the value of real-time three-dimensional echocardiography(RT-3DE)in patients with aortic valve plasty.Methods Eleven patients[6 male,5 female,mean age(26.27±8.19)years]with severe aortic regurgitation underwent echocardiographic examination using Philips Sonos 7500 and IE33 with a X4 probe.Results The diameters of aortic valvular annulus,aortic root,sinotubular j unction and ascending aortic were measured by RT-3DE and compared with those measured directly in operation,their correlation was r= 0.99,P＜0.05;r=0.98,P＜0.05;r=0.97,P＜0.05 and r=0.98,P＜0.05.RT-3DE and color RT-3DE could display aortic leaflet motion and the severity of aortic regurgitation clearly.They were also effective in analyse of the position,size and shape of a ventricular septal defect(VSD).Conclusions RT-3DE and color RT-3DE provides good insight into aortic valvular motion and the severity of aortic regurgitation,and allows to measure the diameter of aortic valvular annulus,aortic root,sinotubular junction and ascending aortic rapidly and accurately.
