Abstract:
Objective To study the the feasibility of real-time 3D transesophageal echocardiography (RT-3D TEE) in measuring the distance between the coronary artery ostia and the aortic annulus.Methods RT-3D TEE image of aortic root was collected intraoperatively in 18 cases who were refered to our center for transcatheter aortic valve implantation.The aortic annulus was reconstructed and the height of the annulus (H) was generated.Meanwhile RT-3D TEE and MDCT was used to determine the left coronary artery ostia-aortic annulus distance (E-LAA,C-LAA) and the right coronary artery ostia-aortic annulus distance (E-RAA,C-RAA).Results The display rate of right coronary artery was 94.4％ (17/18),with the left coronary artery 88.9％ (16/18) on the RT-3D TEE imaging.The height of the annulus(H) was lower than the distance between the coronary artery ostia and the aortic annulus(P ＜0.05).No statistically significant differences was found in the parameters of the distance between the coronary artery ostia and the aortic annulus between RT-3D TEE and MDCT (P ＞0.05).Conclusions RT-3D TEE imaging can display and measure the distance between the coronary artery ostia and the aortic annulus.
