Abstract:
Objective To explore the feasibility of biplane-transesophageal echocardiography (Bip-TEE) in measuring the aortic annulus dimension (AAD).Methods Totally 24 patients underwent transcatheter aortic valve implantation (TAVI) were collected,and their AAD was measured by two-dimensional transthoracic echocardiography (2D-TTE),two-dimensional transesophageal echocardiography (2D-TEE),Bip-TEE and three-dimensional transesophageal echocardiography (3D-TEE) respectively.These four methods were compared with each other.The correlation between 3D-TEE measures and other three methods were analyzed.Results The AAD measured by 2D-TTE,2DTEE,Bip-TEE and 3D-TEE were (22.02±2.21)mm,(23.34±2.34)mm,(23.89±2.37)mm,(24.21±2.78)mm,respectively.The differences among 4 groups was significant (F=3.88,P=0.01).No statistically significant differences were found between Bip-TEE and 3D-TEE,2D-TEE and 3DTEE,Bip TEE and 2D-TEE (all P＞0.05).There were significant differences between 2D-TTE and 2D-TEE,2D-TTE and Bip-TEE,2D-TTE and 3D-TEE (all P＜0.05).The AAD measured by 3D-TEE were positively correlated with that of 2D-TTE,2D-TEE,Bip-TE (r=0.79,0.88,0.94,all P＜0.05).Conclusion Bip-TEE is a feasible method to measure the AAD rapidly and can provide reliable measurements for the prosthetic valve size in TAVI.
