摘　　要：目的探讨经食管超声心动图双平面法测量经导管主动脉瓣植入术(TAVI)患者主动脉瓣环径的可行性。方法对24例拟行TAVI的患者,术前分别采用经胸超声心动图(2D-TTE)、经食管超声心动图(2D-TEE)、三维经食管超声心动图(3D-TEE)及经食管超声心动图双平面法(Bip-TEE)测量主动脉瓣环径。比较4种方法测量的差异以及3DTEE测量值与另外3种方法测量值的相关性。结果 2D-TTE、2D-TEE、Bip-TEE与3D-TEE所测的主动脉瓣环径分别为(22.02±2.21)mm、(23.34±2.34)mm、(23.89±2.37)mm;(24.21±2.78)mm,4组测量值总体差异有统计学意义(F=3.88,P=0.01)。3D-TEE与2D-TEE、Bip-TEE所测量主动脉瓣环径差异无统计学意义(P均>0.05),2D-TEE与Bip-TEE测量值差异无统计学意义(P>0.05)。2D-TTE与3D-TEE、2D-TEE、Bip-TEE所测的主动脉瓣环径比较差异均有统计学意义(P均<0.05)。3D-TEE所测的主动脉瓣环径与2D-TTE、2D-TEE、Bip-TEE测值均呈正相关(r=0.79、0.88、0.94,P均<0.05)。结论经食管超声心动图双平面法可用于准确测量主动脉瓣环径,从而为TAVI提供可靠的瓣膜型号选择依据。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,2D-TEE,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 4groups was significant（F=3.88,P=0.01）.No statistically significant differences were found between Bip-TEE and 3D-TEE,2D-TEE and 3D-TEE,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.
