| 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3D-TEE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 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 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. |
