Haemodynamic assessment was done by colour flow mapping and Doppler interrogation by both Transthoracic (TTE) and Transesophageal echocardiography (TEE) in 40 consecutive patients (mean age 36.6 +/- 12.35 years) with prosthetic valves. There were 30 cases of mitral (MVR) and 12 aortic (AVR) valve replacement. Major purpose of the study was to detect the sensitivity of TEE in detecting prosthetic valve malfunction particularly in comparison to TTE. Pannus was detected in 3 and 8 cases of MVR (p < 0.01) by TTE and TEE respectively; however, TEE was found to be of equal status in detecting pannus over AV (2 cases). Physiological regurgitation in MVR and AVR was detected in 13% and 25% by TTE and 20% and 33% by TEE respectively. Paravalvular leak was detected in 3 cases of MVR by TEE compared to only case by TTE. Though it is difficult to deduce any specific conclusion from this small number of patients, there is definite trend to higher sensitivity in detecting disorders with TEE specially for mitral prostheses.
对40例（平均年龄36.6±12.35岁）人工瓣膜置换患者进行经胸（TTE）和经食管超声心动图（TEE）检查，通过彩色血流图和多普勒询问进行血流动力学评估。其中二尖瓣置换（MVR）30例，主动脉瓣置换（AVR）12例。本研究的主要目的是检测TEE在检测人工瓣膜功能障碍方面的敏感性，特别是与TTE相比。TTE和TEE分别在3例和8例MVR中检测到瓣周漏（p<0.01）；然而，发现TEE在检测主动脉瓣瓣周漏方面（2例）与TTE地位相当。TTE分别在13%和25%的MVR和AVR中检测到生理性反流，TEE分别在20%和33%中检测到。TEE在3例MVR中检测到瓣周漏，而TTE仅检测到1例。尽管从这少量患者中难以得出任何具体结论，但TEE在检测疾病方面具有更高敏感性的明确趋势，特别是对于二尖瓣人工瓣膜。
