Color-coded and conventional pulsed wave/continuous wave Doppler detection of valvular or paravalvular regurgitation in 59 patients with 67 cardiac valve prostheses were compared; 21 patients had known regurgitation determined by auscultation. Analysis of the color-coded Doppler findings was made from videotape and blinded as to patient identity and clinical findings. Conventional Doppler Sonography detected 36 instances of aortic and 3 of mitral prosthetic regurgitation. Color-coded Doppler investigation detected 27 instances of aortic and 1 of mitral prosthetic regurgitation resulting in a sensitivity of 72% and specificity of 100% as compared to conventional Doppler sonography. All 21 patients with a regurgitant murmur had pathological conventional Doppler findings, but 3 of them did not show regurgitant flow in the color-coded Doppler examination. The apical four chamber view contributed most to the colour-coded Doppler detection of regurgitant flow, followed by the parasternal long axis view.
对59例植入67个心脏瓣膜假体的患者进行了彩色编码和传统脉冲波/连续波多普勒检测瓣膜或瓣周反流的比较；21例患者经听诊确定存在已知反流。对彩色编码多普勒检查结果的分析是通过录像带进行的，且对患者身份和临床检查结果不知情。传统多普勒超声检测到36例主动脉瓣人工瓣膜反流和3例二尖瓣人工瓣膜反流。彩色编码多普勒检查检测到27例主动脉瓣人工瓣膜反流和1例二尖瓣人工瓣膜反流，与传统多普勒超声相比，敏感性为72%，特异性为100%。所有21例有反流性杂音的患者传统多普勒检查结果均异常，但其中3例在彩色编码多普勒检查中未显示反流信号。心尖四腔心切面在彩色编码多普勒检测反流信号中贡献最大，其次是胸骨旁长轴切面。
