title: [Transthoracic color Doppler echocardiography in the diagnosis of insufficiency of heart valve prostheses. A comparison with conventional Doppler sonography].
abstract: 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.
