[Transesophageal echocardiograph in the evaluation of proximal segments of coronary arteries].
The study was undertaken to assess the usefulness of TEE for evaluation of morphology and flow in coronary arteries. TEE (2D, spectral and color Doppler imaging) and coronary angiography were performed in 75 patients (pts)-41 with valvular heart disease and 34 with ischemic heart disease. Proximal coronary artery stenosis was detected by coronarography in 11 pts (9--left main coronary artery, 2--right coronary artery). TEE visualization of proximal coronary arteries was possible in all pts. Echocardiographic features of artery stenosis were: the narrowing of the vessel in 2D image (9 pts), high flow velocity spectral Doppler (4 pts, mean 135 cm/s vs 55 cm/s in normal arteries) and mosaic, turbulent flow in color Doppler (10 pts). Sensitivity and specificity of TEE for coronary artery stenosis detection was respectively 81%/98% for 2D imaging and 90%/100% for color Doppler. TEE is a new, noninvasive and safe method for the evaluation of proximal coronary arteries. Detection of LMCA stenosis prior to catheterization may enhance the safety of coronary angiography.
