[Clinical usefulness of intracoronary Doppler for prediction of coronary restenosis].
The Doppler guide wire is widely used in the diagnosis of heart diseases, and in particular including ischemic heart disease. It offers various advantages for application in tortuous and peripheral arteries, and in the detection of functional coronary stenosis that coronary angiography cannot detect. A number of multicenter trials have also shown that the Doppler guide wire is of value in predicting coronary restenosis after coronary intervention. On the other hand, the Doppler guide wire is influenced not only by the stenosis in the epicardial coronary artery, but also by stenosis in the vascular beds of coronary microcirculation. An appreciation of both the advantages and disadvantages of the Doppler guide wire and its usefulness is of considerable importance.
