Tissue Doppler imaging: clinical topics for the new millenium.
BACKGROUND
Tissue Doppler imaging is an echocardiographic technique that allows the selective visualization and quantification of myocardial signals. Its aim is to complement the conventional Doppler study, adding more and better information on specific topics of cardiovascular diseases. During the first seven years of the technique, much scientific work was produced and some clinical applications of the method have emerged.


METHODS
I--non ischemic heart disease: The technique has been widely used in diastology, in hypertrophic cardiomyopathy, in heart transplant patients and in arrhythmology. II--ischemic heart disease: The quantitative assessment of regional diastolic and systolic function makes the technique very promising during stress echocardiography and during percutaneous transluminal coronary angioplasty.


CONCLUSIONS
In 2000, tissue Doppler echocardiography is still a young, exciting and promising technique. Despite the fact that much has already been done, there is still a long way to go, implying a great amount of time and personal investment. How often do we feel that we are building a small part of the future?
