Real-time Doppler color flow mapping in stenotic valvular lesions
Two-dimensional real-time Doppler color flow mapping methods are early in their course of clinical use and further experience is obviously required to realize the full potential of this method for the evaluation of stenotic valvular lesions. Many new systems for Doppler color flow mapping are currently in development and promise to overcome some of the limitations induced by artifact, inadequate color renditions, and poor target acquisition. Newer systems are likely to follow the course of all ultrasound instrumentation and become smaller, more reliable, and less costly. This new technology provides a unique method for observing the spatial orientation of flow velocities in valvular stenosis and, thus, can be presently considered complementary to conventional imaging and Doppler methods for this purpose.
