Intracoronary ultrasound is a rapidly evolving imaging modality and the increasing number of published studies indicates that the technique is safe and provides incremental and more detailed diagnostic information than coronary angiography.
The technique has the potential to study the pathobiology of atherosclerosis, to clarify the significance of angiographically equivocal lesions and has helped us to understand the mechanisms, effects and complications of catheter-based revascularization procedures. Combinations of imaging and therapeutic devices are being developed for both guidance...

Present day cardiology is in great need of non invasive, non toxic, and inexpensive devices which permit the delineation and visualization of normal and abnormal intracardiac structures, the calculation of intra- cardiac volumes and study of contractility of the cardiac muscle. All of these may become within our reach if the principles outlined in this book and the preliminary clinical experience can be validated in general cardiac practise. The gist of one of the devices (visualization of the in vivo moving heart recorded on a short motion picture) is available to the interested reader on a...
