Catheter-delivered therapeutic ultrasound angioplasty is a new technique for use in the treatment of obstructive vascular disease. The treatment differs from balloon angioplasty in that it has been shown experimentally to cause disintegration of calcific and fibrotic atherosclerotic plaques, thrombus dissolution and arterial vasodilation. In contrast to laser technology, ultrasound systems are relatively inexpensive and simple to use and maintain. In the clinical trials detailed in this text, ultrasound angioplasty has been shown to be feasible and safe. Ultrasound Angioplasty is a comprehensive text, addressing the theoretical, experimental and clinical issues. The international contributions reflect the excitement, interest, spirit and cooperation in the research and development of therapeutic ultrasound.

An international meeting of experts on Cardiovascular Imaging by Ultrasound was held in Aachen from 26-27 April, 1991. It provided new and interesting insights into what has already been achieved in ultrasound-based cardiovascular diagnosis and therapy and what will be introduced in clinical practice in the near future. Since the introduction of ultrasound in clinical practice in 1984 there has been no other physical principle that has added and will continue to add so much to clinical diagnosis and therapy. Echocardiography, once established as a non-invasive diagnostic tool, is increasingly becoming an invasive technique for cardiovascular imaging. This book contains the edited contributions from 38 scientists and engineers from all over the world who presented the most up-to-date findings on 2-dimensional echocardiography, different Doppler modalities, contrast and stress echocardiography and the different modalities of transesophageal echocardiography, including mono-, bi- and multiplane TEE, as well as pulsed and CW-Doppler application via TEE. Exciting and promising developments are discussed in the field of intravascular ultrasound, tissue characterization, ultrasound ablation, ultrasound-based 3-dimensional reconstruction of the heart, and high frequency Doppler analysis.

In the past, coronary arteriography was the only modality available to provide high quality images of the coronary anatomy. Quantitative coronary arteriography (QCA) was developed, implemented, validated and extensively applied to obtain accurate and reproducible data about coronary morphology and the functional significance of coronary obstructions. Over the last few years extensive basic technological research supported by clinical investigations has created competing modalities to visualize coronary morphology and the associated perfusion of the myocardial muscle. Currently, the following modalities are available: X-ray coronary arteriography, intracoronary ultrasound, contrast- and stress-echocardiography, angioscopy, nuclear cardiology, magnetic resonance imaging, and cine and spiral CT imaging. For all these imaging modalities, the application of dedicated quantitative analytical software packages enables the evaluation of the imaging studies in a more accurate, reliable, and reproducible manner. These extensions and achievements have resulted in improved diagnostics and subsequently in improved patient care. Particularly in patients with ischaemic heart disease, major progress has been made to detect coronary artery disease in an early phase of the disease process, to follow the atherosclerotic changes in the coronary arteries, to establish the functional and metabolic consequences of the luminal obstructions, and accurately to assess the results of interventional therapy. Aside from all these high-tech developments in cardiac imaging techniques, the transition from the analogue to the digital world has been going on for some time now. For the future, it has been predicted that the CD-R will be the exchange medium for cardiac images and DICOM-3 the standard file format. This has been a major achievement in the field of standardization activities. Since these developments will have a major impact on the way images will be stored, reviewed and exchanged in the near future, an important part of this book has been dedicated to DICOM and the filmless catheterization laboratory. Cardiovascular Imaging will assist cardiologists, radiologists, nuclear medicine physicians, image processing specialists, physicists, basic scientists, and fellows in training for these specialties to understand the most recent achievements in cardiac imaging techniques and their impact on cardiovascular medicine.

Today, coronary artery disease is one of the major causes of mortality and morbidity in the Western World. In the last decade many major diagnostic and therapeutic advances have been made, considerably furthering our potential in the management of coronary artery disease. At the same time, a new generation of cardiac tools has appeared. The field which has, perhaps, undergone the most important technological innovations is echocardiography. Nowadays, in fact, the world of ultrasounds ofters the cardiologist a wide range of technical applicatons: two-dimensional real-time imaging, intra-and extra-cardiac Doppler flow measurements, real-time imaging of cardiac struc ture and flow by 2D color Doppler, high resolution cardiac imaging by transesophageal echocardiography, tissue characterization by analysis of ultrasound wave characteristics, information on myocardial perfusion by con trast echocardiography, etc. Thanks to these technical improvements and to its consequent increased potentiality, echocardiography now plays an impor tant and irreplaceable role in the management of all cardiac diseases. In the field of coronary artery disease, echocardiography can reliably be used not only in the acute phases of the disease to derive useful functional and prog nostic information but also as a stress diagnostic procedure (thanks to new stress modalities and the continuing improvement of reviewing digital sys tems) for the diagnosis of coronary artery disease and for the evaluation of various therapeutic interventions. Furthermore, other promising applications of ultrasounds in this disease are currently being investigated: tissue charac coronary artery anatomy terization, myocardial contrast echocardiography, and flow evaluation by specially-designed ultrasound catheters.

Coronary Pressure

Cardiologists must answer three important questions when evaluating and treating patients with a coronary artery stenosis. As a physiologist: "What is the effect of this stenosis on coronary blood flow and myocardial function?"; as a clinician: " Is this lesion responsible for the patient's symptoms?"; and finally as an interventionalist: "Will revascularization of this artery improve the patient?" Fundamentally, the answer to these questions can be given to a large extent by measuring coronary pressure. That is the rationale of writing this book. 1. 1 Historical overview. Andreas Gruentzig and most interventional cardiologists in the early days of PTCA, had the intuitive feeling that pressure measurements could help to establish the severity of a coronary stenosis and to monitor the progress and result of a coronary intervention. At that time, measuring coronary pressure by the balloon catheter was part of a standard procedure. A residual transstenotic gradient of less than 15 mmHg was generally considered as a good result. Later, however, it turned out that measuring these (resting) gradients with balloon catheters was inaccurate an only had a limited prognostic value. Moreover, because there was no consistent theory to correlate pressure measurements to blood flow, the interest in measuring coronary pressures faded and disappeared almost completely with the introduction of new balloon catheters not intended for pressure measurement.
