In 1981 Dr Jean Lintermans published, with Dr van Dorp, a superb vol ume, 'Differential Diagnosis in Pediatric Echocardiography'. It was 'state of the art' with a unique organization, starting with M-mode echocardiograph ic findings rather than the disease category, and included a segmental approach to diagnosis, and concluded with an invaluable section on normal echocardiographic values. This volume was a great help to many of us in pediatric cardiology who were discovering the great clinical value of the noninvasive approach to diagnosis. This gave us a 'running start' for our own entry into the field. At that time, the 2 D or sector echocardiogram was finding increasing usefulness and there were several illustrations of this tech nique, integrated into that volume. Since 1980, the field of 2 D echocardiography has grown enormously in its usefulness, to the point that it has reduced the need for invasive studies, and has enhanced the precision of invasive studies when required. It is now time for a systematic and thorough approach to this field, and I am delighted that Jean Lintermans has provided us with this book. The pictures are uniformly superb and are very well labelled. The organization is cen tered around diagnostic categories, but the same attention to detail is pre sent that made the first volume so useful. I particularly value the extensive documentation of diagnostic findings, with numerous literature citations."

Dr. Jean Lintermans came to Seattle in 1962 from his general pediatric residency at the University of Iowa. He worked with us in clinical pediatric cardiology and in our animal physiology laboratory for the next three years. He was the most productive individual in the history of our training program, publishing seven papers in those three years, four clinical papers and three involving pulsed ultrasonic flowmeters and implanted ultrasonic displacement devices in animals. The work, from laboratory to publication, was always done with the utmost attention to accuracy, and was well developed conceptually. Although English was not his native language, Jean's mastery of English was not only excellent, I felt that he actually communicated better than many of our native physicians. During the past year, I was delighted to learn that Jean was preparing a textbook on pediatric echocardiography with Dr. van Dorp, and was even more pleased to be asked to write a foreword .. However, the greatest pleasure came from actually reading this book, and finding that it does indeed have a unique approach, and with the additional genuine benefit to the reader of a thorough, consistent, segmental approach to the diagnosis of congenital heart disease.
