Due to the isolation of German medicine in World War II accompanied by the destruction of many hospitals, German pediatricians did not show any serious interest in the treatment of children with congenital heart diseases, nor did they take notice of the progress achieved by Helen Taussig, Alfred Blalock and other cardiologists and surgeons in the western world. This problem was even worse in East Germany. Only a few German internists and forward-looking surgeons were able and ready to take care of this group of principally operable children in places like Bonn/Düsseldorf, Marburg/Munich, Berlin, and Hamburg. However, in the early 1950s some directors of pediatrics at university hospitals--largely motivated by the cardiac surgeons--allowed or even encouraged younger colleagues to concentrate on pediatric cardiology and to begin application of heart catheterization and angiocardiography. In 1960 a group of colleagues interested in pediatric cardiology met for the first time in Frankfurt and became the nucleus of the future "working group" (1969) and finally the "German Society of Pediatric Cardiology" (1974). By 1972 pediatric cardiology had been approved as an independent (sub)specialty. Colleagues and friends from surrounding countries (Austria, Great Britain, Sweden, Switzerland, and the Netherlands) and also from the US and some eastern countries were either members or regular guests during or between the meetings. Pediatric cardiology is now represented in Germany by specialized practitioners, trainees and assistants who work in both community and university hospitals, and in specialized departments. Due to the foresightedness of the Chief of Pediatrics, Prof. G. Joppich, the first Chair of Pediatric Cardiology was founded in Göttingen in 1960 under the direction of A. Beuren. Another model of interdisciplinary cooperation between pediatric cardiologists, bioengineers, mathematicians and computer scientists was established in Kiel in 1966. In other places pediatric and adult cardiologists were brought together in "Heart Centers" with cardiovascular surgeons. The first of these Heart Centers was founded in 1974 in Munich under the directorship of K. Bühlmeyer and comparable centers were later established in Bad Oeynhausen (1985) and Berlin (1986). Following reunification in 1990, pediatric cardiologists from the east and west came together. Thus, within the last three to four decades German pediatric cardiology gradually caught up with international standards and in some fields of cardiovascular research even assumed a leading role. The care of the growing numbers of surviving patients with congenital heart disease has become a new challenge that has to be met by experienced cardiologists. To maintain the level of competence, future activities should however, not only concentrate on the optimal care of patients with congenital heart disease but also be responsible for cardiovascular research.
