Cardiac surgery in Germany during 2005: a report on behalf of the German Society for Thoracic and Cardiovascular Surgery.

All cardiac surgical procedures performed in 79 German cardiac surgical units throughout the year 2005 are presented in this report, based on a voluntary registry, which is organized by the German Society for Thoracic and Cardiovascular Surgery. In 2005, a total of 98 860 cardiac surgical procedures (ICD and pacemaker procedures excluded) were collected in this registry. More than 8.4 % of the patients were older than 80 years, compared to 7.8 % in 2004. Hospital mortality in 54 126 isolated CABG procedures (9.7 % off-pump) was 2.9 %, while a mortality of 4.5 % was observed in 19 203 isolated valve procedures. This registry is an important tool of the German Society for Thoracic and Cardiovascular Surgery to ensure a continuous and voluntary quality assurance and illustrate the development of cardiac surgery in Germany.
