Abstract
Cardiac tumors can imitate the symptoms of several cardiac diseases as e.g. valve diseases, endocarditis or even myocardial infarction. Not infrequently they are found by chance and at any rate rarely in the daily work of a cardiac surgeon. This is why there are only few and varying data about the frequency and the distribution of types of tumors as well as the operation techniques and the outcome. Nevertheless there is accordance that the majority of cardiac tumors are fortunately benign and patients can be completely cured by undergoing an operation.We want to give an overview about the actual knowledge concerning cardiac tumors and operation techniques.
