Primary and metastatic cardiac tumors: imaging characteristics, surgical treatment, and histopathological spectrum: a 10-year-experience at a German heart center.
BACKGROUND
Tumors of the heart are rare compared to other cardiac diseases. Their clinical symptoms vary from absent to nonspecific. This great variation and general paucity of symptoms related to cardiac tumors often result in delayed diagnosis and treatment.


METHODS
We retrospectively evaluated all patients who underwent cardiac surgery for a space-occupying lesion in the observation period between 2000 and 2010 at our hospital. Clinicopathological features, imaging characteristics, and disease outcomes were analyzed, and the results were compared with the available English literature.


RESULTS
During the last 10 years, 84 patients underwent resection of a cardiac mass at our center, i.e., 0.85% of the total number (n=9829) of all cardiac surgical operations performed in that period. The part of primary cardiac tumors was 73.8% (n=62; 59 benign and 3 malign tumors). In nine cases (10.7%), secondary cardiac tumors represented metastases of malignant tumors from different extracardiac locations. In 13 cases (15.5%), the mass represented cardiac thrombus. The majority of cardiac tumors were benign, and most of them were cardiac myxomas (n=48). Papillary fibroelastoma was the second most common primary tumor.


CONCLUSIONS
Our data in this study were comparable to the literature regarding the frequency and allocation of the different cardiac tumors. Our data are in line with previous reports that patients with benign cardiac tumors profit from surgical resection compared to those subjected to conservative treatment with the risk of central or peripheral embolisms. Concerning malignant primary cardiac tumors and cardiac metastases, surgery represents only a palliative strategy in most of the cases.
