Background
The frequency of primary cardiac tumors is rare at about 0.3% by autopsy. Our objective was to investigate the characteristics and locations of cardiac tumors and to provide a prognostic analysis in our hospital.
Methods
We collected data on 95 patients with echocardiographic diagnosis or detection of cardiac tumors in a prospective analysis from 1999 to 2014. The median follow-up period was 43 months (0.5–183 months).
Results
The subjects included 56 men and 39 women with a mean age of 65 years. Clinical diagnosis revealed primary tumors in 61 patients (64%) and secondary metastatic tumors in 34 patients (36%). In the 61 patients, 41 patients (67%) underwent surgery and tissue samples were obtained. Of these 41 patients, benign tumors were found in 30 cases (73%). One patient (2%) was diagnosed with thrombus. Among the benign tumors, myxoma (67%) was the most common type followed by papillary fibroelastoma (23%). The most common site was the left atrium (35%) followed by the right atrium (25%). Primary malignant tumors were diagnosed in 10 cases (24%), including 6 angiosarcomas, 3 lymphomas, and 1 leiomyosarcoma. The diagnostic accuracy of echocardiography was 80%. The patients with benign tumors were all alive at the end of the follow-up period. In contrast, 7 patients with malignant tumors died (70%) (p < 0.0001).
Conclusions
Our data is in line with previous literature. Our study also suggests the necessity of extending our knowledge of the characteristics of cardiac tumors for diagnosis.
