Cardiac masses due to tumors (diagnosis, clinical manifestations and surgical treatment)

Abstract

Aim. To summarize the experience on the diagnosis and surgical treatment of primary benign and malignant cardiac tumors. Methods. The paper describes 37 clinical observations of endocavitary primary benign and malignant cardiac tumors: 26 (70.3%) cases of cardiac myxoma, 5 (13.5%) - rhabdomyosarcoma, 2 (5.4%) - angiosarcoma, 1 (2.7% ) - leiomyosarcoma, 1 (2.7%) - fibrosarcoma, 1 (2.7%) - liposarcoma. Patients were 15 (40.5%) males and 22 (59.5%) females aged 18 to 65 years. Endocavitary cardiac tumors were diagnosed by noninvasive tests: echocardiography, computed tomography, magnetic resonance imaging. Results. Patients with primary benign and malignant cardiac tumors had variable clinical manifestations. Symptoms of astenoneurotic syndrome, auscultatory and cardiophonographic signs simulating acquired or congenital valvular heart diseases, which often have a positional relationship; low-grade fever of unknown origin, weight loss were registered. Paraneoplastic syndrome was characterized by an increase in erythrocyte sedimentation rate, leukocytosis, monocytosis, dysproteinemia, polycythemia, hypochromic anemia, increased levels of C-reactive protein. Surgical excision of 25 cardiac myxomas and 8 malignant tumors of the heart was performed with cardiopulmonary bypass, pharmacological cardioplegia and general hypothermia. In 1 case the tumor resection was combined with coronary artery bypass grafting. In 3 patients suffering from malignant tumors, explorative thoracotomy was performed. Surgical revision, emergency and planned microscopic studies of removed cardiac tumors allowed to establish the final clinical diagnosis. Hospital mortality among patients operated for cardiac myxomas was 4.0%, for cardiac malignant tumors - 27.3%. Conclusion. Timely surgical treatment of patients with primary cardiac benign tumors (myxomas) leads to recovery and is accompanied by a relatively low mortality; better results of patients with cardiac endocavitary tumors treatment depend on the early detection and timely radical surgical excision.
