Background: Cardiac neoplasms are classified in 2 groups: primary, which are reported with a worldwide incidence of 0.0017% to 0.23%, and secondary, which occur up to 40% more frequently. Myxomas are considered the most frequent primary cardiac neoplasms. They occur most frequently between the third and sixth decade of life. They are located mainly in the left atrium. The clinical manifestations of myxomas are constitutional symptoms and clinical signs of heart failure. Transthoracic echocardiography is the most widely used imaging study for diagnosis; surgical resection with the support of an extracorporeal circulation pump is the treatment of choice. Complications that can occur during surgery are embolisms, arrhythmias, and valve lesions. Clinical case: A clinical case of a 58-year-old female patient who underwent surgery for resection of left atrial myxoma is presented. Conclusions: Myxomas are pathologies that have a low incidence worldwide and nationally, for which a specific anesthetic and surgical management must be followed to avoid perioperative complications.

Primary cardiac tumors have a prevalence between 0.08 to 0.2%. being the benign tumors such as rhabdomyoma and myxoma the most common. However 10% of cardiac tumors can be malignant. Primary cardiac lymphoma occurs in 1.3% of all primary cardiac tumors and 0.5% of all non-Hodgkin's lymphomas. Patients present nonspecific symptoms, which causes difficulty in their early diagnosis. Diagnosis by imaging should be suspected when there is a right atrial mass that is enhanced with the contrast medium along with pericardial effusion. [ABSTRACT FROM AUTHOR]

The heart is very uncommonly affected by neoplasms, most of the times of metastatic nature; they are followed in order of frequency by the benign primary neoplasms and finally the malignant ones. Leiomyosarcomas are in the third place within the latter ones. Case Reports with this diagnosis are scarce, so it was decided to put at the scientific community disposal the case of a 79-year-old female patient, of urban origin, type II diabetic for more than 20 years and in addition, a previous history of heart failure about 25 years ago for which she was regularly treated. She was assisted at the Dr. Gustavo Aldereguía Lima General University Hospital in Cienfuegos, where she died. The work presents the case clinical and morphological characteristics and makes a brief allusion to the distinguishing characteristics of this neoplasm in general, in this unusual location.

Introduction: Cardiac tumors are rare; of them, the metastatic tumors are the most frequent. Of the primary tumors, only 25% are malignant, being the angiosarcoma the most common. It is a tumor of high malignancy, characterized by rapid growth, obstruction of cardiac valves and lung metastases. It is most common between 30 and 50 years, especially in men, with a ratio of 2:1. Its symptoms are nonspecific cardiovascular and its prognosis is poor, with a survival of nine to twelve months from diagnosis. Case report: A 50 years old woman with a history of hypertension and rheumatoid arthritis. She presented with dyspnea and impaired functional capacity. Transthoracic echocardiogram showed a mass of 6 cm in diameter, occupying the entire right atrium with tricuspid flow obstruction, associated with massive pericardial effusion with cardiac tamponade. Computed tomography (CT) of the brain, thorax, abdomen and pelvis discarded metastatic lesions. Surgical treatment was decided. The tumor and 70% of the free wall of the atrium were resected and biological prosthetic valve was installed, and the right atrium was reconstructed with autologous pericardium. She evolved favorably, without incident. Histopathological reports confirmed cardiac angiosarcoma. Discussion: Cardiac tumors are rare. They should be suspected in patients with cardiovascular symptoms, associated with intracavitary mass, pericardial effusion not explained by other causes, as well as the presence of thoracic metastases from an unknown primary tumor.
