This imaging case report demonstrates abnormal right ventricular masses of primarily unknown origin. The woman was admitted because of right heart failure symptoms. Echocardiography showed the masses exclusively related to the right ventricular endomyocardium and extending through the entire length and breadth of the ventricle. Systolic function was normal without evidence of outflow tract obstruction. The patient died in 3 days because of multisystem failure. Autopsy findings confirmed metastasis on the right ventricle and histopathology demonstrated the infrequent finding of metastasis from uterine squamous cell carcinoma, which had been operated on 5 years before.
Familial cardiac myxoma is a rare syndrome which constitutes approximately 10% or less of all myxomas. We describe a rare case of LA and LV mass simultaneously in a 35-year-old female presenting to our hospital for evaluation of recurrent cardiac myxoma. Echocardiography revealed both LA and LV mass. Surgery was done and histological findings confirmed the diagnosis of myxoma.
Two cardiac myxomas, one in the right ventricle and another one in the right atrium causing pulmonary embolism, was removed in a 21-year-old male. In this patient, we visualized two more recurrences 6 and 11 years later one in the left atrium and the other in the left and right atrium.

A cardiac leimyosarcoma is an extremely rare tumor. We report a case of complete resection of a cardiac leiomyosarcoma extending into the pulmonary trunk and the right pulmonary artery using the Freestyle bioprosthesis (Medtronic, Inc, Minneapolis, MN) and Xenomedica graft (Baxter Healthcare Corp, Horw, Switzerland). Extensive resection and reconstructive surgery with the addition of radiotherapy prolonged the patient's life.
Nineteen recurrences of a left atrial myxoma have been reported in 16 patients. This paper deals with the removal of a right ventricular myxoma three and one-half years following excision of a left atrial tumor. Because of the possibility of recurrence, postoperative follow-up of all patients with intracardiac myxomas is mandatory.

A rare case of neoplastic thrombotic endocarditis of the tricuspid valve in a patient with poorly differentiated follicular carcinoma of the thyroid is described. Although some previous reports documented extension of the follicular thyroid carcinoma into the great veins of the neck to the right cardiac chambers, this seems to be the first report of a neoplastic thrombotic lesion of the tricuspid valve in a patient with thyroid carcinoma. In our institute, where about 2,500 autopsies are performed yearly, and about 600 valvular lesions are discovered, such a lesion was never detected. In patients with carcinoma, a neoplastic thrombotic endocarditis may be a source of microembolic neoplastic spread leading to a possible pulmonary colonisation.
Left ventricular myxoma is a rare benign cardiac tumor. Surgical excision is the treatment of choice and completeness of removal is mandatory to avoid late recurrence. A case is presented in which aortic transvalvular video-assisted cardioscopy was used to facilitate removal.
Cardiac leiomyosarcoma is a very rare entity that is found in less than 0.2 % of all cardiac tumors. At the time of primary diagnosis, it often shows advanced local invasion or may even be metastasized. Thus, complete resection can not easily be achieved. Cardiac transplantation has been reported as a therapeutic option. Here, we report on a case of a leiomyosarcoma reoccurrence arising 2 years after initial surgery. We performed a radical redo-extirpation without the necessity of transplantation.
During a routine prenatal ultrasound a huge tumor was diagnosed located in the left ventricle and left atrium with complete obstruction of the left ventricular inflow tract. On the first day of life, urgent surgical intervention was necessary because of progressive heart failure with univentricular physiology. Intraoperatively, the tumor mass was found to originate from the left ventricular wall, reaching into the left atrium. Histological examination revealed a rhabdomyoma.
