Central nervous system metastases as the presentation of primary cardiac sarcoma are a very rare entity, with only a few previously reported cases. Sarcomas specifically make up 10 to 20% of all primary cardiac tumors. Patients with primary cardiac tumors typically present with cardiac symptomatology that may include arrhythmias, obstruction to blood flow and valve function, or symptoms of hear...
Primary malignant tumors of the heart, specifically cardiac sarcomas, are rare and mainly diagnosed at autopsy. Acute Budd-Chiari syndrome is a recognized cause of acute liver failure and has been associated with several rare cardiac tumors: atrial myxoma, caval rhabdomyosarcoma, and primary cardiac adenocarcinoma. We present the first case of a fatal, highly differentiated cardiac synovial sar...
Cardiac masses represent a diagnostic challenge because decisions about treatment are based on imaging techniques. Echocardiography, magnetic resonance (MR) and computed tomography (CT) are fundamental for the detection, characterization, and staging of cardiac masses as well as for planning their treatment. Most primary cardiac tumors are benign; myxomas, papillary fibroelastomas, and lipomas ...
Endoscopic techniques have expanded in recent years and now have the potential to be useful not only in digestive diseases but also in diseases usually seen by other departments. Cardiac tumors require surgical resection to prevent tumormediated embolism [1]; however, a left ventriculotomy significantly decreases the ejection fraction [2]. We previously reported two cases of cardiac surgery usi...
Primary cardiac sarcomas are rare and histologically diverse, with single tumors able to demonstrate histological heterogeneity. Consequently, they often misdiagnosed as other common tumors, such myxoma or metastatic malignancies. Incorrect diagnoses can result in incomplete surgeries, inadequate treatment regimens, early recurrence. In our experience, based on the diverse cytological character...
269 THE AMERICAN JOURNAL OF GERIATRIC CARDIOLOGY 2005 VOL. 14 NO. 5 S is the leading cause of morbidity in the elderly and the third leading cause of mortality in the United States. Cardioembolic causes may account for approximately 15%–20% of all strokes.1 The potential sources of cardiogenic embolism include atrial fibrillation, left ventricular dysfunction, rheumatic heart disease, prostheti...
BACKGROUND Cardiac tumors in children are rare. Of the cases reported in the literature, nearly all are benign and managed conservatively. METHODS This is a retrospective, observational study of pediatric patients <18 years who presented for surgical evaluation of a cardiac tumor, between 1969 and 2014 at a tertiary care children's hospital. Presentation, pathology, management, and outcomes w...
BACKGROUND To evaluate indications and results of surgery for primary cardiac tumors in children. METHODS AND RESULTS Eighty-nine patients aged ≤18 years undergoing surgery for cardiac tumor between 1990 and 2005 from 16 centers were included retrospectively (M/F=41/48; median age 4.3 months, range 1 day to 18 years). Sixty-three patients (68.5%) presented with symptoms. Surgery consisted of ...
This chapter will cover basic cardiac anatomy and tumors that are commonly found in the heart. The heart is divided into four chambers: left atrium, right atrium, left ventricle, and right ventricle. Different cardiac chambers have a propensity to have different cardiac masses or tumors. Cardiac tumors are rare entities: metastasis to the heart from another primary cancer is 30 times more likel...
Overall, the prevalence of primary cardiac neoplasms is approximately 0.3% and these masses should be distinguished from the myriad of other primary and secondary processes that can occur in the heart. Tumors within, attached to, or near the heart can cause direct cardiac damage, can result in thrombus formation, can compromise blood flow and can embolize distally. Hence, proper diagnosis is cl...
