In a retrospective multicentre study, the diagnostic potential of transoesophageal 2D-echocardiography (TEE) as compared to precordial 2D-echocardiography (TTE) was determined in 154 patients with primary or secondary tumours of the heart. Additionally, the value of standard diagnostic parameters, such as symptoms, X-ray of the chest and electrocardiogram were evaluated. In 84 patients (24 male, 60 female; age 20-85, mean 56.6 years) intracardial tumours were present, and 70 patients (37 male, 33 female; age 18-79, mean 44.3 years) presented with peri- or paracardial tumours. The main symptoms of patients with intracardial tumours were dyspnoea (60.7%), vena cava syndrome (22.2%) and chest pain (20.2%). Embolization was found in 11.9%. Left or right atrial enlargement was observed on chest X-ray in 23 patients, and echocardiographic abnormalities in 17 cases. The patients with peri- or paracardial tumours presented with dyspnoea in 51.4% of cases, loss in body weight in 20.0% and with vena cava syndrome and chest pain in 17.1%. The chest X-ray was abnormal in 56 patients. Unspecific ST segment changes in the electrocardiogram were observed in five, and arrhythmias in seven cases. Diagnosis of atrial myxomas was achieved by TTE in 95.2%, by TEE in 100%, by angiography in 78.4%, by computed tomography (CT) or magnetic resonance tomography (NMR) in 70%. Identification of the attachment point was made by angiography in 8.1%, by TTE in 64.5% and by TEE in 95.2%. In 22 patients with intracardial tumours (myxomas excepted) diagnosis was achieved by TTE in 90.9%, by TEE in 100%, by CT or NMR in 88.9% and by angiography in 50%.(ABSTRACT TRUNCATED AT 250 WORDS)

The cause of acute and recurrent pericarditis is often a major concern for the clinicians in clinical practice. Several possible causes of pericarditis can be listed, as the pericardium may be involved in a large number of systemic disorders or may be diseased, as an isolated process. The reported diagnostic yield of extensive laboratory evaluation and pericardiocentesis is low in the absence of cardiac tamponade or suspected neoplastic, tuberculous, and purulent pericarditis. Patients with pericarditis can be safely managed on an outpatient basis without a thorough diagnostic evaluation unless a specific cause is suspected or the patient has high-risk features, or both. A targeted aetiological search should be directed to the most common cause on the basis of the clinical background, epidemiological issues or specific presentations. In developed countries the clinicians should rule out neoplastic, tuberculous, and purulent pericarditis, as well as pericarditis related to a systemic disease.

EMI is as frequent as rest ischemia during 5-FU infusion. Patients undergoing 5-FU continuous infusions should be adviced to avoid unusual efforts, to refer any cardiac symptom, and should be investigated for EMI.

Systemic CT plus pericardial window is a more effective treatment option compared with systemic CT alone and systemic CT plus drainage in patients with malignant effusions.

The prevalence of neoplastic pericardial diseases has changed over time and varies according to diagnostic methods. The diagnostic factor is usually the detection of neoplastic cells within the pericardial fluid or in specimens of pericardium, but the diagnosis may be difficult. Accurate sampling and cytopreparatory techniques, together with ancillary studies, including immunohistochemical tests and neoplastic marker dosage, are essential to obtain a reliable diagnosis. The goals of treatment may be simply to relieve symptoms (cardiac tamponade or dyspnea), to prevent recurrent effusion for a long-term symptomatic benefit, or to treat the local neoplastic disease with the aim of prolonging survival. Immediate relief of symptoms may be obtained with percutaneous drainage or with a surgical approach. For long term prevention of recurrences, various approaches have been proposed: extended drainage, pericardial window (surgical or percutaneous balloon pericardiostomy), sclerosing local therapy, local and/or systemic chemotherapy or radiation therapy (RT) (external or with intrapericardial radionuclides). The outcomes of various therapeutic approaches vary for different tumor types. Lymphoma and leukemias can be successfully treated with systemic chemotherapy; for solid tumors, percutaneous drainage and the use of systemic and/or local sclerosing and antineoplastic therapy seems to offer the best chance of success. The use of "pure" sclerosing agents has been replaced by agents with both sclerosing and antineoplastic activity (bleomycin or thiotepa), which seems to be quite effective in breast cancer, at least when associated with systemic chemotherapy. Local chemotherapy with platinum, mitoxantrone and other agents may lead to good local control of the disease, but the addition of systemic chemotherapy is probably relevant in order to prolong survival. The surgical approach (creation of a pericardial window, even with the mini-invasive method of balloon pericardiostomy) and RT may be useful in recurring effusions or in cases that are refractory to other therapeutic approaches.
