The transpulmonary contrast-enhanced Doppler technique using sonicated albumin is useful for assessing the severity of aortic stenosis even in patients with poor Doppler recordings, although the duration of signal enhancement might be affected by left ventricular systolic pressure.

Early diagnosis and β-blocker therapy for high-risk patients with LQTS are important for prevention of cardiac events during pregnancy and the postpartum period, and β-blocker therapy may be tolerated for babies in LQT-P cases.

Intravenous injection of sonicated albumin can enhance the Doppler flow signals in the left heart chambers. This effect may be useful to improve the sensitivity of the Doppler system for detecting abnormalities of left heart blood flow such as mitral regurgitation.

SUMMARYWe report a case of malignant lymphoma whose initial symptoms were heart failure. An echocardiogram showed a large tumor in the right ventricle, and a definitive diagnosis was obtained at autopsy. Of particular interest in our case, the lymphoma was confined to the heart and a mediastinal lymph node, with its greatest bulk being intracardiac. This case is a rare manifestation of malignant lymphoma. (Jpn Heart J 35: 111-115, 1994) Key words:Cardiac tumor Malignant lymphoma Ga scintigraphy ARDIAC involvement of malignant lymphoma is not rare, accounting for approximately 20 per cent of all patients autopsied with this type of neoplasm.1) However, the vast majority of these patients also have widespread extracardiac lesions and do not have symptoms referable to cardiac involvement.2) Lymphomas initially presenting with cardiac symptoms and as a cardiac tumor are, in contrast, extremely rare. We describe one such case here. CASE REPORTA 64-year-old man was admitted because of a right ventricular mass and pericardial effusion. Five weeks before admission he began to experience dyspnea on exertion caused by climbing one flight of stairs, and pretibial edema. Three weeks before entry he was admitted to another hospital, where two-dimensional echocardiography demonstrated a right ventricular mass and massive pericardial effusion. Two weeks later systemic arterial pressure fell and pericardial drainage by pericardiotomy was performed. Cytological examination of the fluid and biopsy of the pericardium at this time did not reveal any specific pathological findings. He was referred to our hospital.On physical examination, the patient appeared moderately ill. The blood pressure was 130/86mmHg, the pulse was 110/min and regular. No lymphadenopathy or rash was found. The jugular venous pressure was moderFrom the
