[Primary right ventricular malignant fibrous histiocytoma; report of a case].

Primary malignant fibrous histiocytoma located in the right side of the heart is extremely rare. We reported a case with literal reviews. A 71-year-old woman was admitted of faintness due to hypotension and marked edema of her lower extremity. With no time she was deteriorated into cardiogenic shock. Echocardiography demonstrated a tumor like mass which occupied her whole right ventricular cavity. Emergency tumor resection was carried out because of her status. Histological and immunohistochemical studies revealed the tumor was malignant fibrous histiocytoma. She died of pulmonary failure on nineteenth day after surgery.

Cardiac metastatic liposarcoma.

Metastatic cardiac liposarcoma is extremely rare, with only 2 cases previously reported, to our knowledge; of those, only 5 involved surgical resection of right ventricular liposarcoma. The first such case in Japan involved a 61-year-old woman with metastatic liposarcoma of the right ventricle. Despite emergency resection, the patient died of severe congestive heart failure 6 days after operation. Her history included surgery for liposarcoma in the right knee 11 years previously, although it is very difficult to predict that metastasis would proceed thereafter to the cardiac cavity. This rare case suggests, however, that follow-up including examination for cardiac lesions is necessary long after resection of the primary lesion.

[Mitral valve replacement for three cases of hypertrophic obstructive cardiomyopathy--surgical treatment].

Three patients with obstructive cardiomyopathy underwent surgical treatment. Mitral valve replacement was performed in all three cases and myectomy of hypertrophic septal muscle was performed in one case. The pressure gradients between the left ventricle and the aorta was less than 10 mmHg in all cases after surgery, Clinical symptoms strikingly improved in three cases. An accurate surgical treatment could be achieved by choosing either myotomy-myectomy, mitral valve replacement or both in the setting of individual condition of each patients.

Piperidineacrylate derivatives as potential antiallergy agents.

A new series of piperidineacrylate derivatives was prepared and evaluated for antiallergic activity. Most of the compounds showed potent activities in the rat passive cutaneous anaphylaxis (PCA) assay. In particular, ethyl 1-[2-bis(4-fluorophenyl)methoxyethyl]-4-piperidineacrylate (1a) was more potent than oxatomide and terfenadine in this assay, and was selected for further study. Some pharmacological properties of 1a are presented.
