From 1973 through 1987, 155 radioisotope-powered "nuclear" pacemakers were implanted in 132 patients at the Newark Beth Israel Medical Center. The longevity of the first 15 devices, all of which were fixed-rate (VOO) pacemakers, was significantly better than that of 15 lithium-chemistry demand (VVI) pacemakers used as control devices (p = 0.0002). Of the entire cohort of 155 nuclear pacemakers, 136 were VVI devices and 19 were VOO units. The patients with VOO pacemakers needed reoperations more often than did those with VVI pacemakers, chiefly for mode change (p less than 0.001). Power-source failure was observed in only 1 case, but 47 nuclear pacemakers were removed for other reasons, including component malfunction (15 units), mode change (12 units), high pacing thresholds (8 units) and lead or connector problems (5 units). The actuarial survival at 15 years was 99% for power sources and 82% for the entire pacing systems (pulse generators plus leads). The frequency of malignancy was similar to that of the population at large and primary tumor sites were randomly distributed. Deaths most commonly were due to cardiac causes (68%). Thus, nuclear pacemakers are safe and reliable and their greater initial cost appears to be offset by their longevity and the resulting decrease in the frequency of reoperations. It is reasonable to suggest that further use be made of long-lasting nuclear power sources for modern pacemakers and other implantable rhythm-management devices.

The authors report 12 cases of metastatic pericardial effusions with clinical manifestations. Primary bronchial cancer is the most frequent with 7 cases; in 3 of these patients, the original manifestation is a tamponade. The contributions of sonocardiography to the diagnosis are analyzed: evaluation of hemodynamic tolerance and visualization within the effusion, in 4 out of 7 patients undergoing bidimensional sonocardiography, of dense masses, implanted on the visceral layer of the pericardium; the frequent epicardic location of these metastases may be explained by preferential invasion of the visceral layer by retrograde lymphatic route. The advantage of pericardial cytology is discussed. From the therapeutic standpoint, a pleuro-pericardial window or tetracycline instillation tend to prevent a recurrence of the effusion and the risk of tamponade; the neoplastic process is controlled with local and/or general chemotherapy and radiotherapy; therapeutic strategy depends on the sensitivity of the primary tumor. The prognosis remains very dim with a mean survival of 3.7 months in our series.

Pheochromocytoma was diagnosed in a male of 38 on the basis of severe and progressive hypertension associated with marked increases in urinary catecholamines and vanilmandelic acid. Left extra-adrenal topography was examined by tomography and confirmed by surgical treatment involving exeresis of the primary tumor and the metastatic latero-aortic lymph nodes, thus corroborating the diagnosis of malignancy. Complementary post-operative radiotherapy was performed on the abdomen. Eighty months later the patient is making good progress.

Among the patients who were examined with bone scintigraphy between April 1985 and March 1991, there were 27 patients whose initial clinical manifestation was bone metastasis and who were surveyed for the primary tumor site. The primary tumor site could be identified in 20 patients (74%), consisting of 9 patients with lung cancer, 3 with prostate cancer, 3 with hepatoma, 2 with renal cancer, and one each with thyroid cancer, adrenal cancer, and pleural malignant mesothelioma. In 17 of the 20 patients, the primary site had been detected within two months after presentation. Examinations which were helpful in identifying the primary site included chest radiography, sputum cytology, abdominal sonography, serum prostatic acid phosphatase level and pathologic examination of biopsy specimens. 99mTc-PMT scintigraphy was useful in the diagnosis of the hepatoma when accumulation was observed at the metastatic sites. In 2 patients, lung cancer had been recognized using follow-up chest radiography 3 and 6 months after presentation, respectively. One patient was diagnosed at autopsy as having adrenal cancer. In 7 patients the primary site remains unknown. Histology examination of the biopsy specimen performed in 6 of these patients revealed 4 to be adenocarcinoma and 2 undifferentiated carcinoma. The average survival period of the 17 patients who died was 9.5 months. Four patients are alive, and the outcome in the remaining 6 could not be determined.

Antemortem diagnosis of inferior vena cava (IVC) and cardiac metastasis of hepatocellular carcinoma (HCC) is difficult but important before consideration of curative resection. There are only a few cases of cardiac metastasis of HCC which have been diagnosed antemortem by echocardiography. Accordingly, 18 consecutive patients with HCC who were potential candidates for curative resection were studied by transthoracic (TTE) and transesophageal echocardiography (TEE). One (6%) and two (11%) patients had cardiac and IVC metastasis of HCC, respectively, which was detected by two-dimensional TTE. In contrast, by using TEE, four patients (22%) showed tumor invasion of the IVC, of whom two (11%) had tumor mass extending into the right atrium (RA). There was no significant difference in age, serum level of alpha-fetoprotein, and percentage of right liver lobar involvement between those with and without cardiac metastasis. Patients without cardiac metastasis detected on TTE or TEE had significantly longer mean duration of survival (5.0 +/- 2.1 vs. 2.1 +/- 1.0 months; p < 0.05). In summary, TEE may be more useful than TTE in the detection of cardiac metastasis of HCC, which occurred in 22% of patients whose primary tumor was considered to be surgically resectable in our series. This can be safely performed in patients with HCC and can provide optimal visualization of the IVC and RA. The high prevalence of subclinical cardiac metastasis in HCC mandates the use of TEE in all patients with HCC prior to surgical intervention.

A 57 years old man was operated for aortic valve replacement. During the operation a mediastinal lymph node was biopsed with the result of undifferenciated large cell carcinoma with neuroendocrine features. Three months after surgery the patient died of non-cardiac related reasons, postmorten examination was not performed. Although the primary tumor could not be assessed, probably the lung was the original location. The histological classification of lung cancer is exposed, with special reference in the undifferenciated large cell type with neuroendocrine features.

The choice therapy of malignant pericardial effusion is controversial. Pericardiocentesis is usually successful in alleviating tamponade, but unfortunately, that tamponade recurs frequently and patients are then again exposed to a critical situation and need hospitalization. Several different approaches have been advocated in order to prevent reaccumulation of the pericardial fluid, most of them quite cumbersome. We present our experience with intrapericardial administration of cisplatin. There were 6 patients, and the primary tumor was breast carcinoma in 2, lung in 1, ovary in 1, mediastinal fibrosarcoma in 1, and unknown in 1. Administration of cisplatin was virtually uneventful and painless, and there were no recurrences, with a survival of 2 to 18 months (mean 5.6).We conclude that intrapericardial cisplatin is safe and effective in treating malignant pericardial tamponade and preventing recurrence.

Because primary tumors of the heart in infants and children are extremely rare, most knowledge is based on collections of case reports rather than large cohort studies. The types of heart tumors encountered in the pediatric age group differ from those seen in adults. In the latter, cardiac myxomas are by far the most common tumor; in infants and children the most common primary tumor of the heart is the rhabdomyoma. Spontaneous regression of these tumors has been well established so that surgical intervention is no longer indicated unless there are clinical manifestations from the heart. There is a high incidence of associated tuberous sclerosis. Any intracavitary mass in infants is suggestive for a cardiac rhabdomyoma unless otherwise proven. The second most common tumor in this age group is cardiac fibroma. These tumors probably represent hamartomatous lesions and this has led to a strategy in which radical surgical excision is not indicated if the procedure endangers postoperative heart function. Cardiac myxomas are of interest in this age group because of their familial occurrence as part of the myxoma syndrome. Other types of primary heart tumors occur, including malignant variants, but all are exceedingly rare. It is because of the sporadic nature of these tumors that treatment and insights into prognosis are based largely on case documentations and analogies from similar tumors originating elsewhere.

Papillary fibroelastomas are rare, benign, primary cardiac tumors. They are, however, the most common primary tumor of the cardiac valves and may cause great morbidity risk from embolization. This paper reports the case of a healthy 34-year-old man who presented with symptoms of a right occipital embolic stroke. Transesophageal echocardiography revealed a papillary fibroelastoma on the anterior leaflet of the mitral valve. The papillary fibroelastoma was surgically excised and he has had no recurrent symptoms. This case illustrates the importance of obtaining a transesophageal echocardiogram to investigate a possible embolic source in patients with ischemic stroke.
