A case of chronic pericarditis with effusion in a 25 years old white man, 19 months after therapeutic irradiation of the mediastinum with a total dose of 4.350 rads for
Hodgkin's disease
. Pericardiectomy was followed by improvement of functional capacity persistent 7 months after operation.

To determine the incidence of pericardial effusion in patients undergoing upper mantle radiation therapy, 81 patients with
Hodgkin's disease
, stages I to IIIB, were selected from a protocol series of 98 patients. Twenty-four patients (29.6 percent) met X-ray criteria for the presence of pericardial effusion. Eleven of the 24 also underwent right heart catheterization to confirm the presence of pericardial effusion and to define any hemodynamic abnormality. Fourteen patients were found to have transient effusion. Five of the 11 patients have had partial pericardiectomy for symptoms and signs of cardiac tamponade. There has been no evidence of recurrent
Hodgkin's disease
in these surgically treated patients. Ninety-two percent of the pericardial effusions occurred in the first 12 months after the end of radiation therapy. Therapeutic implications depend on elucidation of the natural history of this process. At present close follow-up is necessary with surgical intervention for signs or symptoms of cardiac tamponade.

The case of a 45-yr-old man with constrictive pericarditis due to radiation for
Hodgkin's disease
is described. After pericardiectomy and clinical condition did not improve. At necropsy an extensive fibrosis of the myocardium especially located in the anterior part of the heart was found. The clinical consequences of this finding with respect to surgical treatment are briefly discussed.

A 32-year-old male with stage IIIA nodular sclerosing
Hodgkin's disease
and no cardiac risk factors presented with chest pain after receiving chemotherapy consisting of multiple drugs, including vinca alkaloids. He completed an uncomplicated anterior wall myocardial infarction. Coronary angiography documented the absence of significant coronary artery disease. Exercise stress testing with gated scan confirmed loss of anterior wall motion and a decreased left ventricular ejection fraction. Vascular toxicity, including, rarely, myocardial infarction, has been reported following antineoplastic regimens containing vinca alkaloids. Hypercoagulable states, cardiac invasion by tumor, and coronary artery spasm are possible etiologies. Of these, coronary artery spasm appears most likely. Management should include discontinuation of the offending drug and supportive care.

It is well known that radiation therapy to the anterior mediastinum may induce lesions of all cardiac structures. The pericardium is most frequently involved, but atrioventricular conduction disorders, cardiomyopathy, coronary stenosis may also be produced. Aortic, mitral and tricuspid lesions have been described. However, clinical evidence of pulmonic valve involvement has not been reported. Only at necropsy has fibrotic thickening of the pulmonic cusps occasionally been found. We report a case of infective endocarditis of the pulmonic valve in a 53-year-old patient who had undergone thoracic radiation therapy for
Hodgkin's disease
31 years previously. Four years prior to the endocarditis he had also been submitted to myocardial revascularisation for critical lesions of the left main and right coronary ostia, and to aortic valve replacement because of stenosis and insufficiency. At that time, the pulmonic valve was fibrotic on echo examination. It is noteworthy that, of all the cardiac valves, the infective process involved only the pulmonic one, which is seldom the target of an infection. To our knowledge this is the first case of bacterial endocarditis of a heart valve that had been previously damaged by radiation therapy.

The authors report the case of a 30-year old patient who presented atrioventricular block 12 years after mediastinal radiation treatment of
Hodgkin's disease
. This patient had been monitored in the service for 3 years after the insertion of a pacemaker. A review of the literature, identified 15 cases of post-radiation AV block. The AV block was subnodal in the 7 cases which were subjected to endocavitary recording.

Non-
Hodgkin
's lymphomas are frequent in patients with human immune deficiency virus positive antibodies. Exceptional instances of cardiac involvement have been described. We report a case of non-Hodgkin's lymphoma and massive cardiac involvement with antemortem echocardiographic assessment. Use of echocardiography in lymphomas-associated AIDS could help in discovering further cases of cardiac involvement.

We studied TTX-sensitive Na channels in dissociated single ventricular cells from neonatal rats using the patch clamp method for single channel and whole cell recording. In both cases, slowly inactivating or window currents were observed that decayed in a biexponential fashion. Customary models of Na current kinetics such as the
Hodgkin
-Huxley model attribute activation to a process that is much faster than inactivation. The model of Aldrich, Corey and Stevens(1), says that inactivation is fast and final and activation is dispersed. We found activation too associated, deactivation too quick, and reopenings too frequent to accept this model for cardiac Na channels. We also found that the predominant set of single Na channels had one open state and two inactivated states. Rarely, a second set of Na channels having about 2/3 the conductance and mean open time of the predominant set was found.

The sodium (Na) channel is the fundamental unit of excitability in heart muscle. This channel has been very difficult to study in detail, because the major experimental tool, the voltage clamp, has been difficult to use in multicellular tissue. In the absence of more direct studies in the heart, it has been assumed that the sodium channel in the heart was the same as that in nerve tissue, where it could be studied quantitatively. However, the sodium channel is not likely to be the same as in nerve, because it responds differently to local anesthetics and to other drugs such as tetrodotoxin. It is essential to learn the details of the cardiac sodium channel, because it is the membrane process that underlies many lethal cardiac arrhythmias, and it is the molecular site of action of the most effective antiarrhythmic drugs. Single cardiac Purkinje cells were dialyzed at room temperature through a large bore pipette, and their Na+ currents were studied under voltage clamp control. The peak currents were 0.5 to 1.0 mA/cm2, assuming a 1 mu farad/cm2 membrane. Peak currents near 0 mV were achieved in less than 1 ms. The decay of the Na+ current did not correspond to a single exponential process. This result and the observation that recovery from inactivation occurred with a latency are inconsistent with the original
Hodgkin
-Huxley model, but they qualitatively fit a model with two sequential inactivated states or a model with two kinetically different types of Na+ channels. The steady state inactivation curve shifted in the negative direction after initiation of intracellular dialysis, stabilizing with a half-availability voltage of -115 mV.

Coronary lesions are one of the complications of mediastinal radiotherapy; they are more uncommon, at least in their clinical expression, than the involvement of the pericardium, but they are interesting by their gravity and occurrence in young patients (35 years old, in an average). We are reporting 7 cases in addition to the 53 already recorded in the literature. The neoplasm which led to the radiation treatment is, in 85 p. cent of the cases
Hodgkin's disease
and in 10 per cent of the cases a breast cancer. The time of occurrence of the clinical signs is of 5 years, in an average. The revealing symptom is an initial necrosis or an angor, most often unstable (45 p. cent of the cases, for each of them), more exceptionnally it is a sudden death or a pericarditis. The coronary risk factors have been determined in 37 patients; 45 p. cent had none. In half of the cases, the coronary involvement is monotruncular and frequently proximal (the anterior interventricular trunk is affected twice as often as the right coronary); in the other half, there is an equal distribution between bi-troncular and tri-truncular involvement. There are various pathological lesions: typical with isolated fibrosis of the intima and aventitia, pure atherosclerotic lesions or association of the two. The prognosis of these coronary lesions is severe (43 p. cent of deaths), but the patients who underwent revascularization procedures (by-pass or more seldom transluminal angioplasty) have in 80 p. cent of the cases a favorable evolution.(ABSTRACT TRUNCATED AT 250 WORDS)
