Thirteen clinical charts belonging to children with Kawasaki disease admitted to different hospitals were analyzed. The average age among the children was three years (from nine months to nine years), with a predominance of this disease in males with a ratio of 3.3:1. Echocardiograms were obtained from 10 of the patients; seven showed coronary aneurysms (70%). Other complications seen were myocarditis in six children, and one case in each of the following: arthritis, pericarditis, cardiac failure, coronary thrombosis, hydropic gall bladder and aseptic meningitis. All of the patients recovered successfully; only four of the patients with aneurysms were followed-up with an echocardiogram. The echocardiogram showed the aneurysms to have disappeared in three of the children one to five months later, and the other showed a persistent aneurysm plus dilated myocardiopathy 2.5 years later in the remaining patient. It is worth noting the high incidence of aneurysms (70%) compared to other series (20-65%) which may be due to the suspicion of this diagnosis in only typical cases.

In this study from two specialized centres 85 patients with histologically proven myocarditis (n = 10) and clinically ascertained perimyocarditis (pericardial effusion and cardiomegaly or segmental wall motion abnormality; n = 75) were followed up for 4.5 + 1.9 years. Immunosuppressive treatment was not applied. After a mean follow-up period of 4.5 + 1.9 years 55% of patients had improved clinically and 35% of patients were completely free of symptoms. Relapses had occurred up to three times. Chronic forms were found in 20% of patients, mostly in those with pericarditis and effusions. Eighteen percent of the patients deteriorated gradually. In 20% of the chronic or deteriorating patients congestive heart failure developed (postmyocarditic heart muscle disease). Fifteen percent of the patients died, mainly from bacterial perimyocarditis and to a lesser extent from inflammatory heart disease from enteroviruses. Patients who succumbed after more than 6 months died either suddenly or from progressive heart failure. A favourable outcome was often accompanied by a decrease in titre, but this decrease was less impressive in those who had antimyolemmal and antisarcolemmal antibodies. The persistence of these antibodies in high titres predominated in patients with poor prognosis and postmyocarditic dilated heart muscle disease, as did cytolytic serum activity.

A 54 year-old man, who had a hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu disease; O-W-R) accompanied by pulmonary arteriovenous fistulas (PAVFs) and congestive heart failure, developed seizure, right hemiparesis and dysphasia. A brain CT scan revealed a cystic lesion with perifocal edema in left frontoparietal lobe. A contrast enhanced CT scan showed a ring-like enhancement. Dynamic CT scans disclosed that the ring in the cortical side was enhanced more thickly than that in the ventricular side. Considering the severity of the cardio-pulmonary condition, and the deep location of the abscess, we performed an echo-guided aspiration and drainage of the abscess under local anesthesia. No bacteria were demonstrated in the culture of the contents of the abscess. After the surgery, the right hemiparesis and dysphasia were much improved and a CT scan showed the marked reduction of the abscess. However, around eight days after the surgery, the patient showed severe pleural effusion due to progressive heart failure and died on the 11th postoperative day. Autopsy disclosed a shrunken brain abscess, multiple cerebral infarction, multiple PAVFs and severe constrictive pericarditis which was regarded as the cause of death in the patient. In this report, we presented the therapeutic advantage of echo-guided surgery for the treatment of brain abscess in a high-risk patient. We also discussed the mechanism of the formation of brain abscess in patients of O-W-R disease by reviewing published cases.

105 North American and European cases of Lyme carditis, being documented and in part published in the period 1977-1990, are reviewed and compared. The male: female ratio was 3:1, as well in Europe as in the USA. Transient atrioventricular block is the most frequent manifestation of Lyme carditis, with a remarkable similarity in the frequency of complete AV block and attending neurological illness in Europe and the USA. The distribution of (maximal observed) atrioventricular block in all patients existed of 49% third degree, 16% second degree and 12% first degree. Data of electrophysiological studies show that affection of the cardiac conduction system can be local or very diffuse. Other manifestations like rhythm disturbances, (myo)pericarditis and heart failure were less striking and have a less similar frequency in the European and American cases. Medicational therapy seems not to be an unconditional requirement for recovery of Lyme carditis itself, but cannot be withheld because of the proven beneficial effects of antibiotic therapy in other manifestations of Lyme borreliosis. Temporary pacemakers are frequently inserted, but pacemaker implantation is rarely needed. The overall prognosis of Lyme carditis seems to be good, although delayed recovery has been described and possible late manifestations have been suggested.

The cause of severe right heart failure and of equal diastolic pressures in both ventricles (as seen in constrictive pericarditis) in a 56-year-old woman was suspected to be cardiac amyloidosis on the basis of findings in both the echocardiogram (biventricular hypertrophy) and the electrocardiogram (prominent Q waves, absent hypertrophy signs). The endomyocardial biopsy was at first unremarkable. But later, serial modified Congo-red staining unequivocally demonstrated amyloid deposits. In a second case, a 66-year-old man with global cardiac failure and echocardiographic pointers towards hypertrophic cardiomyopathy, was treated with verapamil, 240 mg daily. When this was not tolerated he was hospitalized. He, too, had prominent Q waves but no signs of ventricular hypertrophy. Cardiac amyloidosis was confirmed by biopsy. Both cases underline the special importance of echo- and electrocardiographic changes, taken together, in the diagnosis of cardiac amyloidosis.

In 1984-88 the authors examined in 813 subjects with the chest pain syndrome of varying aetiology (acute myocardial infarction, myocarditis, pericarditis, vertebrogenic algic syndrome, embolism of the pulmonary artery, patients lacking detectable organic causes of pain) the trend of myoglobin serum levels. They found significantly elevated values only in patients with myocardial infarction and myocarditis whereby the two diseases differ in particular as regards the shape of the curve of myoglobin values. In chest pain with another aetiology the myoglobin levels rose only rarely or not at all. From the differential diagnostic aspect it is particularly valuable that myoglobin was not elevated in any patient with embolism of the pulmonary artery and only very rarely in angina pectoris. Where in exceptional instances the myoglobin levels were elevated in patients with other investigated causes of chest pain, this increase was always due to another basic disease (right-sided cardiac failure, renal insufficiency, neuromuscular disease), whereby for these conditions prolonged persistence of the elevated serum myoglobin values was typical and the levels were never above 8 nmol/l.

Four male patients aged 32 to 42 years were followed up. The clinical picture of the disease was typical of dilated (congestive) cardiomyopathy with a subacute onset, development of pronounced heart failure; all the patients were found to have exudate pericarditis. All the men were of the same occupation; they worked at the hard alloy works at a bay of wet grinding in ethanol of metallic Co and hard alloy carbides. The content of Co in the air of the working premises exceeded the MAC and amounted to 7.8-10 mg/m3. Besides, 47 workers of the same occupation (90% of the number of persons engaged in making up powdered compositions of hard alloys) were examined in addition. 16 persons showed the signs of alcoholization, including 9 (out of 11) working at a bay of wet grinding. During the recent 20 years, no cases of respiratory occupational diseases were recorded at the bay. The cardiotoxic properties of Co manifest themselves after the preceding toxic exposures, among which the leading part is played by alcohol. Of the 4 patients, 3 developed the disease in the presence of alcoholism, in 1 patient, it was coupled with tuberculous intoxication. Marked tendency towards polycythemia and increase of the content of hemoglobin was a frequently occurring manifestation of Co action on the workers (rather than a sign of intoxication).

The overall cardiovascular mortality in patients with chronic renal failure is about 30 per cent of which 10 per cent is attributed to myocardial infarction. This prevalence led some workers to propose a hypothesis of "accelerated atherosclerosis" due to the hyperlipidaemia observed in 30 to 70 per cent of patients. However, the concept of accelerated atherosclerosis, which was based essentially on clinical studies, has been questioned. Pericardial effusion is a common complication of chronic renal failure and has been reported in over 62 per cent of patients in echocardiographic studies. There are many causes and symptoms are often mild; systematic echocardiographic examination of patients with renal failure undergoing haemodialysis has shown 32 per cent of pericardial effusions to be asymptomatic. There are two potential complications: cardiac tamponade and, lesser frequently, constrictive pericarditis. Cardiac failure is a common cause of death in patients undergoing long-term dialysis. The myocardial histological appearances are those of fibrosis, the etiology of which is not fully understood although the dialysis membranes and hypotensive episodes occurring during haemodialysis have been thought to play a role. Left ventricular hypertrophy and fibrosis may give rise to ventricular arrhythmias which could explain some of the cases of sudden death observed in patients with renal failure and often wrongly attributed to ischemic heart disease. Another form of myocardial disease which is observed later is characterised by an alteration of systolic function with left ventricular dilatation and hypokinesia and increased end diastolic pressures without an increase in left ventricular wall thickness. Valvular heart disease may also result from renal failure.(ABSTRACT TRUNCATED AT 250 WORDS)

Diastolic heart failure is characterized by increased resistance to diastolic filling of one or both cardiac ventricles. Although some degree of diastolic failure exists in most patients presenting clinically with heart failure, a substantial subset of patients have relatively pure diastolic heart failure with normal systolic function. Diastolic heart failure can be due to structural abnormalities that increase resistance to ventricular inflow, and these structural abnormalities can be extramyocardial (e.g., constrictive pericarditis and mitral stenosis) or intramyocardial (e.g., fibrosis and amyloidosis). In addition to structural abnormalities, physiological derangement of myocardial inactivation and relaxation can contribute importantly to diastolic dysfunction in patients with heart failure. There is mounting evidence that advanced myocardial hypertrophy is associated with increased resistance to ventricular diastolic inflow due to both structural alteration (increased wall thickness and altered collagen matrix) and impaired diastolic relaxation of the hypertrophied myocardium. Physiological mechanisms for impaired relaxation in advanced hypertrophy remain controversial but can include disordered function of myocardial sarcoplasmic reticulum, subendocardial ischemia, and altered adenylate cyclase function. Diastolic dysfunction can play an important role in the genesis of flash pulmonary edema seen in patients with ischemic heart disease because myocardial ischemia is associated with a decline in relaxation rate, increased resistance to early diastolic filling, and in some cases, a striking upward shift in the left ventricular diastolic pressure-volume relation.(ABSTRACT TRUNCATED AT 250 WORDS)

The pathologic study of the cardiac lesions in 25 persons who died of AIDS were studied from autopsies. Most of these patients were intravenous drug abusers (14 cases). Heart failure was symptomatic and lead to death in 4 cases. This study showed histological abnormalities in 76% of the cases. We observed 12 myocarditis. In 6 cases, pathogenes were found: Toxoplasma gondii (2), Cryptococcus neoformans (2), Candida (1), Aspergillus (1). A lymphocytic myocarditis was observed in 6 hearts. By immunohistochemical technique, we could distinguish 2 toxoplasmic myocarditis, and in 4 cases, solitary cysts in the myocardium without inflammation. The remaining lesions comprised respectively: 3 lymphocytic pericarditis, 2 marastic endocarditis and 1 dilated myocardiopathy.
