Prognostic value of the electrocardiogram in endocardial fibroelastosis.

Nine children with endocardial fibroelastosis were followed from the time of admission with congestive heart failure until either death or discharge. Review of multiple clinical features showed that only the electrocardiographic pattern could be correlated with death or survival. The presence of a delayed transition zone with anterior force loss on the initial electrocardiogram ('infarct pattern') was noted in all the children who died. Progression of these changes with a pattern of anterolateral 'infarct' in two and inferior wall 'infarct' in two occurred before death. Necropsy on three of the four children confirmed the diagnosis of endocardial fibroelastosis. There was extensive fibrosis and thinning of the left ventricular myocardium as well as involvement of the mitral valve structures. Review of published cases supports the view that an 'infarct' pattern in a child with endocardial fibroelastosis is usually associated with death and that this pattern is a negative prognostic sign for survival.

Endocardial fibroelastosis in infants with hydrops fetalis.

Endocardial fibroelastosis, defined as an endocardium in excess of 30 microns thick, was found in 10 out of 34 cases of hydrops fetalis in a review of 1589 perinatal necropsies carried out between 1976 and 1989. The infants comprised 16 cases of rhesus haemolytic disease, of whom three had endocardial fibroelastosis, and 18 cases of non-rhesus hydrops, of whom seven had endocardial fibroelastosis. Intrauterine congestive heart failure was thought to have been the probable cause of hydrops in eight of the 10 infants with endocardial fibroelastosis. None of an age matched control group without endocardial fibroelastosis had evidence of congestive cardiac failure. These observations support the hypothesis that endocardial fibroelastosis is an endocardial response to chronic prenatal myocardial stress.

Ultrasonic studies on endocardial fibroelastosis.

Four patients with endocardial fibroelastosis were studied by two-dimensional and M-mode echocardiography. The two-dimensional echocardiography showed the characteristic echo from the abnormally thickened endocardium of the left ventricle in every case. Of the 4 cases, 2 were still suffering from congestive heart failure at the time of the study and the other 2 had been already free from clinical symptoms. In the former group, the ultrasonic findings revealed an enlargement of the left ventricle (large left ventricular dimension index) and poor movement of the anterior mitral leaflet which was indicated by a decrease in the diastolic descent rate. The latter group presented almost normal findings concerning the above points. The ultrasonic method is thus proved to be very useful for the diagnosis and evaluation of clinical conditions in cases of endocardial fibroelastosis.

Coronary and endocardial fibroelastosis of the ventricles in the hypoplastic left and right heart syndromes.

In an autopsy material of 29 cases of the hypoplastic left heart syndrome coronary fibroelastosis was found in 1 case, endocardial fibroelastosis in 8 cases. Figures for 10 cases of the hypoplastic right heart syndrome were 6 cases of coronary fibroelastosis and 1 case of endocardial fibroelastosis. Age ranged from stillborn up to 11-1/2 months. Coronary and endocardial fibroelastosis seemed to be mutually exclusive localizations of congenital fibroelastosis since in our material they did not occur together in the same hearts. In hypoplastic right hearts coronary fibroelastosis was either restricted to the right coronary artery (right circumflex and posterior interventricular branch), or it was found also in the left coronary artery (anterior interventricular branch), with the most serve affections always being situated in the right one. In the only case of coronary fibroelastosis among the hypoplastic left hearts the condition was limited to the anterior interventricular branch of the left coronary artery which communicated with the hypoplastic left ventricle by a fistula. Coronary fibroelastosis was exclusively found in branches supplying the hypoplastic right ventricle and/or in a branch connected by a fistula to the hypoplastic left or right ventricle. Endocardial fibroelastosis was generally found in hypoplastic left ventricles with either no outflow or with severe outflow obstruction. A theory concerning the aetiology of both coronary and endocardial fibroelastosis of the hypoplastic ventricles is proposed. It is argued that development of fibroelastosis may in both localizations be caused or favoured by the coincidence of two factors: abnormal haemodynamic conditions and poor oxygenation of blood and tissues. Observations made in a reference material of 35 hypoplastic left and 24 hypoplastic right hearts were in accordance with this view.

Heredity in primary endocardial fibroelastosis.

Twenty-six cases of endocardial fibroelastosis were collected from three hospitals in Manchester over a ten-year period. Nine cases occurred in 4 families and these are discussed in detail. X-linked recessive inheritance seems likely in one family in which two probable female carriers had subarachnoid haemorrhages. In a second family an apparently normal man produced two children with endocardial fibroelastosis by different mothers suggesting autosomal dominant inheritance with incomplete penetrance. Autosomal recessive inheritance may be involved in the remaining two families but this was not associated with consanguinity. Genetic heterogeneity is evident in endocardial fibroelastosis and the majority of cases occur sporadically. An accurate family history is therefore necessary but it is difficult to give precise recurrence risks in sporadic cases.

[Endocardial fibroelastosis in children to one year of age].

Out of 2398 autopsies of newborns and infants performed between 1976 and 1985, thirty two cases of endocardial fibroelastosis were found, i.e. 10.6% of the congenital heart diseases in this age group. Endocardial fibroelastosis was most frequent (44%) in infants aged between 3 and 6 months. Seventeen cases of the disease were seen in male infants and 15 cases in female infants. Twenty cases of the endocardial fibroelastosis (62.5%) were of isolated character (primary) whereas 12 cases (37.5%) were of the secondary character associated with other heart abnormalities. Nine cases (about 28%) coexisted with congenital abnormalities of joint and bone system and respiratory tract. A morphologic analysis of the endocardial fibroelastosis with particular reference to its etiopathogenesis suggest its congenital origin or (and) an effect of infection on myocardium. It was also suggested that endocardial fibroelastosis may be a symptom of collagenic disease. About 70% of autopsied infants were hospitalized over 3 days what meant that the course of the disease was severe. Endocardial fibroelastosis was diagnosed clinically only in 6 cases (18.75%).

Immunohistochemical study on human atrial natriuretic polypeptide in the ventricle of hearts with endocardial fibroelastosis.

The presence and distribution of human atrial natriuretic polypeptide (ANP) were investigated immunohistochemically in the ventricles of hearts of 14 cases with endocardial fibroelastosis and 15 cases with noncardiac disease in children. Paraffin sections of autopsied hearts with endocardial fibroelastosis were stained with polyclonal antibodies against human alpha-ANP. Immunoreactive myocytes were clearly demonstrated in the ventricles of 10 hearts with endocardial fibroelastosis. The distribution of ANP-positive cells was most frequent in the inner one-third of the left ventricle. No ANP immunoreactivity was detected in any heart in cases with noncardiac disease. The left ventricular volume index of hearts with ANP-positive cells was larger than that with ANP-negative cells. The mean diameter of ANP-positive myocytes was greater than that of ANP-negative myocytes. These results suggest that ANP expression in ventricular myocytes is related to severe dilatation of the ventricular cavity and to development of myocardial hypertrophy in endocardial fibroelastosis.

Familial nonobstructive cardiomyopathy with endocardial fibroelastosis beyond infancy.

A 10-year-old boy with congestive heart failure died in five months in spite of comprehensive medical treatment. Autopsy showed patchy areas of endocardial fibroelastosis of the left ventricle. The sister of this patient had followed a similar course at 13 years of age with death within six months of the onset of congestive failure. Her postmortem examination also showed endocardial fibroelastosis. The clinical presentation of familial endocardial fibroelastosis in the preteen and teenage years is a rare event. Probably the endocardial fibroelastosis was secondary to a familial nonobstructive cardiomyopathy.

Left ventricular dysfunction in the fetus: relation to aortic valve anomalies and endocardial fibroelastosis.

OBJECTIVE: To examine the relation between a characteristic form of left ventricular dysfunction in the fetus and abnormalities of the aortic valve and endocardial fibroelastosis of the left ventricle. DESIGN: A retrospective study to examine the correlation between echocardiographic findings in the fetus and postnatal or necropsy findings. SETTING: Tertiary referral centre for fetal echocardiography. PATIENTS: Thirty fetuses showing a characteristic echocardiographic picture of left ventricular dysfunction. MAIN OUTCOME MEASURES: The relation between the prenatal echocardiographic features and the postnatal and necropsy findings. RESULTS: At presentation the size of the left ventricular cavity was normal or enlarged in all cases. The measurements of the orifice of the aortic root and mitral valve were either normal or small for the gestational age. The echocardiographic diagnosis made at presentation was critical aortic stenosis in all cases. At necropsy or postnatal examination the aortic valve was dysplastic and stenotic in 15 cases and the left ventricle had become hypoplastic in one of these. Aortic atresia was present in seven patients, three of whom had a hypoplastic left ventricle. In six patients the aortic valve was bicuspid although not obstructive. One of these patients had hypoplasia of the aortic arch and one had a hypoplastic left ventricle but in the remaining four patients endocardial fibroelastosis of the left ventricle was the only abnormality found. No follow up information was available in two. Of 26 patients for whom there was postmortem information, 24 had evidence of some degree of endocardial fibroelastosis of the left ventricle. Sequential observations showed that five cases developed into the hypoplastic left heart syndrome. CONCLUSIONS: This type of left ventricular dysfunction in the fetus is the result of an overlap of diseases, including primary left ventricular endocardial fibroelastosis, critical aortic stenosis, and the hypoplastic left heart syndrome.

[Endocardial fibroelastosis (E.F.) and its differential diagnosis].

The endocardial fibroelastosis (EFE) is the most frequent cardiomyopathy. This disease is characterised by endocardial hyperplasia due to proliferation of elastic and collagenous fibres. There are primary and secondary forms. Within the primary form, the infantile form is the most frequent and of greatest importance to the pediatrician. This form is more a syndrom than a distinct disease. It is a reaction of the endocard due to several noxes. Lately a possible viral etiology is being discussed e.g. Parotitis, Coxsackie or other viruses. Clinical criteria for diagnosis are: cardiomegaly, left ventricular hypertrophy seen in 97% in the ECG, the absence of a murmur (or a soft apical mumur) absence of cyanosis and absence of systemic disease. Differential diagnosis is mainly between fibroplastic parietal endocarditis (FPE), cardiovascular collagenosis (CC) and endomyocard fibrosis (EMF). In FPE thrombosis is frequent and typically there is eosinophilia. CC is found in South Africa and is characterised by edema and fibrinoid necrosis. MEF is present mainly in Uganda, Nigeria and South India, characterised by endocardial fibrosis, valve involvement and eosinophilia. The obstructive hypertrophic cardiomyopathy is characterised by a pronounced cardiomegaly, insufficient weight gain as well as dyspnea and cyanosis. Catheterization shows a gradient across one or both of the outflow tracts due to hypertrophic subaortic or subpulmonic stenosis. Therapy of EFE consists in treating the cardiac decompensation and according to the severity of the disease, in steroids.

[Endocardial fibroelastosis of the left ventricle in a patient with Alagille syndrome].

We present a case of a 6 week old infant with Alagille syndrome. Cardiological evaluation revealed peripheral pulmonary arterial stenosis and left ventricular endocardial fibroelastosis. While peripheral pulmonary arterial stenosis are typical for the syndrome this is the first case reported with endocardial fibroelastosis. Complex cardiac malformations may worsen the prognosis in Alagille syndrome. They require early diagnosis and therapy.

Dilated and contracted forms of primary endocardial fibroelastosis: a single fetal disease with two stages of development.

Left ventricular endocardial fibroelastosis was diagnosed by echocardiographic scanning in a fetus at 20 weeks' gestation. Repeated prenatal examination over the next 20 weeks' gestation showed the development of the left ventricle from a chamber with a dilated cavity to a small cavity with a very thick wall. These findings were confirmed at necropsy and by the absence of other morphological anomalies. The contracted form of primary fibroelastosis in the fetus must have followed an insult that prevented any further increase in the size of the left ventricular cavity.

Endocardial fibroelastosis with coronary artery thromboembolus and myocardial infarction.

We report a case of an 18-month-old male, born to a woman with third trimester febrile illness, who had a history of congestive heart failure and respiratory distress, cardiomegaly, and electrocardiographic (ECG) findings suggestive of cardiomyopathy and myocarditis. After gradual improvement in heart size and function with pharmacologic therapy, he developed a terminal episode of respiratory distress and cardiogenic shock, with ECG findings of an anterolateral infarct. At autopsy it was found that endocardial fibroelastosis with mural thrombi in the left ventricle had been complicated by thromboembolism to the left anterior descending coronary artery, resulting in transmural infarction of the anteroseptal region of the left ventricle. Myocardial infarction is a potential but unusual thromboembolic complication of endocardial fibroelastosis. A high index of suspicion for coronary artery thromboemboli should be maintained in pediatric patients with cardiomyopathy and suspected myocardial infarction.

Ulnar agenesis and endocardial fibroelastosis.

We report on an infant with bilateral ulnar agenesis, radial hypoplasia, oligodactyly, hydrops fetalis, and endocardial fibroelastosis (EFE). The presence of the 2 major malformations and parental consanguinity suggests the possibility of a new autosomal recessive MCA syndrome.
