[Total anomalous pulmonary venous return into the coronary sinus. Apropos of 1 case with a difficult diagnosis and surgical success].

The case of an 8 year-old boy with total anomalous pulmonary venous return into the coronary sinus is reported. The coronary malformation comprised a considerable dilatation of the coronary sinus which made diagnosis very difficult even at open heart. The surgical success was obtained by resecting the interatrial septum and partitioning the atrium. The anatomical diagnosis of this condition and the malformations with which it could be confused are discussed: TAPVR into the right atrium, cor triatriatum. The two parts of the coronary sinus, confluence of the cardiac veins and the left horn of the sinus venosus, are described.

[Post-partum myocardiopathy. Apropos of 25 cases].

The authors have studied 25 cases of PPC which were selected according to very strict criteria. These cases represent 1 case of PPC for every 2 687 confinements, and 37.8% of all cardiomyopathies in females of child-bearing age. The females with PPC belonged to the more deprived socio-economic population. Multiparity and twin pregnancies are predisposing factors. The clinical picture is usually one of biventricular of left heart failure. Four cases of embolism are included (16%, which is a high figure for Africa). The special investigations are important. Mechanographic studies show a very significant lengthening of the pre-ejection phase (especially QB1), and a reduced ejection phase; haemodynamic studies show in particular increased pressures on the right side in 4 cases out of 6. (3 of which had an arterio-capillary gradient). Angiocardiography, carried out in 4 cases, showed abnormalities especially of the left ventricle (especially dilation and hypokenesia). The outcome may be favourable, especially after 3 to 6 months have elapsed. However, complications may arise in the long-term (10, 14 and 37 months). There were two deaths (8%). Histologically, the lesions were mainly of a congestive type, with some areas of fibrosis, and rarely areas of inflammation (myocarditis). From the aetiological standpoint, it might be thought that during the posptpartum period, various abnormal conditions prevail or would be discovered (13 in our series); but it is also true that some cases of true PPC, with marked stasis and a tendency to thrombosis, as well as severe involvement of the myocardium (as witnessed especially by the mechanographic findings), to progress after 3 months either to resolution, death, or complications; the histological findings in the two fatal cases were of myocarditis.

[Study of 20 cases of apparently primary pulmonary arterial hypertension].

The authors have studied the clinical, electrocardiographic, radiological, phonomechanographic and haemodynamic features of 20 cases of apparently primary pulmonary hypertension of fairly severe degree. An attempt has been made to correlate on the one hand the haemodynamic values, and on the other the clinical findings, ECG signs of right-sided preponderance, the size of the artery to the right lower lobe on X ray, and the phonomechanographic results. Particular importance is given to a discussion on the aetiology. It is recalled that syphilis can be excluded, that it is possible the operate on thromboses, and that bilharzia and the haemoglobinopathies may play a part which is yet to be defined.

[Diagnostic significance of phono-mechanographic medication of constrictive endocardial fibrosis (or endomyocardial fibrosis)].

The phonomecanographic investigation of 12 patients with FEC allow us to recognize diagnostics signs of great interest. 1. The ventricular aspect of the jugular veinous pulse involving a positive systolic wave and a diastolic aspect in "dip-plateau" is a chief indication of a right ventricular fibrosis. This indication is more significant of FEC when the nadir of the dip is far above the base line, when the dip-rising time is short, when the telediastolic ratio is high (more important than 0.40) when the electro-mechanical latency time is prolonged and when the isovolumetric relaxation time is normal. 2. The apexogram aspect in diastolic dip-plateau is a capital indication for a fibrosis of the left ventricule. This indication is more significant when the nadir of the dip is above the baseline, when the telediastolic ratio is high (more important than 0.30) when the electromechanical latency time and the isovolumetric relaxation time are normal. 3. The protodiastolic endocardial vibrancy recorded during the dip climbing and showing the features we described, seems to us to be a very important sign. This vibrancy can be preceded or/and followed by a short and early diastolic murmur of low frequency, always finishing at the end of the dip. 4. Recording of pulmonary valves or atrio-ventricular murmur is an important diagnostic feature in an adiastolic syndrome. 5. Recording of a pulmoanry infundibular impulse is an indication for a right ventricular fibrosis. This indication is very significant if the tracing is a dip-plateau.

[14 cases of constrictive endocardial fibrosis (or endomyocardial fibrosis].

Constrictive endocardial fibrosis (CEF) or endomyocardial fibrosis (EMF) was studied on 14 files of this rather frequent disease in Ivory Coast. On the basis of the data derived from angiocardiography, catheterization and mechanograms, the clinical signs are interpreted better. Thus one is able to describe with accuracy some clinical forms, the commonest of which being a right heart restriction combined with left-sided signs. It seems important underline how useful the external pulse recordings might be useful for the diagnosis in view of their analogy with the pressure curves. In this disease with a severe course, bold surgical treatments provide some hope. On the contrary, its aetiology remains mysterious. Our best landmark being the link of CEP with tropical ecology, and in particular, in our cases, with the warm and damp forest ecology of some areas.

[Coronary diseases in the black African. Apropos of a 2d group of 50 patients. Diagnostic and epidemiological aspects].

1. Study of a group of 50 patients suspected to have coronary artery disease. This is a complement to a previous study concerning "definite" coronary patients. 2. The method followed consisted in cross-examination of the files by three observers in order to separate the subjects who seemed really affected by coronary artery disease. This treble examination led to a rather restrictive selection. To facilitate the study, the patients were subdivided into 4 groups: patients with arterial hypertension, with diabetes mellitus, with cardiac failure, with a heart disease and miscellaneous patients. 3. The study of the 20 files which were discarded was peculiarly interesting as it provided the opportunity to underline the differential diagnosis either with common diseases (left ventricular overload, heart block, brain vascular accident), or with more specific diseases for Black Africa (endomyocardial fibrosis, aneurysm of the left ventricle, cardiomyopathy). In that respect, it is underlined that, in the absence of any anatomical or functional disease, the electrocardiogram of the healthy Black is identical to that of the White. 4. Study of the 30 patients considered as coronary made it possible to underline aetiological and epidemiological factors, although some are still lacking. However the facts observed could be compared with those reported in a previous work concerning 45 "definite" coronary patients. The overall documents thus gathered in 75 patients suggest that the African candidate to coronary artery diseases resembles his Occidental homologue, but that he might have kept a traditional diet.

[Phonocardiographic and mechanographic study of 12 cases of constrictive endocardial fibrosis (or endomyocardial fibrosis)].

A phonomechanographic study of 12 patients with restrictive endomyocardial fibrosis (EMF) has highlighted the essential criteria for the diagnosis of this condition. The "ventricular" type of JVP, with a dip-plateau, is a reliable sign of right-sided EMF; this sign is more rarely of the tricuspid incompetence type. A similar picture emerges from recordings of hepatic pulsation, or other venous pulses. An apex-cardiogram with a dip-plateau is in favour of the diagnosis of left-sided EMF. The finding of a recordable infundibular impulse supports a left-sided EMF. Demonstration of an early-diastolic thrill, of endocardial origin, is an essential feature of this condition. It coincides with the rising phase of the dip, and was found in 10 of our 12 cases. There may also be murmurs arising from the pulmonary and atrio-ventricular valves. The characteristic feature of the carotid tracing is a prolonged pulse wave, with corresponding reduction of the haemodynamic quotient. These signs result from contraction of the potential filling space of the ventricle, from the restricted movement of the atrio-ventricular valves, and from a reduced blood flow.

[Systematic cardiologic study in 37 schistosomiasis patients].

1) A systematic search was made for cardiac abnormalities (clinical, radiological and EKG) and for haemodynamic disorders (catheterisation of the right side of the heart and pulmonary artery). It was generally found that: -- 14 patients (37.8%) had no symptoms; -- 8 patients (21.6%) had pulmonary arterial hypertension (PAHT) with the corresponding cardiac signs; -- 15 patients (40.5%) had cardiac signs with no evidence of PAHT. 2) The 8 patients with PAHT (21.6%) had precapillary type of PAHT with an arteriocapillary gradient. The symptoms were those of PAHT and of the right ventricular failure; but this desorder could be latent. PAHT can be in relation with inflammatory lesions. In these 8 patients, S. Mansoni was to blame in 6 cases and 5 S. Hematobium in 2. 3) In 9 patients (24.3%), cardiac signs were connected indirectly with bilharziasis by anemia, iatrogenic injury or hypertensive myocardial disease of renal origin. 4) In 3 patients (8.1%), cardiac signs were found because of coexistant disease. 5) In 3 patients (8.1%), cardiac signs could have been due to bilharzia myocarditis. The authors reviewed the experimental and clinical discussions for such a possibility.

[Heart and schistosomiasis (author's transl)].

The review is based on three studies previously reported and involving the clinical, epidemiological and hemodynamic aspects of this problem. Schistosomasis may give frequently (21.6 p. 100) an arterial pulmonary hyperpressure related to the development of granulomas and arteriolitis. A myocarditis may be suspected but is rarely proved. Anemia and specific treatment are also responsible for myocardial deficiency. The parasitic changes of the urinary tract may give a systemic hypertension. Some very rare cases of acute pulmonary heart insufficiency have been reported and the responsibility of schistosomiasis in constrictive fibrous endomyocarditis is still questionned.

[Clinical features of constrictive endomyocardial fibrosis (author's transl)].

Constrictive endomyocardial fibrosis is very frequent in tropical areas with a hot and rainy climate. Young patients and specially male ones are generaly concerned. The onset is gradual and low-giving an adiastolic condition which may prevail on the right or the left heart. Some periods of more acute evolution may be observed. Death is caused by adiastolic disorders, thrombosis or arythmia. Aetiology is still unknown. A surgical treatment may be considered in some cases.

[50 cases of acute malaria: symptomatic study, especially cardiac].

The authors have studied 50 records of patients who had presented an acute attack of P. falciparum malaria. Both sexes were equally implied. Young people were predominant. The distribution of cases was about the same in the whole year. The fever decreases on the second day and increases on the third day (300/0). Among the classical signs: relative rarity of hepatomegalia (100/0), splenomegalia (10 0/0), jaundice (140/0), nervous symptoms (100/0). Vomiting is rather frequent (30 0/0). From the cardiovascular point of view a relative bradycardia is observed in 16 0/0 of the cases, and a relative tachycardia in 100/0 of the cases; hypotension in 100/0 of the cases. Electrocardiographic signs are observed in 360/0 of the cases; they are aspecific, concerning mainly ST-T anomalias (22 0/0) and a QT lengthening (200/0). The cardiothoracic ratio is higher than 0.5 in 320/0 of the cases. From the pulmonary point of view the authors have observed symptoms contemporary of the attack: two asthma attacks, three radiologic anomalias reminding of viral pneumopathias. The biological symptoms are mainly transitory functional renal insufficiency in 18 0/0 of the cases. Protection due to AS heterozygosis seems to be confirmed in this study. The efficiency of intravenous quinin treatment is certain.
