[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.
