A 52 year old patient with no previous medical history had an attack of ventricular tachycardia, the configuration of which showed left sided delay. Electrical reduction was followed by multiple recurrences. There were ST-T wave changes over the right precordium on the basal ECG. The hydro-electrolytic equilibrium was normal. Coronary angiography and selective left ventricular cineangiography were also normal. Right angiocardiography showed an aneurysmal deformation of the pulmonary infundibulum. The recurrence of attacks over a two year period led to several hospital admissions, demonstrating the failure of antiarrhytmic therapy. The attacks became so frequent in the last three months that surgery was undertaken. Epicardial mapping showed delayed potentials over the pulmonary infundibulum and surgery consisted in resection of the abnormal infundibular zone. The macro- and microscopic pathological findings were of wall thinning and muscular degeneration with fibrosis and fatty infiltration. The authors discuss the relationship between right ventricular dysplasia and a localised form of Uhl's anomaly. Six years after surgery the patient has had no recurrence of the arrhythmia or shown signs of cardiac failure in the absence of any drug therapy.

A diastole is a non specific haemodynamic syndrome which may result from constrictive pericarditis or from a restrictive cardiomyopathy. The aim of this study was to differentiate these two types of condition by analysis of computerised M mode recordings of the left ventricle. Three groups of patients were studied: 5 cases of confirmed cardiac amyloidosis (Am); 5 cases of constrictive pericarditis confirmed surgically (CP) and 10 normal subjects (NL). The study was based on analysis of parameters of ventricular filling and of diastolic thinning of the LV free wall. A significant difference was observed between AM and CP but not between PC and NL. Amyloidosis was characterised by a reduction in the maximum velocity of endocavitary diameter lengthening (AM 0,84 +/- 0,56 cir/sec; PC 3,95 +/- 0,77, p less than 0,01), prolongation of the rapid filling phase (AM 0,42 +/- 0,17 sec; PC 0,16 +/- 0,06 sec, p less than 0,02) and a decrease in maximum velocity of free wall thinning (AM 0,45 +/- 0,23 th/syst/sec; PC 4,79 +/- 2,1, p less than 0,01). The diastolic thickness of the free wall was greater in the amyloidosis group (AM 1,73 +/- 0,61 cm; PC 1,05 +/- 0,21, p less than 0,05) and correlated with the reduction of maximum velocity of free wall thinning. Parameters of global diastolic filling did not distinguish the two conditions. The M mode recordings were therefore digitalised to provide graphs of chamber filling and wall thinning and their derivatives.(ABSTRACT TRUNCATED AT 250 WORDS)

In 16 cases of reflex sympathetic dystrophy of the knee, the authors obtained by drill biopsy 29 bone samples from the epiphyseal and metaphyseal regions of the femur and tibia and 8 cartilagenous samples (including 6 by arthrotomy and 2 after patellectomy). They noted thinning of the cortical bone, lacunae of cortical reabsorption, rarefaction of the trabeculae, of which some were dead, stasis and fibrosis of the bone marrow. The 8 cartilage samples were pathological, with, in particular, fibrosis of the surface cartilage (vascular pannus formation). The association of chondromalacia of the patella with an S.R.D. syndrome of the knee is frequent.

New indications have recently appeared for cardiac pacing with haemodynamic and antiarrhythmic objectives without any symptomatic bradycardia. The best documented indication, though relatively rare, is stimulation of obstructive hypertrophic cardiomyopathy; initially reserved for cases with favorable results of an acute haemodynamic test, it is now used in other cases without this criterion; hypertrophic cardiomyopathy without permanent obstruction, atrial fibrillation or left bundle branch block. The improvement observed during follow-up is always greater as a real remodeling of the myocardium seems to occur with ventricular dilatation and/or septal thinning. However, the position of the atrial, and above all, of the ventricular pacing catheters is critical as is regulation of the pacemaker which should allow complete ventricular capture with an AV delay allowing good filling. The follow-up of these patients must therefore be regular and the effects on longevity are unknown. DDD pacing has also been proposed in dilated cardiomyopathy. The results are contradictory and only very selected cases with left bundle branch block and long PR interval seem justified with, again, optimisation of the pacing sites with high septal or biventricular stimulation. Recurrent atrial tachycardia, special algorithms preventing extrasystoles have been tried with variable results. In cases with inter-atrial block, atrial resynchronisation by bi-atrial stimulation has been assessed with promising results but many technical problems remain unsolved.

Of the three physiopathological types of cardiomyopathy, dilated, hypertrophic and restrictive, it is the first which characteristically shows major left ventricular systolic dysfunction. The left ventricular volumes are increased, the ventricle becomes spherical and global ejection fraction decreases with diffuse or segmental wall motion abnormalities. The left ventricular mass is increased in an excentrical fashion with wall thinning. Isovolumic contraction is slower, the ejection time is shorter and, above all, the indices of contractility such as maximal velocity of the contractile elements ... are very abnormal and do not improve after positive inotropic stimulation.

The authors report a case of a 48 year old woman admitted to hospital because of digital ischemia, in a context of antiphospholipid syndrome. The electrocardiogram-triggered electron beam computed tomography revealed an apical thrombus associated with a thinning left ventricular wall, suggesting painless myocardial infarction. The diagnosis was secondary confirmed by coronarography.
