RESUMO
We present an example of right ventricular cardiomyopathy, a very uncommon condition which caused sudden death in an adolescent boy. This case report is used to highlight the pathological features of this rare and poorly understood condition, which is often undiagnosed (AU)

A total adult African population of age 16 years and over is being assessed for cardiovascular risk factors. Mean body mass index of the 303 men was 26.5 and that of the 465 females, 31.0. Hypertension was present in 19.0 per cent of women (89/465). Diabetes was present in 7.9 per cent men (24/303), 11.0 per cent women (51/465). Preliminary data reveal that ECG left ventricular hypertrophy, MACPC display using a modified Sokolow and Lyon Index (ECGLVH) is common: it is present in 27.4 per cent of men (83/303) -9.7 per cent of women (45/465). Results of echocardiograms are available on 198 men and 321 women. Males with ECGLVH had a higher mean of left ventricular wall thickness in diastole (p 0.025) and a higher mean of intraventricular septal thickness in diastole (IVSD) (p 0.05). Females with ECGLVH did not have a higher mean of LVWD or IVSD. LV mass was calculated by the criteria of Devereux and Reichek (1976). Mean left ventricular mass (LVMASS) was higher in respondents with ECGLVH both for males (p 0.05) and for females (p 0.05). Mean LV mass increased across the ten year age groups from 25 - 64 years both sexes (p 0.05). Mean blood pressures of respondents without LVH for males were 111.4/69.5, for females were 118.8/69.5. Further research into the factors affecting LV mass in this population are underway (AU)

Two unusual cases of triventricular hearts are described in which the right ventricle is partitioned into two chambers, the smaller of which is placed antero-superiorly and gives off the pulmonary trunk. Other anomalies present are high interventricular septal defect, overiding aorta and biscuspid pulmonary valves. Only a few cases of this anomaly appear to have been described. The possible pathogenesis is discussed and its relationship to Fallot's tetralogy is considered.(AU)
