The consequences of pregnancy, abortion or tubal ligature were studied in 11 @entity1 with the @entity6924 . Seventeen cases of pregnancy and 7 tubal ligatures were reviewed. In the 4 pregnancies continued of term and preceded by cardiac catheterisation, there were two maternal @entity204 on the 2nd and 7th day of the postpartum period due to @entity1151 confirmed in one case and suspected in the other. A third pregnancy was complicated by @entity999 and one case of tubal ligature was complicated by non-fatal @entity1151 . These cases were compared with previous reports in the literature to form a total of 42 cases of pregnancy in @entity1 with the @entity6924 . The pregnancies were characterised by aggravation of dyspnoea and @entity848 in 72.4 p. cent of cases, by documented @entity1151 in 7 cases and by toxaemia of pregnancy in 26 p. cent of cases. The global mortality was 36 p. cent and all @entity204 but one occurred between the time of labour and the 11th postpartum day. Micro @entity358 were the commonest cause of @entity204 . Two mechanisms seem to combine to aggravate the cardiac status at the end of pregnancy and during the initial postpartum period: increased right-to-left shunt due to a rise in pulmonary resistances, due particularly to changes in coagulability favored by pregnancy; increased right-to-left shunt due to a decrease in systemic vascular resistances. A number of poor prognostic factors were identified: decreased @entity26 saturation in arterial blood and toxaemia of pregnancy.(ABSTRACT TRUNCATED AT 250 WORDS)
