Abstract: Heart disease complicating pregnancy is an important indirect cause of maternal mortality. The
present study aims to know the prevalence, aetiological factors, type of lesion, maternal and fetal outcome
in pregnancies complicated by heart disease. The prevalence in the study period was 0.43 %. Rheumatic
heart disease was the commonest aetiological factor, followed by congenital heart disease. Mitral stenosis
was the commonest lesion is the rheumatic group and atrial stenosis was the commonest lesion in the
congenital group. Maternal and fetal outcome was good in the NYHA functional class I and II and
guarded in the class III and IV . Maternal deaths were 6% in the series and all of them happened in
unbooked, previously undiagnosed cases coming to the hospital for the first time in labor or in cardiac
failure
