In the present study, the incidence of pregnancy complicated by heart disease was 0.43 %. Rheumatic
heart disease was the commonest aetiological factor, followed by congenital heart disease. Mitral stenosis was
the most common lesion among the Rheumatic heart disease group and atrial septal defect among the congenital
heart disease group. NYHA classes I and II had better prognosis than class III and IV. Maternal mortality was
6%. We conclude that pregnancy outcome is good in booked cases with regular checkup by obstetrician and
cardiologist, surgically corrected cases and those with NYHA class I and II. Hence, joint management by
obstetrician, cardiologist, anesthetist and neonatologist will go a long way in ensuring a good prognosis among
the pregnant patients with heart disease. In the present study, maximum number of women went into failure in
the third trimester, followed by four cases in the puerperium, two patients each in second trimester and during
labor. It has been customary to emphasize the time of maximum occurrence of cardiac failure in pregnancy. The
above observations show that failure can occur at any time during pregnancy or in the puerperium. Hence,
constant vigilance is required throughout antenatal, intrapartum and post partum period.
