Furthermore, differences in age at conception probably
relate to earlier pregnancy with its attendant morbidity in poor
countries. In this study, 54% of the patients were ≤ 25 years old,
compared to a recent Canadian study where the mean age of
patients was 32 years.10 Not only were the study patients younger
at presentation for maternity care, but the initial detection
of cardiac disease was made during pregnancy in 27 of the 95
patients, 17 of whom had valvular heart disease. Isolated mitral
stenosis was present in 10 of these newly diagnosed ‘cardiacs’
(45.5%), similar to our previous report in which new cases of
mitral stenosis accounted for 42% per year of the total number
studied over a four-year period.5
This suggests that the incidence
of mitral stenosis in our society has not changed; the condition
is asymptomatic early in its natural history and is diagnosed
when the majority of women are medically examined only
