Pregnancy outcome
Since assisted vaginal delivery was construed as the most ideal
outcome for both mother and baby, pregnancy outcome was
arbitrarily classified in descriptive terms, namely, good, satisfactory
and poor; taking into account the mode of delivery and
the foetal outcome as follows: good outcome − vaginal delivery,
no maternal/foetal adverse effects; satisfactory outcome − C/S
performed with no maternal/foetal adverse effects; and poor
outcome − maternal and/or foetal adverse effect, irrespective of
mode of delivery. The overall pregnancy outcome was satisfactory
(Table 4).
In the native valve and prosthetic valve groups, only 21/77
(27%) patients had a good outcome, illustrating the significant
morbidity associated with these valve lesions. Patients in the
mitral regurgitation group had a much better outcome than
the other groups. In the congenital and myocardial group, the
number of patients in each category was almost equal.
