A 28-year-old woman was admitted to hospital during her
28th week of pregnancy complaining of dyspnoea.
Her symptoms had become increasingly more debilitating over a
period of eight weeks. On the day of admission she felt dyspnoeic
at rest, and was unable to lie flat.
There was no past history of note, other than an admission for
repair of a dislocated lens two years previously. This was her
first pregnancy. Urine dip-stick was negative for protein.
In-patient investigation culminated in cardiac catheterisation,
