Fetal activity in pregnancies complicated by rheumatic heart disease.
Severe cardiac disease in pregnancy may be complicated by reduced placental perfusion and subsequent fetal deprivation. In the present study we have evaluated one fetal parameter that may thus be affected, namely fetal activity. The study group included patients with rheumatic heart disease: 36 women with mild and 5 with severe disease. Each counted fetal movements 3 times a day and from this the daily fetal movement recording was calculated. One hundred and twenty women with normal pregnancies were the controls. The mild cases had fetal activity which was similar to that of the controls. The severe cases had reduced fetal activity, which was significant statistically at 29 to 32 weeks of gestation. Three in the severe disease group had marked decrease of fetal movements on admission to hospital. A return to normal fetal activity was observed following improvement of the maternal cardiac state. As was previously suggested for other high and low risk pregnancies, the maternal perception and counting of fetal movements may aid the fetal surveillance of patients with rheumatic heart disease.
