Pregnancy and delivery prognostic risk score for women with congenital heart disease and acquired valvular heart disease.

Hemodynamic changes related to pregnancy in women with Congenital Heart Disease (ConHD) or Acquired Valvular Heart Disease (AVHD) require special medical care during pregnancy and especially immediately prior to, and after delivery. Following a five year retrospective study (1978-1982), the authors monitored prospectively over a period of 12 years (1983-1994), 378 pregnancies in 252 women with ConHD and AVHD. Based on the results of the initial clinical examination and monthly follow-up visits, a numerical risk score was assigned for each patient. The study showed good conformity between the predictive risk score values and the patient's condition in the course of pregnancy and delivery. Thus, this method represents a novel and potentially very useful clinical tool for management of pregnancy in patients with ConHD and AVHD.
