108 women with congenital heart disease in child-bearing age (16-38 years, mean age 28) were followed up for a period of ten years. Possible complications of contraceptive methods, and incidence of full-term pregnancies, spontaneous abortions and cardiovascular complications during pregnancy and delivery, were considered. Half of these patients had a cyanotic congenital heart disease, 23 had left-to-right shunt mainly at atrial level, 18 had right and 14 left ventricular outflow tract obstruction. 60 women had previous surgical procedures for their congenital heart disease. 83% of the patients were in NYHA functional class I-II. No complications were found during oral contraceptive regimen during intrauterine device insertion with antibiotic prophylaxis, except for the development of pulmonary hypertension in one patient with an atrial septal defect. 146 pregnancies occurred, but only 89 were full-term. There was a high number of interrupted pregnancies, rarely for medical reasons. The incidence of spontaneous abortion was similar to that of normal population (18% versus 10-15%). Maternal cardiovascular complications were found in the 22% of the full-term pregnancies, but were well controlled by medical treatment. In conclusion, good family planning and pregnancies are possible in most young females with congenital heart disease. In the absence of cyanosis and pulmonary hypertension, oral contraception does not carry any particular risk. With appropriate medical care intrauterine devices may be an alternative in high risk patients. In the presence of a good cardiac function, a normal full-term pregnancy with an healty baby is the rule. A cesarean section is seldom needed.

Abstract
108 women with congenital heart disease in child-bearing age (16-38 years, mean age 28) were followed up for a period of ten years. Possible complications of contraceptive methods, and incidence of full-term pregnancies, spontaneous abortions and cardiovascular complications during pregnancy and delivery, were considered. Half of these patients had a cyanotic congenital heart disease, 23 had left-to-right shunt mainly at atrial level, 18 had right and 14 left ventricular outflow tract obstruction. 60 women had previous surgical procedures for their congenital heart disease. 83% of the patients were in NYHA functional class I-II. No complications were found during oral contraceptive regimen during intrauterine device insertion with antibiotic prophylaxis, except for the development of pulmonary hypertension in one patient with an atrial septal defect. 146 pregnancies occurred, but only 89 were full-term. There was a high number of interrupted pregnancies, rarely for medical reasons. The incidence of spontaneous abortion was similar to that of normal population (18% versus 10-15%). Maternal cardiovascular complications were found in the 22% of the full-term pregnancies, but were well controlled by medical treatment. In conclusion, good family planning and pregnancies are possible in most young females with congenital heart disease. In the absence of cyanosis and pulmonary hypertension, oral contraception does not carry any particular risk. With appropriate medical care intrauterine devices may be an alternative in high risk patients. In the presence of a good cardiac function, a normal full-term pregnancy with an healty baby is the rule. A cesarean section is seldom needed.
