[Circadian rhythm of blood pressure in patients with chronic hypertension and pregnancy].

Background: Ambulatory blood pressure monitoring during 24 hours shows a blood pressure variability. The prevalence of chronic hypertension in pregnant women is 1-5%, so it is important to know the changes in blood pressure and cardiovascular risk and prevent complications to the mother and fetus.

Objective: To know the circadian rhythm of the blood pressure in the chronic hypertensive pregnant patients, through the ambulatory blood pressure monitoring.

[Pregnancy and tetralogy of Fallot with and without surgical correction].

Background: Tetralogy of Fallot is the most common cyanotic congenital cardiac lesions. Although pregnancy in patients with corrected tetralogy of Fallot usually have a satisfactory outcome, there may have maternal cardiovascular complications.

Objective: To report our experience in monitoring and treatment of 16 pregnancies in 14 women with tetralogy of Fallot.

[Cardiovascular risk factors in climacteric].

Background: Ischemic heart disease is the second leading killer of women in Mexico, regardless of age group. The incidence of cardiovascular events increases after menopause, and depend on the prevalence and accumulation of risk factors.

Objective: To determine the prevalence of cardiovascular risk factors in a population of Mexican women who receive care in a menopause clinic.

[Pregnancy in patients with single ventricle, corrected and uncorrected].

We describe two cases of pregnancy in women with congenital heart disease, single ventricle. The first one underwent Fontan surgery at the age of 5 years due to a single ventricle of the left ventricular morphology. The second one, had uncorrected single ventricle.

[Ebstein anomaly and pregnancy].

Background: The Ebstein's anomaly is a congenital malformation of the tricuspid valve and of the right ventricle that usually is associated with interauricular communication, foramen oval, and arrhythmias of Wolff-Parkinson-White syndrome type.

Objective: To analyze the association between Ebstein's anomaly and pregnancy.

Patients And Methods: A prospective study was made in five pregnant women's with Ebstein's anomaly without surgery.

[Chronic high blood pressure in 110 pregnant women].

Background: Hypertension is associated with increased maternal and fetal mortality and morbidity. While there is consensus that severe hypertension should be treated, antihypertensive treatment for mild chronic hypertension during pregnancy remains controversial.

Objective: To evaluate clinical course, and maternal and perinatal outcomes of pregnant women with mild chronic hypertension without other disease, under strict control of maternal hypertension (target dBP of 85-89 mmHg).
