Cardio-Obstetrics Team-Based Management of a Pregnant Patient With Severe Bioprosthetic Aortic Valve Disease.

A 38-year-old pregnant patient was managed by the cardio-obstetrics multidisciplinary team for severe degenerative bioprosthetic aortic valve failure. She was medically managed utilizing echocardiogram and brain natriuretic peptide until she demonstrated worsening heart failure. A valve and cardio-obstetrics team evaluation led to valve-in-valve transcatheter aortic valve replacement at 30 weeks' gestation.

Fetoscopy-Assisted Percutaneous Decompression of the Distal Trachea and Lungs Reverses Hydrops Fetalis and Fetal Distress in a Fetus with Laryngeal Atresia.

We present a case of prenatal hydrops secondary to congenital high airway obstruction syndrome (CHAOS) that was treated with fetoscopy-assisted needle decompression. A 22-year-old G3P2 woman presented after a 21-week ultrasound demonstrated CHAOS. The fetus developed hydrops at 25 weeks, characterized by abdominal ascites, pericardial effusion, and scalp edema.

Prenatal diagnosis of ring chromosome 6 in a fetus with hydrocephalus.

A patient with ring chromosome 6/monosomy 6 mosaicism is presented. At 25 weeks' gestation, ultrasound examination demonstrated fetal hydrocephalus. Amniocentesis was performed.

Pregnancy after mustard repair for transposition of the great arteries.

Background: Since the introduction of surgical repair procedures, women with complete transposition of the great arteries are surviving into their reproductive years. Only three successful pregnancies in such women have been described previously.

Cases: Three women with transposition of the great arteries repaired in childhood became pregnant in 1991.

Decrease in annexin I messenger ribonucleic acid expression in human amnion with labor.

Objective: Annexins are a superfamily of proteins that are thought to inhibit phospholipase A2 activity and hence inhibit prostaglandin production. The purpose of this study was to test the hypothesis that annexin I concentration in human amnion is reduced with labor and that this reduction is mediated by a decrease in annexin I messenger ribonucleic acid expression.

Study Design: Amnion and choriodecidua were collected from term singleton pregnancies, eight after spontaneous vaginal delivery and eight from elective cesarean section without labor.

Hepatitis C in obstetrics and gynecology.

Because of the risk of perinatal transmission and possible sexual transmission, it is important for obstetrician-gynecologists to keep abreast of the rapidly expanding literature on hepatitis C. Acute hepatitis C represents about 5% of all reported cases of hepatitis. Approximately 50% of acute infections progress to chronic liver disease.
