Catheter ablation of supraventricular tachycardia without fluoroscopy during pregnancy.

Background: Although uncommon, supraventricular tachycardia is difficult to manage during pregnancy. Catheter ablation traditionally has been deferred owing to radiation exposure risks. Three-dimensional mapping is a new tool in cardiac electrophysiology, which is being utilized to eliminate fluoroscopy during catheter ablation.

Comparison of estimated fetal weights using volume and 2-dimensional sonography and their relationship to neonatal markers of fat.

Objective: The purpose of this study was to compare the accuracy of traditional 2-dimensional sonographically estimated fetal weight (EW2D) with 3-dimensional volume-based estimated fetal weight (EW3D) and to evaluate the relationship between fetal limb volume, birth weight, and markers of neonatal adiposity.

Methods: Fifty singleton pregnancies at 32 to 42 weeks' gestation underwent sonographic evaluation within 48 hours of delivery. We compared the accuracy of the EW2D and EW3D in the prediction of birth weight.

The impact of maternal obesity on satisfactory detailed anatomic ultrasound image acquisition.

Objective: To assess the impact of maternal body mass index (BMI) on ultrasound visualisation of fetal morphology.

Study Design: Singleton pregnancies undergoing targeted ultrasound fetal anatomic evaluation at 18- to 25-weeks gestation from 1/05 to 12/05 were included. Ultrasound reports and maternal medical records were reviewed for maternal characteristics and documentation of adequatecy of ultrasound visualisation for each organ system was obtained by individual chart review.
