ABSTRACT: Many fellowship programs in maternal-fetal medicine (MFM) lack sufficient exposure and training in chorionic villus sampling (CVS). We describe a novel training model of transabdominal and transcervical CVS.
A porcine heart simulated a 12-week human uterus with a cervical canal created at the apex of the heart. A piglet was placed within a water-filled condom, which was placed inside the "uterus." A second water-filled condom simulated a maternal bladder. Fresh human placenta was placed between the condom and uterine wall. A zipper-sealed freezer bag with ultrasonic gel simulated an abdominal wall. Transabdominal ultrasound was utilized with this model to perform CVS.
The design involved four MFM specialists and three fellows. Twenty-three faculty MFM specialists and eight MFM fellows endorsed the fidelity of both models. One hundred percent of attendees of a procedural workshop agreed that these models could be used to teach proper technique to fellows and faculty.
We report a novel training model for transabdominal and transcervical CVS to teach proper technique in a nonclinical setting.
