Summary

This study outlines a training method for transcervical chorionic villus sampling (CVS). Experienced physicians can master this prenatal diagnostic technique through progressive skill development and observation.

Area of Science:

Medical training
Prenatal diagnostics
Reproductive genetics

Background:

The Trophocan catheter's FDA approval in 1990 led to increased transcervical chorionic villus sampling (CVS) use.
Some states mandate specific CVS procedure numbers for physician credentialing, posing feasibility challenges.

Purpose of the Study:

To describe a training approach for reproductive genetics services performing transcervical CVS.
To ensure physician competency in ultrasound-guided invasive procedures for CVS.

Main Methods:

Physicians train in amniocentesis for ultrasound-guided needle skills.
Assistance with transabdominal CVS and gradual progression to transcervical CVS cases.
Observation at high-volume centers to learn common transcervical CVS pitfalls.

Main Results:

The described training method has been successfully used for over 5,000 CVS procedures.
Six reproductive genetics fellows have been trained in transcervical CVS using this approach.

Conclusions:

A structured training program, combining foundational skills with progressive complexity and observation, is effective for transcervical CVS competency.
This method facilitates physician training in a critical first-trimester prenatal diagnostic procedure.
