This is a good informative article on how CHD's and small children waiting for transplants are driving research in new Ventricular Assist Devices (VADs) that will work for smaller children. Bean was once a candidate for having to go on the Berlin Heart, a VAD that is not fully approved by the FDA, but is often given a "compassion" waiver to be used on smaller children because there are no alternatives in the U.S. at this point. Luckily, Bean improved before that happened - but other children need options available and this research is a hopeful look at some options. There are some links at the bottom for more information on the NIH program for devices as well as NIH information on CHDs.
