Testing an artificial intelligence algorithm to predict fetal heartbeat of vitrified-warmed blastocysts from a single image: predictive ability in different settings.

Study Question: Could an artificial intelligence (AI) algorithm predict fetal heartbeat from images of vitrified-warmed embryos?

Summary Answer: Applying AI to vitrified-warmed blastocysts may help predict which ones will result in implantation failure early enough to thaw another.

What Is Known Already: The application of AI in the field of embryology has already proven effective in assessing the quality of fresh embryos. Therefore, it could also be useful to predict the outcome of frozen embryo transfers, some of which do not recover their pre-vitrification volume, collapse, or degenerate after warming without prior evidence.
