AI Can Help Spot Congenital Heart Defects
By Dennis Thompson HealthDay Reporter
FRIDAY, Jan. 31, 2025 -- Artificial intelligence (AI) can help doctors detect fetal heart defects, improving newborns’ chances of survival, a new study says.
AI-aided analysis of prenatal ultrasounds detected heart defects more quickly and accurately than doctors evaluating the tests on their own, according to findings reported Thursday at a meeting of the Society for Maternal-Fetal Medicine in Denver.
“AI-based software significantly improved detection of ultrasounds that were suspicious for congenital heart defects not only among OB-GYNs but also among maternal-fetal medicine subspecialists,” said lead researcher Dr. Jennifer Lam-Rachlin, director of fetal echocardiography at Carnegie Imaging for Women at Mount Sinai West in New York City.
“This has a tremendous impact in terms of neonatal outcomes and has the potential to change clinical practice,” she added in a news release.
About 1 in 4 babies born with a heart defect has one serious enough to require surgery or other medical treatment within the first year of life, researchers said in background notes.
Prenatal ultrasounds can provide an important early warning for such heart defects, but these crucial scans often are analyzed by doctors without extensive training.
“At least half of prenatal ultrasounds in the United States are being looked at by non-specialists, medical professionals — including OB-GYNs — who may not be trained in prenatal ultrasound,” Lam-Rachlin said. “That accounts for why the ability to detect congenital heart defects is still quite low, even in developed countries like the U.S.”
For this study, a group of 14 OB-GYNs and maternal-fetal medicine specialists randomly reviewed 200 prenatal ultrasounds gathered from 11 hospitals in two countries. The doctors ranged in experience from one year on the job to more than three decades.
Sometimes the doctors were assisted by AI in their analysis of the ultrasounds, and sometimes not, researchers said.
Results showed that the AI system significantly improved doctors’ ability to detect cases suspicious for congenital heart defects.
AI boosted the doctors' evaluations regardless of their years of experience or training in the maternal-fetal specialty, researchers said.
Doctors also became more confident in detecting heart defects when aided by AI, and it took them less time to determine whether a case was suspicious or not.
“Most congenital heart defects occur in pregnancies that are considered low risk, which means the pregnant person is most likely being seen by an OB-GYN versus a maternal-fetal medicine subspecialist who has more experience in detecting congenital heart defects,” researcher Christophe Gardella, chief technical officer for BrightHeart, the Paris-based manufacturer of the AI-based software, said in a news release.
BrightHeart received U.S. Food and Drug Administration (FDA) approval for its AI software in November, and is preparing to launch it commercially in the U.S.
“Fetal heart assessments are among the most technically demanding aspects of prenatal ultrasound,” Cécile Dupont, BrightHeart CEO, said in a news release at the time of the FDA approval. “Our AI-powered solution not only assists clinicians in detecting signs of potential abnormalities earlier but also enhances their confidence in confirming normal findings, which is equally critical for the peace of mind of expectant families.”
Findings presented at medical meetings should be considered preliminary until published in a peer-reviewed journal.
