ACC/AHA issue new guideline on managing congenital heart disease in adults

Ensuring ongoing access to care, promoting mental health and physical activity, supporting pregnancy and childbirth, and improving heart failure care identified as key areas of focus for adults who were born with heart defects

2025-12-18

(Press-News.org) WASHINGTON and DALLAS (Dec. 18, 2025) — The American College of Cardiology (ACC) and the American Heart Association, along with several other leading medical associations, have issued a new guideline for managing congenital heart disease in adults. The guideline was jointly published today in JACC, the flagship journal of the American College of Cardiology, and Circulation, the flagship journal of the American Heart Association.

Congenital heart disease—being born with defects in the heart’s structure—is the most common birth defect. According to the Centers for Disease Control and Prevention, it affects nearly 1% of births, or about 40,000 babies per year, in the U.S. Advances in surgical treatments over the last few decades have contributed to over 90% of babies born with heart defects in the United States now surviving well into adulthood. This has led to a rapidly growing population of adults with congenital heart disease (ACHD) who remain at increased risk of cardiac complications as they age, despite early interventions.

The new guideline provides updated recommendations for monitoring, counseling and treating adults with congenital heart disease. It includes evidence from research published between 2017-2024 and replaces the previous guidance issued in 2018.

“We have moved the field forward, in that we have more evidence than we did with the last set of guidelines,” said Michelle Gurvitz, MD, a cardiologist at Boston Children’s Hospital, associate professor of pediatrics at Harvard Medical School and chair of the guideline writing committee. “While we always want more evidence, we are doing better. The growth of the field has been almost exponential in the amount of data being gathered and research being published.”

The new guideline includes additions related to the role of clinicians with specialized expertise in guiding the care of adults with congenital heart disease; updates regarding mental health, physical activity, pregnancy and heart failure; and new recommendations about specific types of heart defects and treatment approaches.

Congenital heart disease encompasses a wide range of conditions, including more than 30 recognized types of heart defects, which can be classified as simple, moderate, or complex. The symptoms or functional differences that result from these defects include abnormal heart rhythms, diminished exercise capacity, low blood oxygen levels, and signs of heart failure, among others. Many people with congenital heart defects are diagnosed early in life and some may undergo surgeries in infancy or early childhood, while a smaller proportion of individuals with milder defects may only learn about their condition during adulthood.

The guideline authors emphasize the importance of access to ongoing specialized care for adults with congenital heart disease. Even when congenital heart defects are diagnosed and treated in childhood, many patients stop seeing congenital heart disease specialists after they become adults. Common barriers include a lack of awareness about the importance of care continuity, availability of specialists where they live, and socioeconomic or insurance-related challenges. The new guideline provides recommendations about when specialized expertise is warranted and how specialists can partner with other clinicians to broaden access to care.

“We know we need to be diligent in our efforts to get pediatric patients into adult congenital heart disease care,” Gurvitz said. “We still have a lot of patients who stop receiving specialized care as they transition and transfer from pediatric to adult care, and a lot of patients who can’t access physicians for other reasons like insurance or geography. ”

Some adults with congenital heart disease experience mental health or neurocognitive conditions—including mood disorders, as well as cognitive and memory problems—that can worsen if they are not diagnosed and treated.

In the new guideline, Gurvitz said, “we renewed our emphasis on mental health and neurocognitive assessment. Our patients have a lot of challenges with anxiety and depression, so it’s important to discuss that with patients or consider sending them for further evaluation.”

The guideline also includes updated recommendations around exercise. Physical activity is an important part of a heart-healthy lifestyle for everyone, including people with congenital heart disease. However, patients with heart defects are often concerned about what level of activity is safe.

“We looked at using exercise testing to guide physical activity recommendations and spelled this out more broadly than in the prior guidelines,” Gurvitz said. “Many of our patients play sports, and we are now saying that adults with CHD are not just ‘allowed’ to play, they are encouraged to participate in physical activity, after being properly evaluated.”

In addition, the guideline includes new and updated recommendations on birth control options, pregnancy and childbirth. Individuals with ACHD interested in pregnancy should receive preconception counseling, in collaboration with an ACHD cardiologist, about genetic testing, how a pregnancy could affect their health, fetal risks associated with pregnancy and safe birthing options. The majority of pregnant patients with ACHD can have a safe delivery, with appropriate individual risk stratification and monitoring.

Updated guidance on surgical practices, heart failure and treatments for specific forms of congenital heart disease is also provided. The writing committee emphasize that patients with more complex heart defects often require close monitoring and may need additional procedures or medical devices during adulthood, such as valve replacements, ablations or pacemakers to correct arrhythmias (irregular heartbeats), or a heart transplant if heart functioning deteriorates severely. Further research is needed to inform the optimal timing for such interventions, as well as to inform geriatric care approaches as more patients reach older adulthood.

“We’ll continue to push the field to answer the questions because the patient population is not going anywhere—it’s only getting larger,” Gurvitz said. “In particular, our most complex patients are our fastest-growing group, and my hope is that some of the identified gaps will push people to try to answer those questions around what is the most efficient and effective way to deliver care to our patients.”

The writing committee included specialists in ACHD cardiology and interventional cardiology, congenital cardiac surgery, heart failure and electrophysiology, in addition to advanced practice nurses and a patient advocate. The guideline was developed in collaboration with and endorsed by the Heart Rhythm Society, the International Society for Adult Congenital Heart Disease and the Society for Cardiovascular Angiography and Interventions.

Cosmic crash caught on camera

2025-12-18

In an unprecedented celestial event, NASA’s Hubble Space Telescope (HST) captured the dramatic aftermath of colliding space rocks within a nearby planetary system. When astronomers initially spotted a bright object in the sky, they assumed it was a dust-covered exoplanet, reflecting starlight. But when the “exoplanet” disappeared and a new bright object appeared, the international team of astrophysicists — including Northwestern University’s Jason Wang — realized these were not planets at all. Instead, they were the illuminated remains of a cosmic fender bender. Two distinct, violent collisions generated two luminous clouds of debris in the ...

Is talented youth nurtured the wrong way? New study shows: top performers develop differently than assumed

2025-12-18

Exceptional performers drive innovation and help solve humanity's most pressing problems. Societies have a vital interest in the development of top performers in various fields. A recent review in the journal Science suggests that gifted education and talent programs have been based on false premises. For the first time, an international, interdisciplinary research team has collated the development of world-class performers in science, classical music, chess, and sports. Traditional research into giftedness and expertise assumes that the key factors to develop outstanding achievements are early performance (e.g., in a school subject, sport, or in concerts) and corresponding abilities ...

Ants: An untapped resource in the development of antibiotics?

2025-12-18

Has a crucial component to the development of human medicine been hiding under our feet? Auburn University Assistant Professor of Entomology Clint Penick and a team of graduate students may have found that ants are far ahead of humans in antibiotic innovation. “In our study, we tested how ants use antibiotic compounds to fight off pathogens and asked why their chemical defenses remain effective over evolutionary time,” Penick said. “Humans have relied on antibiotics for less than a century, yet many pathogens have already evolved resistance, giving rise to ‘superbugs.’’ Ants, by contrast, have been using antibiotics for tens ...

Archaeologists use AI to create prehistoric video game

2025-12-18

Historians and archaeologists are constantly looking for new ways to bring the past to life. And in museums, audiovisual and digital solutions have long been a part of the presentation of cultural heritage. However, until now, developing immersive digital content about the past has been very expensive and has required specialized labour. At the same time, it has been difficult to update the content if needed. For this reason, only large commercial game developers have been successful in making (pre-)history-based video games. Popular examples are Assassin's Creed and Civilisation, which are great, but don't always place ...

Mitochondria migrate toward the cell membrane in response to high glucose levels

2025-12-18

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move remain unclear. Research publishing December 18 in the Cell Press journal Biophysical Journal shows that when beta cells—the pancreatic cells that produce insulin—are exposed to high levels of glucose, their mitochondria move toward the cell’s periphery. This mitochondrial migration could play a role in regulating insulin secretion because beta cells’ mitochondria are responsible for sensing glucose ...

Tiny viral switch offers hope against drug-resistant bacteria

2025-12-18

As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are looking to bacteriophages, viruses that infect bacteria, as an alternative. A new study shows how these phages use a tiny RNA molecule, called PreS, to hijack bacterial cells and boost their own replication. By acting as a hidden genetic “switch” that rewires key bacterial genes, PreS helps the virus copy its DNA more efficiently, offering important insights that could guide the design ...

Most parents aware of early peanut introduction guidelines, but confused about details

2025-12-18

Feeding babies peanut-containing foods as early as possible can help prevent peanut allergy, but a new study published in JAMA Network Open found that parents need more support to get it right. Interviews with parents revealed widespread confusion about the purpose, risks, and timing of early peanut introduction guidelines. “While some parents we talked to understood correctly that starting their baby on peanut foods trains the immune system in order to prevent the development of peanut allergy, other parents mistakenly believed that the purpose is to test if their baby is allergic – a misconception that fueled fears of severe allergic reaction, leading to hesitation and delays ...

HPV vaccine can protect against severe lesions of the vulva and vagina

2025-12-18

Girls who are vaccinated against HPV are not only well protected against cervical cancer; they are also less likely to develop severe precancerous lesions of the vulva and vagina, particularly if they were vaccinated before the age of 17. This is shown in a new study from Karolinska Institutet published in JAMA Oncology. In Sweden, all children in middle school are offered vaccination against human papillomavirus (HPV), which protects against cervical cancer, among other things. HPV can cause high-grade, precancerous lesions and cancer in different parts of the genital area. Researchers at Karolinska Institutet have now shown that ...

Virtual care provision and emergency department use among children and youth

2025-12-18

About The Study: In this population-based cohort study of Ontario children and youth, while emergency department visits following a primary sick visit were infrequent, virtual sick visits to primary care were associated with a small increase in emergency department use in children ages 3 months or older, especially low-acuity emergency department visits. Judicious use of virtual primary care to manage acute illness in children is warranted. Corresponding Author: To contact the corresponding author, Natasha R.
