(Press-News.org) DURHAM, N.C. – Children born with single‑ventricle heart disease, a rare and serious heart defect, often undergo multiple surgeries in their first years of life. A new study shows the challenges for these children can last well into adolescence and sometimes throughout their lives.
Researchers from Duke Health and the Pediatric Heart Network followed 549 children with single ventricle heart disease for 16 years and found that 87% either died or developed a major health problem over time. Only 12% reached adolescence without a significant complication.
These findings, published in the Journal of the American College of Cardiology March 11, give families a clearer picture of what to expect and offer the medical community new direction for improving care.
“Now that we understand these trajectories and the risk factors for suboptimal outcomes, we can counsel families more clearly and tailor therapies to each child,” said Kevin D. Hill, M.D., corresponding author, chief of division of pediatric cardiology and professor in the Department of Pediatrics at Duke University School of Medicine.
The study introduces a new way of evaluating long term health called a global rank score. It’s a measure developed with input from families that captures what matters most to them, including daily functioning, quality of life, and heart performance.
One of the most important findings for families is that most children will continue to need specialized care long after surgery. The study found high rates of adaptive behavior delays, quality of life challenges, and reduced heart function in many patients, often emerging gradually as they grow.
Researchers also found that premature babies faced the steepest uphill climb. More than 60% of premature infants in the study died, and only 3% reached adolescence without major problems. The data suggests that supporting healthy pregnancies and preventing preterm birth could make a meaningful difference.
For clinicians, the study provides new clues that may help tailor early surgical decisions. Although the two main shunt types used in infancy showed similar long-term outcomes overall, babies who had moderate or severe tricuspid valve leakage before surgery did worse with the right ventricle shunt, a finding that could guide future decision making.
Just as importantly, the study revealed substantial differences among hospitals. Some centers had lower early mortality, while others excelled in long term follow up and rehabilitation. This variation highlights opportunities to share best practices and improve care no matter where a child is treated.
“These children need lifelong comprehensive care, including medical, developmental, and school support,” Hill said. “It’s not like they get surgery and are ‘fixed.’ Ongoing, coordinated services are essential to help them thrive.”
The study emphasizes that children with single ventricle heart disease often face challenges in multiple areas of life. The research team hopes these findings will help families feel better prepared, while giving healthcare teams a roadmap for improving outcomes through physical therapy, mental health support, school accommodations, exercise programs, and strong long-term monitoring.
In addition to Hill, study authors include, Lillian Kang, Qiao Wang, Jane W Newburger, J. William Gaynor, Kristin M. Burns, Richard Williams, Felicia Trachtenberg, Brian W. McCrindle, Eric M. Graham, Christian Pizarro, Awais Ashfaq, Andrew Souza, James A. Kuo, Dawn Ilardi, Kurt R. Schumacher, Hwanhee Hong, and Caren S. Goldberg.

The disposable vapes ban in the UK could lead to young adults switching to alternative products, including cigarettes, new research led by the University of Bristol has found.
In response to rising concerns about youth vaping, the UK Government introduced a ban on disposable vapes last year (from 1 June 2025). While the ban was intended to curb underage use, its possible impact on around the 2.5 million adults in the UK who rely on disposable vapes is unclear.

According to a recent multi-institute PLOS One study led by the Multisensory Research Lab at the Wilmer Eye Institute, Johns Hopkins Medicine, time of hearing loss onset is a key determinant of patient confidence and self-reported sound localization abilities — the ability to perceive and locate objects in an environment — even in individuals who use hearing aids or who have received vision rehabilitation training.
The National Institutes of Health-supported study highlights factors that shape how people with dual sensory ...

While women living in rural regions are known to face a higher risk of advanced breast cancer, a new analysis found that even within rural America, outcomes differ sharply based on region and other factors.
Women living in the South, Black and Hispanic women, and women without insurance are significantly more likely to be diagnosed with Stage 3 or 4 breast cancer.
Region-specific solutions, including rural surgeon training and targeted health policies, may help reduce disparities.

WEST LAFAYETTE, Ind. — Wavelogix, a manufacturer of novel, patented concrete strength sensors invented at Purdue University’s College of Engineering, has received a $500,000 Small Business Innovation Research (SBIR) Phase IIB grant from the National Science Foundation’s (NSF) Directorate for Technology, Innovation and Partnerships.
The grant builds upon an SBIR Phase II grant awarded in 2024. The Phase IIB project is scheduled to end in December 2026.

Californians have long dealt with wildfire smoke as a seasonal fact of life, but those fires have become more intense and frequent, raising the profile of wildfire smoke as a public health issue. Now, a study led by researchers at UC San Diego’s Scripps Institution of Oceanography finds that the time between multi-day smoke events is shrinking — leaving communities with less time to recover before smoke returns.
The new study, published March 11 in the journal GeoHealth, found that in California the window of cleaner air between smoke waves shrank by more than 60% from 2006 to 2020. The study also finds that ...
Employment can be a powerful gateway to independence, dignity and belonging. Yet for individuals with intellectual and developmental disabilities (IDD), that gateway remains limited. Although work supports better health, social connection and a sense of purpose, only about 15% of individuals with IDD are employed in competitive, integrated work settings.
This disparity persists despite federal programs like supported employment, which offers ongoing job coaching to help people with significant disabilities find and keep competitive jobs, and customized employment, which adapts job roles to match the strengths and needs of both employees and employers. This highlights a critical gap ...
Medical debt is associated with deferred dental care, medical care, and mental health care, even among people with health insurance, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health.
The study found that 42.3% of people with medical debt delayed dental care compared with 17.7% of those without—almost 2.4 times as many; 23.0% of people with medical debt delayed medical care compared with just 5.3% of those without—about 4.3 times as many; and 14% of people with medical ...

Prior authorization, a process that requires physicians to obtain approval from health care insurers before certain treatments are covered, may keep patients from filling prescriptions for two critical heart failure drugs, a new study shows.
Led by NYU Langone Health researchers, the analysis focused on angiotensin receptor-neprilysin inhibitors (ARNIs) and sodium-glucose cotransporter-2 (SGLT2) inhibitors, which are pillars of modern heart failure treatment. The drugs have no generic alternatives and can cost hundreds of dollars out of pocket. While they have been shown to substantially reduce the risk of death when added to standard therapy, ...
Three principles - transparency, credit, and accountability – should form the foundation for “responsible authorship”, argues a working group comprising scholars, scientists and journal editors. In an article published March 10 in the Proceedings of the National Academy of Sciences (PNAS), the group, led by PLOS’ Chief Scientific Officer Veronique Kiermer, states that contributions worthy of authorship should be determined by who has accountability for the research, and that all who claim the credit implied by authorship must assume that accountability.
Who ...
