Logan M. Eberly, M.D., an adult congenital heart disease cardiologist, serves patients across both Norton Heart & Vascular Institute and Norton Children’s Heart Institute, affiliated with the UofL School of Medicine. He brings expertise but also a unique dual perspective to adult congenital heart disease (ACHD) care that is maximizing outcomes.
ACHD represents one of cardiology’s newest and most complex subspecialties that is rapidly evolving.Prior to the development of cardiopulmonary bypass techniques in the 1950s, most children with complex congenital heart disease did not survive into adulthood. Today, approximately 97% of children born with congenital heart disease now survive into adulthood, creating an unprecedented need for specialized adult care.
“The rapid increase in the number of adults living with congenital heart disease has gradually led to the development of ACHD as a formal subspecialty within cardiology,” Dr. Eberly said. “However, the field is quite novel: ACHD only became an [Accreditation Council for Graduate Medical Education] ACGME-accredited fellowship in 2015, with just 24 accredited programs nationwide as of 2021.”Dr. Eberly is excited to bring this type of specialized care to Norton Healthcare and Norton Children’s patients.
Dr. Eberly’s extensive training reflects the demanding requirements for ACHD cardiologists.
After earning his medical degree from the University of Louisville School of Medicine, he completed a combined internal medicine and pediatrics residency at Duke University Medical Center, Durham, North Carolina, followed by fellowships in adult cardiovascular disease at Emory University, Atlanta, Georgia, and adult congenital heart disease at Boston Children’s Hospital, Massachusetts, and Brigham and Women’s Hospital, Boston, Massachusetts.
“Training to be an ACHD cardiologist requires not only understanding complex congenital heart disease, but also being comfortable with managing ‘adult’ medical issues, which include an increasing development of acquired heart disease in the ACHD population as they age,” Dr. Eberly said.
One of Dr. Eberly’s key roles involves managing the transition from pediatric to adult care, which typically occurs in the late teenage years or in a patient’s early 20s and requires careful coordination to ensure continuity of care.
The collaborative nature of ACHD care extends beyond transitions. Collaboration between different providers is common and essential for this patient population, often involving a team of cardiologists, electrophysiologists and other subspecialists.
Dr. Eberly’s practice encompasses several critical areas, including pregnancy care through his work with the Norton Heart & Vascular Institute Women’s Heart Program. Pregnancy is a common reason for referral, and ACHD cardiologists often have more experience and comfort managing both pregnancy and adult cardiovascular disease.
Surprisingly, many ACHD patients still receive their first diagnosis as adults.“It is not uncommon for congenital heart disease to actually be diagnosed for the first time in adulthood, and this population is also a fairly significant portion of our referral base,” Dr. Eberly said.
Central to understanding ACHD is recognizing that childhood surgical interventions represent repairs, not cures.
“The vast majority of patients who have had interventions for their congenital heart disease are not cured. Rather, they are repaired,” Dr. Eberly said. “Most require longitudinal surveillance for potential late complications related to their repair, which highlights the need for lifelong ACHD care.”
These complications emphasize the importance of dedicated ACHD specialists who understand unique surgical repairs and can anticipate potential long-term complications as patients age.
Dr. Eberly’s unique position spanning both Norton Heart & Vascular Institute and Norton Children’s Heart Institute, combined with his expertise in pregnancy and cardiovascular disease, positions him to provide comprehensive care across the full spectrum of ACHD needs.His academic appointment as assistant professor, pediatrics at the UofL School of Medicine further strengthens Norton Healthcare and Norton Children’s ability to serve the region’s growing ACHD population.
For referring physicians, understanding when to involve ACHD specialists is necessary for optimal patient outcomes, whether managing transitions from pediatric to adult care, addressing pregnancy-related concerns or providing ongoing surveillance for patients with potential complications.
Having spent significant time in Louisville during childhood and having completed medical school at the University of Louisville, returning to Louisville was a homecoming for both Dr. Eberly and his wife, a Louisville native.He also was attracted to the professional opportunity to grow and develop the Norton Children’s Heart Institute ACHD program, which includes dedicated ACHD cardiologists, advanced practice providers and social workers. The program is the first in Kentucky accredited as a Comprehensive Care Center, the highest designation, by the Adult Congenital Heart Association. The program, rooted in the expertise of an established pediatric cardiovascular institute bridges the gap for adults who need lifelong care.
“Our ACHD team here is an amazing group of people,” he said.
Outside of medicine, Dr. Eberly stays active through running and cycling (including riding the routes of parts of the Tour de France’s challenging mountain stages) and enjoys spending time with his wife, Ellie, and their two children.
