The Silent Heart Thief: How a Hidden Defect Surfaced in a 72-Year-Old
"Discover the unexpected link between a congenital heart condition and age-related health issues, revealing the challenges of diagnosis and treatment in elderly patients."
Treating health issues in elderly individuals often presents unique challenges, particularly when congenital heart conditions are diagnosed late in life. Congenital heart defects, present from birth, can sometimes remain undetected until adulthood, leading to complications that require careful and tailored management.
One such condition is Persistent Ductus Arteriosus (PDA), where a blood vessel that should close shortly after birth remains open. This can lead to various heart and lung problems over time. While PDA is relatively common in children, its diagnosis in older adults is rare, making treatment decisions complex.
This article explores the case of a 72-year-old woman with a history of depression, paroxysmal atrial fibrillation, and a previous stroke, who was diagnosed with PDA. Her case highlights the difficulties in managing multiple health issues in elderly patients and the importance of personalized treatment approaches.
Diagnosis and Follow-Up
Persistent ductus arteriosus (PDA) is a congenital cardiovascular malformation connecting the pulmonary trunk or proximal left pulmonary artery with the descending aorta beyond the left subclavian artery. It is usually diagnosed in childhood through echocardiography and cardiac catheterization, although adult cases can remain unidentified. Current follow-up guidance allows patients with trivial, silent, isolated PDA to leave cardiology care, while small PDAs may be reviewed every 2–3 years to monitor for left-heart dilation or consider transcatheter closure. Adult presentation can therefore expose the limitations of childhood-focused detection and surveillance.
A Rare Adult Discovery
Patent ductus arteriosus has an estimated prevalence of approximately 0.05% and is described as the third most common congenital heart disease in adults. Despite that position, PDA is an uncommon clinical finding in adulthood and is usually recognized earlier in life. A reported elderly patient presented with atrial fibrillation, which may result from chronic, progressive left-atrial enlargement. ECG-gated computed tomography angiography helped demonstrate the previously unknown PDA.
Unraveling the Mystery: Diagnosing PDA in Later Life
Persistent Ductus Arteriosus (PDA) is a congenital heart defect that occurs when the ductus arteriosus, a blood vessel connecting the aorta and pulmonary artery, fails to close after birth. While this condition is typically diagnosed and treated in infancy or childhood, it can sometimes go unnoticed until adulthood.
- Shortness of breath
- Fatigue
- Heart murmur
- Pulmonary hypertension
Late-Life Case Reports
Recent literature continues to document PDA in older adults through individual case reports. One report described a 73-year-old man whose symptoms included dyspnea, cold sweating, and burning chest pain lasting 30 minutes, with the defect diagnosed during coronary artery bypass grafting. Another publication identified a septuagenarian with two congenital left-to-right shunt anomalies. A 2026 review defines PDA as a persistent communication between the pulmonary artery and aorta that normally closes before birth.
The Cost of Late Recognition
A case report described a 72-year-old woman with persistent ductus arteriosus Botalli, depression syndrome, paroxysmal atrial fibrillation, and a history of cerebral stroke. The report identifies PDA in patients older than 65 as a rare finding. At follow-up, the patient remained under outpatient treatment, and no cerebrovascular episodes had been recorded so far. This single case illustrates that late recognition may coexist with substantial neurologic and rhythm-related clinical history, while not establishing outcomes for older patients generally.
Treatment Choices and Bleeding Risk
A case report on an 87-year-old woman examined the safety and timing of resuming dabigatran after massive rectal bleeding in the setting of atrial fibrillation. Separately, a surgical series involving 1,013 patients noted that different management strategies may be used when PDA occurs alongside other congenital heart diseases. These reports address different clinical decisions: anticoagulation after major bleeding and selection of PDA management in patients with associated defects. Neither source directly establishes that one approach is superior across all older adults.
Navigating Treatment Challenges and Personalized Care
Treating elderly patients with PDA requires a careful and individualized approach. The presence of other health conditions, such as depression and atrial fibrillation, can complicate treatment decisions. Balancing the benefits and risks of interventions, such as surgery or medication, is crucial to ensure the best possible outcome for the patient. Close monitoring and collaboration among healthcare providers are essential to manage these complex cases effectively. In the case of the 72-year-old woman, her successful management highlights the importance of personalized care and attention to both physical and mental well-being.
AI and Percutaneous Care
Artificial-intelligence research describes PDA as a complex and heterogeneous condition with dynamic physiology, changing disease severity, and frequent comorbidities in a vulnerable population. The European Society of Cardiology reports that percutaneous congenital-heart interventions began with PDA as the first treatment target. The same review notes that congenital heart disease also advanced transcatheter valve technology, including Philipp Bonhoeffer’s first transcutaneous, transcatheter valve implantation in June 2000. Together, these developments point toward more individualized assessment and minimally invasive intervention.
The Adult Diagnostic Gap
Persistent ductus arteriosus is usually diagnosed in early childhood using echocardiography and cardiac catheterization. In older patients, computed tomography and cardiac magnetic resonance are described as excellent noninvasive methods when additional quantification of right- or left-ventricular size, shunt volume, or pulmonary arterial hypertension is needed. A reported case involved an 86-year-old woman with symptoms attributed to an undiagnosed PDA. The need for advanced imaging in such presentations underscores the challenge of detecting congenital defects that remain hidden into late adulthood.
