What is it about?
This case report describes a 68-year-old man who came to the hospital with chest pain and was found to have a very rare heart condition called anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA). In this condition, one of the main heart arteries connects to the lung artery instead of the aorta. Most people with this condition are diagnosed much earlier in life, so finding it in an older adult is unusual. The diagnosis was confirmed using several imaging tests, including ultrasound of the heart, coronary angiography, CT scan, and cardiac MRI. After reviewing the results, the medical team decided on conservative management rather than surgery, with close monitoring. This case shows that ARCAPA, though rare, can remain unnoticed for decades and may only be discovered later in life when patients present with symptoms.

Why is it important?
t’s important because this case highlights several key points: Rare but real: ARCAPA is extremely uncommon, and most of what doctors know comes from individual case reports. Each new case adds valuable information. Late diagnosis is possible: This patient was 68 years old when the condition was found, showing that some people can live for decades without symptoms. That challenges the assumption that congenital coronary anomalies are always detected earlier in life. Imaging matters: The use of multiple imaging techniques—echo, angiography, CT, and MRI—was crucial for making the correct diagnosis and guiding treatment. Management decisions: Not every patient with ARCAPA requires surgery. Careful assessment and individualized management, as in this case, can be appropriate. Broader lesson: This report reminds clinicians to consider rare congenital anomalies even in older patients with chest pain, and to use a multi-modality approach when evaluating unusual coronary anatomy.
Perspectives
From my perspective, what makes this case remarkable is that such a rare congenital heart condition was only discovered in a man well into his sixties. We often think of anomalies like ARCAPA as something that shows up in childhood or young adulthood, but this reminds us that not all patients follow the usual script. What stood out to me was the role of modern imaging—each test added a new piece to the puzzle, helping us reach a confident diagnosis and plan safe management. It also reinforced that treatment isn’t one-size-fits-all: while surgery is often considered, in this patient a careful, conservative approach with close follow-up was the best option. For me, the case highlights the value of keeping an open mind, using the full range of diagnostic tools, and tailoring care to the individual rather than the textbook.
