Abstract
Introduction. Cor triatriatum is a rare congenital heart disease found incidentally in children. Although cor triatriatum can be an incidental finding in asymptomatic adults; it is extremely rare to find elderly patients without symptoms and is unique in a long distance runner. Case Presentation. We present the case of an 83-year-old long-distance runner with cor triatriatum sinistrum and atrial fibrillation who continues to be asymptomatic and has continued to run long distances, retaining his excellent functional capacity. Conclusion. Cor triatriatum sinistrum is a rare congenital disease, which is often found incidentally in children. Although it is also seen in adults without symptoms at normal exertion, it is rare to have this condition in long-distance runners especially in elderly people with other structural heart disease, that is, atrial fibrillation and mitral regurgitation.

We report the case of an 83-yearold gentleman who was referred to our clinic after a routine ECG showed atrial fibrillation and subsequent workup with echocardiography revealed cor triatriatum sinistrum and mitral regurgitation
An 83-year-old gentleman was referred to our cardiology clinic, after atrial fibrillation was diagnosed on a routine physical examination by his general practitioner
Summary
Cor triatriatum is a rare congenital heart disease which forms 0.1%–0.4% of congenital heart disease and affects less than 1 in 200000 people (Office of Rare Diseases, National Institutes of Health, USA). We report the case of an 83-yearold gentleman who was referred to our clinic after a routine ECG showed atrial fibrillation and subsequent workup with echocardiography revealed cor triatriatum sinistrum and mitral regurgitation. He had little by way of symptoms and continued long-distance running without any symptoms. To the best of our knowledge, asymptomatic cor triatriatum in an elderly long-distance runner has never been reported
