Left atrial myxomas (LAM), the most common primary tumours of the heart are unusual or rare in the elderly. Moreover, elderly patients often present with non-specific symptoms that are frequently overlooked in the absence of a supporting cardiac history which makes an early diagnosis challenging. Herein, we reported large LAM in 70-year-old Iraqi Kurdish male who was presented with minimal obstructive symptoms and the diagnosis was not suspected clinically but discovered by trans-thoracic echocardiography (TTE) followed by successful surgical excision. Although atrial myxomas are benign, they have potential serious complications which mandate prompt therapy. Due to low morbidity and mortality besides its excellent outcome even in the elderly, surgery is the preferred choice of treatment for LAMs.
