A 55-year-old male was referred to the cardiologist because of the occurrence of two ischaemic strokes within five months’ time in the absence of documented atrial fibrillation. At echocardiography, a membrane was visualised in the left atrium (cor triatriatum) (Fig. 1a). Since no other abnormalities were detected, the cor triatriatum was held responsible for the cardioembolic stroke. Surgical resection of the fenestrated membrane was carried out successfully (Fig. 1b).
