Arrhythmias are not to blame for all cardiac syncope patients: left atrial myxoma causing syncope in a middle-aged man.

A 47-year-old man presented with a history of syncope that lasted for 3 min and was not accompanied by jerky movement of limbs or incontinence. After regaining consciousness, he felt generalised weakness. There was no history of chest pain or palpitation. ECG showed normal sinus rhythm. All blood investigations were normal. Transthoracic echocardiography showed a large multilobulated echo dense mass in the left atrium. The mass was prolapsing through the mitral valve during diastole. Transoesophageal echocardiography verified these findings and also showed the stalk of the mass attached to the interatrial septum near the fossa ovalis. The mass was highly suggestive of myxoma. The patient underwent surgical resection of the mass and histopathology confirmed the diagnosis of left atrial myxoma.
