[Large aneurysm of the left sinus of Valsalva in a 54-year-old man successfully treated with surgery].

Sinus of Valsalva aneurysms are very rare and are often asymptomatic. Clinical manifestations depend on associated complications, most commonly rupture or dissection. We describe the case of a 54-year-old male presenting with exercise-related angina and dyspnea and in whom we found a large unruptured aneurysm of the left sinus of Valsalva. On angiography, he also had a severe stenosis of the left artery descending and the diagonal. He underwent a successful surgical intervention with bypass and closure of the aneurysm.
