An unusual cause of pulmonary edema: acute rupture of noncoronary sinus of Valsalva aneurysm into the left atrium

We present the case of a patient admitted to hospital with pulmonary edema and atrial fibrillation. The transthoracic echocardiogram showed noncoronary sinus of Valsalva aneurysm ruptured into the left atrium, with a turbulent flow directed toward the left atrium floor and the pulmonary vein, which explained the clinical presentation. Echocardiography played a crucial role in identification of the cause and correct therapeutic approach.
