title: [Rupture of the left sinus of Valsalva forming a subepicardial pseudoaneurysm].
abstract: A healthy 44 year-old male patient presented a calcified mass in the middle mediastinum on a chest film. During diagnostic investigation cineangiograms showed a rupture of the left sinus of Valsalva forming a large pseudoaneurysm that produced important distortion of the left coronary artery and it's main branches. The patient was submitted to surgical repair through the closure of the orifice of the ruptured left sinus of Valsalva with a bovine pericardium patch. The subepicardium was filled with organized thrombi which were removed. He was discharged from the hospital after uncomplicated postoperative course. Pathological examination of the aortic fragment did not yield the etiology of the rupture.
