Abstract:
Pseudoaneurysms arising from the left ventricular outflow tract are rarely reported. We report a 26-year-old man who was admitted with paroxysmal chest pain and dyspnoea on exertion. Computed tomography revealed the presence of a pseudoaneurysm (93 × 77 mm), and the communication was below the aortic annulus. Through median sternotomy, a huge pulsatile pseudoaneurysm was exposed, and an 8-mm-diameter communication of the pseudoaneurysm in the left ventricular outflow tract wall was visualized. The defect was successfully repaired, and the postoperative course was uneventful.
