Left posterolateral thoracotomy: an alternative approach for pulmonary valve replacement.

Pulmonary valve replacement in adults who have a repaired tetralogy of Fallot is realized through a redo median sternotomy. A dilated ascending aorta is often present and adherent to the sternum and can be injured during sternum reentry, with dramatic consequences. We report on an adult patient with a corrected tetralogy of Fallot who underwent pulmonary valve replacement, thick transannular patch excision, and left pulmonary artery enlargement. Surgery was performed through a left posterolateral thoracotomy. This surgical approach was safe and efficient and, compared with the left anterior thoracotomy approach, offered many more possibilities.
