A 3-year-old girl with Fallot's tetralogy underwent balloon pulmonary valvoplasty without any obvious complications. Elective total correction was performed 15 months later. At operation, a well-healed longitudinal tear measuring 2 cm was noted in the posterior wall of the main pulmonary artery 1 cm from the pulmonary valve extending into the right pulmonary artery.
