Surgical treatment of a pulmonary artery aneurysm due to a regurgitant quadricuspid pulmonary valve.

We report the case of a patient with a pulmonary artery (PA) aneurysm secondary to a regurgitant quadricuspid pulmonary valve, in which both lesions were successfully repaired. The patient, a 16-year old boy, was known to have had pulmonary regurgitation and progressive dilation of the PA for years. He was operated on when he developed symptoms of effort, a dilated right ventricle and a PA of 55 mm.
