Abstract

Background.

Despite improved surgical results for truncus arteriosus, overall mortality rates, remain higher than those reported for other complex congenital heart diseases, especially with truncal valve regurgitation or an interrupted aortic arch.

Methods.

Seventeen patients had complete repair of the truncus arteriosus at the Cleveland Clinic Foundation between August 1993 and June 1997. The age at operation ranged from 2 days to 4.5 years. Associated abnormalities included interrupted aortic arch in 3 patients and abnormal coronary artery anatomy in 3. Four patients had more than moderate truncal valve insufficiency requiring concomitant truncal valve repair.

Results.

There were no early deaths and only one late death at a mean follow-up of 24 months. The death occurred 3 months postoperatively and resulted from refractory pulmonary vascular obstructive disease in a patient who was referred at 1 year of age. Reoperation was required in 4 patients.

Conclusions.

Even in the presence of associated anomalies complete repair was performed with a low mortality rate. Truncal valve repair can be performed safely in the neonate with good results.
