Partial Sternectomy to Prevent Rastelli Conduit Compression in Patients With Conotruncal Anomalies.

This report describes 2 cases of redo cardiac surgery in adult patients with conotruncal anomalies (double-outlet right ventricle and transposition of the great arteries) with pulmonary stenosis who underwent the Rastelli procedure in childhood. Although the Rastelli operation is one of the best options for the patients, conduit stenosis has occasionally developed secondary to compression by the anterior chest wall. To prevent compression by the sternum, partial sternectomy with Rastelli conduit change was performed in these 2 patients.
